132 Tips to Most Efficient Natural Gas Water Heater | Rheem Water Heater

  • In the battle of storage tank water heaters versus tankless water heaters, tankless wins in almost every category. However, you’ll pay more to purchase and install the tankless water heater. Ultimately, if price is a concern, it’s a good idea to use calculators to determine capacity needs and energy usage to find the break-even point for the higher initial cost of the tankless water heater compared to energy efficiency savings. - Source: Internet
  • Do not confuse a tankless coil with a tankless water heater or an indirect water heater. Tankless coils use the home’s existing boiler — they are most common with older boilers — as the heat source for water heating with no storage tank. When hot water is drawn from the tap, the water circulates through a heat exchanger in the boiler. Tankless coils work great as long as the boiler is running regularly (during the winter months), but during summer, spring, and fall, the boiler has to cycle on and off frequently, wasting a lot of energy. Instead, ACEEE recommends an “indirect” tank-type storage water heater, or a free-standing storage water heater. - Source: Internet
  • If you plan to use a tankless water heater for your whole home, then consider a heat pump water heater. They are the most energy efficient type of water heater and will save you thousands over their lifespan. If that’s of interest check out this article: Heat pump water heater reviews. - Source: Internet
  • If you have a typical home water heater, you might want to get a larger one if you often have multiple showers taken. While this option may relieve the hot water shortage, but your energy bills will increase along with your hot water availability. Average storage tank water heaters can only support three showers in a row. You won’t like being the fourth shower-taker unless you prefer chilly, not hot, showers - Source: Internet
  • Households using electric water heating and a heat pump for space conditioning can reduce water heating costs by installing a “hybrid” heat pump system. Fully integrated single-unit systems are one option, or an existing heat pump and storage water heater can be retrofit with a specially designed add-on heat pump water heater module. Hybrid air- and ground-source heat pump systems are available. - Source: Internet
  • Also known as demand-type or instantaneous water heaters, tankless water heaters are an option to avoid unnecessary heating costs related to standby heat loss. That’s because instead of holding a tank of water that continually heats throughout the day, tankless water heaters provide hot water only as needed. Just turn on a faucet and you get hot water instantly. - Source: Internet
  • Add Up Your Savings Find out how much you can save on energy costs when you purchase your Rheem Hybrid Electric Water Heater. Added smart features like exclusive Water Leak Detection Alerts and vacation setting, plus energy cost savings and our 10-year warranty all add up for a quick payback in two years or less11 and big savings over the life of the water heater.

  • — Compared to a conventional tank, tankless models won’t leak a lot of water, build up Legionella bacteria, or tip over in an Earthquake. The air supply and exhaust vents are also sealed which means you don’t have to worry about gas leaks or carbon monoxide poisoning. Easier to winterize — Getting your tankless hot water heater ready for winter takes seconds compared to conventional tanks that take a long time to drain. - Source: Internet
  • For this reason, many water heaters are placed in the garage or basement where any added heat won’t affect the living areas of your home. However, because they’re inexpensive, gas powered storage water heaters are the most common form of water heater, according to Smarter House. Additionally, gas water heaters typically last between 10-15 years depending on how well they are maintained, making it easy to replace and forget. - Source: Internet
  • If you’re like most people, you’re unlikely to go out looking for a water heater until your existing one fails. That will happen at the worst possible time — like just after guests arrive for a week-long visit. You’ll have to rush out and put in whatever is available, without taking the time to look for a water heater that best fits your needs and offers real energy efficiency. A much better approach is to do some research now. - Source: Internet
  • This appears small but as noted earlier, methane is 86 times more powerful than CO 2 from a heat-trapping perspective over a 20-year horizon. A small amount of leakage adds up to a large impact. In fact, while tankless water heaters are theoretically 22 percent more energy efficient than tank heaters, this advantage is in part offset by the higher methane emissions. NRDC estimates that when factoring in methane emissions rates per the study’s findings, tankless water heaters only reduce emissions by 14 percent vs. gas tank heaters, instead of the 22 percent conventional estimate. - Source: Internet
  • A push-button ignition makes starting up the heater easy, with an LED status indicator to help you keep track of things in case something goes wrong. A renowned and trusted brand, A.O Smith offers a good, reliable water heater for an affordable price. - Source: Internet
  • Its tank is glass-lined, which makes it great for insulation and has a 98% thermal efficiency. For a water heater that can be used with one point-of-use, the Bosch model is a great choice. It’s fine to use when one person has a shower for around 10 minutes, or it can be used with a small washing machine. - Source: Internet
  • Tankless water heaters, also known as on-demand water heaters, use high-powered burners to rapidly heat water as it runs through a heat exchanger and deliver it directly to your faucets or shower without storing it in a tank. Tankless water heaters are usually powered with electricity or gas. These types of water heaters were found to be 22 percent more energy efficient on average than the gas-fired storage-tank models in tests conducted by Consumer Reports. - Source: Internet
  • Buying too large a storage water heater will reduce energy performance by increasing the standby losses. If gas- or oil-fired, larger systems will also lose more heat up the flue. Demand water heaters should be sized according to the required gpm flow rate and temperature rise during the winter required for your largest expected hot water fixture (usually a shower). (See “Demand Water Heaters.”) - Source: Internet
  • A gas tankless water heater is entirely different than an electric tankless water heater. In fact, about the only common thing they share is that, in the end, they both heat water! There are a lot of things to consider when choosing a tankless water heater, and your ultimate goal is to purchase the best type to meet your household requirements. This article will compare both gas fueled and electric fueled tankless water heaters so that you can take a close look at how they match up to each other in each category. Let’s get started! - Source: Internet
  • If your bank account can manage the higher initial cost of a tankless water heater, you’ll save more money over time by choosing tankless. But, if you are on a fixed modest income, a storage tank water heater might make more sense for you. Discuss the two types of water heaters with your plumber to weigh your options. - Source: Internet
  • The cost of a tankless water heater is usually between $1,000-$4,500. You will probably hear people talk about the total installed cost. That’s another way of saying the cost of the unit, labor and parts. This is a better way to look at it than simply looking at the tankless water heater price. Below we’ll break down those costs in more detail and help you understand a tankless water heater average cost. - Source: Internet
  • Every hot water system is different, with some more efficient than others. As water heating generally comprises a quarter of the typical household energy bill, it makes sense to get a system that works best for you. So which option offers the greatest efficiency for your home? - Source: Internet
  • A heat-pump water heater uses heat from the surrounding air to heat water in a storage tank. An electric heat-pump hot water heater uses much less electricity than an electric storage water heater, and are the most efficient hot water systems on the market. These systems can provide additional economic and environmental benefits if your home has a Solar PV system that is generating more electricity than your household’s daytime demand, as a heat-pump hot water heater can increase self-consumption of onsite solar generation. - Source: Internet
  • The easiest way to identify an efficient water heater is to look for the ENERGY STAR symbol. All ENERGY STAR certified products are tested to strict efficiency standards and are certified by an independent third party. They perform the same as or better than standard products without compromising performance in any way. - Source: Internet
  • Solar-powered circulators are available for solar water heaters — once you’re using solar power for water heating, why not also supplement the electricity needed to run the system? These are available from several manufacturers. If you are considering a solar water heater, ask your installer about this option. Drainwater recovery devices can be installed in the drainage lines beneath showers and other hot water uses to recapture some of the heat returning to the pipe and transfer it back to the water heater. The most common example of this type of product is the GFX (gravity film exchange) by Doucette Industries. - Source: Internet
  • A relatively new option in electric heating is the heat pump device. These units extract heat from the surrounding air to heat water. Electric resistance elements are still present to provide backup heating. Heat pump units are by far the most efficient domestic water heaters, but they are much more expensive than other options. - Source: Internet
  • If your house doesn’t have the necessary electrical power to operate an electric tankless system, you can hire an electrician to do a power upgrade. Keep in mind that this will significantly increase your installation costs. Environmental Impact Whether you worry about greenhouse gases or your carbon foot print, it’s always a nice feeling to know that energy efficiency will not only help your pocket book, but it’ll also help our planet. Gas Tankless Water Heater Gas fueled tankless water heaters are more energy efficient than traditional tank-style water heaters. - Source: Internet
  • — Using a tankless hot water heater can save you hundreds of dollars per year. A typical 40 gallon electric water heater will cost anywhere from $200 per year for the most efficient models to $800 for the least efficient models, tankless models often cost less than $100 per year to operate. More environmentally friendly — Because tankless hot water heaters use less energy, they also generate less emissions. That means a lower carbon footprint. Though it’s worth pointing out that they aren’t as environmentally-friendly as heat pump water heaters (also called hybrid water heaters). - Source: Internet
  • You might be tempted when shopping around for your water heater to make a decision based on features and price alone. But the importance of a good warranty shouldn’t be overlooked, as in a crisis, you’ll want to feel reassured you can get your home back up and running again. So, if you don’t want to be left without hot water for a long stretch of time, then pay close attention to a model with a strong guarantee. - Source: Internet
  • A solar water heater consists of a solar thermal collector attached to a south-facing sloped roof or wall, a well-insulated storage tank, and a fluid system that connects the two. It is usually preferable to use a two-tank system in which the solar water heater circulates water through the collectors and back into a separate tank that then “preheats” the conventional water heater. The distance between the collector and the tank, or the amount of finished space the loop must traverse in a retrofit installation, impacts the method and cost of installation. - Source: Internet
  • There should be instructions within the manual you received from the manufacturer on the purchase of your heater. If you’re in doubt at all, then this manual should help you know exactly how to do a checkup on your appliance. If you can’t get the help you need from the manual and need to check the condition of your heater, then you can always call a local plumber to get professional advice. - Source: Internet
  • Water heaters last for 10 to 15 years and can be expensive to replace. When your water heater gets close to its end-of-life, consider upgrading to an electric heat pump water heater. Even if you currently use gas for water heating, an electric heat pump water heater is so much more efficient than even the best gas models, it will save energy and money over its life. Make sure to research available options and when possible, go ahead with the replacement before your water heater fails, as it is easier to upgrade when you can plan for it than in an emergency situation. - Source: Internet
  • Indirect water heaters. Indirect water heaters generally use the home’s boiler as the heat source, circulating water from the boiler through a heat exchanger in a separate insulated tank. Since hot water is stored in an insulated storage tank, the boiler does not have to turn on and off as frequently, improving its fuel economy. Electronic controls determine when water in the tank falls below a preset temperature and trigger the boiler to heat the water as long as needed. The more sophisticated of these systems rely on a heat purge cycle to circulate leftover heat remaining in the heat exchanger into the water storage tank after the boiler shuts down, thereby further improving overall system efficiency. - Source: Internet
  • Electric storage hot water systems – the most common type in Victoria – heat water with an element in the bottom of the unit and store it in an insulated tank, ready for use throughout the day. Electric hot water systems are the cheapest to buy but the most expensive to run. If you have an existing electric hot water system, you should consider taking advantage of the government incentives available to upgrade to efficient heat-pump options. - Source: Internet
  • Canadians use an average of 75 litres of hot water each at home every day—for washing dishes and clothing, cleaning and showering or bathing. Water heaters account for 17.2% of the energy used in the average Canadian home, and 5.7% of the energy used in the average commercial or institutional setting. - Source: Internet
  • Solar water heaters. As the name implies, these use energy from the sun to heat water, or help heat water. Solar water heaters can be a great investment because they offer a virtually cost-free and renewable energy source for one of your home’s top energy users. But because the feasibility and benefits of a solar water heater will vary based on variables such as where you live, which way your roof is facing, and how many people live in your house, it takes some extra savvy to know what your costs and savings will be. - Source: Internet
  • Demand or instantaneous water heaters do not have a storage tank. A gas burner or electric element heats water only when there is a demand. Hot water never runs out, but the flow rate (gallons of hot water per minute [gpm]) may be limited. By minimizing standby losses from the tank, energy consumption can be reduced by 10–15%. Before buying a demand water heater, though, be aware that they aren’t appropriate for every situation. - Source: Internet
  • On-demand recirculation systems eliminate the energy, time, and water wasted when waiting for hot water to reach the faucet. The best systems add a connecting loop, a pump, and a controller between the hot and cold water lines at the furthest fixture from the water heater. When activated by the push of a button, a pump rapidly circulates hot water to the fixture, and the roomtemperature water in the pipes is returned to the water heater. These systems are relatively easy do-it-yourself installations. Available products include the ACT Metlund® D’Mand® and Taco D’Mand® Systems. - Source: Internet
  • For consumers, gas is almost always a cheaper option than electricity, and this simple fact has been enough for many homeowners to choose gas water heaters. If a gas line is already available in a house, it is a much cheaper option. Switching over from electric to gas can be expensive, because it may require installation of a gas line and venting for exhaust heat. Gas heaters can have a slightly shorter lifespan, but the difference is not significant (12 instead of 13 years, for example). - Source: Internet
  • Although it’s tempting to open the installation manual and install your new water heater on your own, most homeowners don’t have the necessary skills and experience. By choosing a professional installer, you get someone who knows exactly what to do and how to do it correctly and safely. Furthermore, some brands only sell their water heaters through installers. Installers also often have water heater suggestions for your home. - Source: Internet

  • Tankless water heater price — The price of the unit itself will of course have the biggest impact on the total tankless water heater cost. The cheapest electric tankless water heater costs about $360. The most expensive models cost as much as $2,500. The factor that will influence the tankless water heater price the most is the GPM capacity. The higher the capacity, the higher the price of an on-demand water heater. - Source: Internet
  • Once promoted as a more energy efficient option for providing hot water in homes and businesses than conventional tank-type water heaters, gas tankless water heaters may not be that much better for the climate when accounting for methane emissions—the primary component of gas and a climate-warming super pollutant—finds a study by Stanford researchers. These tankless water heaters emit twice as much unburnt methane because they fire up their gas burners, and release a puff of methane, every time hot water is used. This is true even when only a small amount of water is used, like for hand washing or rinsing a cup. - Source: Internet
  • — Because tankless hot water heaters use less energy, they also generate less emissions. That means a lower carbon footprint. Though it’s worth pointing out that they aren’t as environmentally-friendly as heat pump water heaters (also called hybrid water heaters). Less space — Tankless water heaters are smaller and can be mounted on the wall, which means they can easily be stored in small laundry rooms and closets. - Source: Internet
  • The largest readily available gas-fired demand water heaters can supply about 5 gallons of hot water per minute with a temperature rise of 77°F (58° to 135°F, for example). 77°F is the basis for industry calculations. This would support two simultaneous showers, or a bit more if the hot water is “mixed down” with a lot of cold water. If you’ve installed a low-flow showerhead (see “Conserve Water” below) and won’t need to do a load of laundry or dishes while someone is taking a shower, then 4–5 gpm might be fine. But if you have a couple of teenagers in the house, or if you need hot water for several tasks, a demand water heater might require staging some uses. - Source: Internet
  • From the table, we see that when both purchase and operating costs are taken into account, one of the least expensive systems to buy (conventional electric storage) is one of the most costly to operate over its expected 13-year life. An electric heat pump water heater, though expensive to purchase, has a much lower cost over the long term. A solar water heating system, which costs the most to buy, has the lowest yearly operating cost among electric systems. - Source: Internet
  • Integrated “combi” water heaters. If you’re building a new home or upgrading your heating system at the same time you’re choosing a new water heater, you might consider a combination water heater and space heating system. These systems, also called dual integrated appliances, put water heating and space heating functions in one package. Space heating is provided via warm-air distribution. - Source: Internet
  • If you have extra money to invest now and want to do more for the environment, a solar water heater can be a good choice in most areas today. But make sure you find a qualified installer who can properly design and size the back-up water heating system. Solar water heaters can be particularly effective if they are designed for three-season use, with your heating system providing hot water during the winter months. - Source: Internet
  • Electric tankless water heaters require very little maintenance. In fact, other than cleaning the inlet screen filter occasionally, electric tankless water heaters generally do not require any maintenance. On the other hand, gas tankless heaters should be inspected annually by a trained technician to ensure safe fuel combustion and performance. In the event of a problem, electric units are inherently simpler to troubleshoot, diagnose, and repair, and the simplicity of their design means that they tend to last a lot longer. Gas tankless water heaters have very complex heat exchangers and fuel controls that are much more difficult to service in the field. - Source: Internet

  • There is a tradeoff when choosing to go with a tankless water heater. To start, you’ll only get hot water if you’re drawing less than a few litres a minute. That’s enough for a shower or a bath. Multiple showers or a shower plus your washing machine or dishwasher running may be too much for just one tankless water heater. - Source: Internet
  • Today’s natural gas water heaters are the most efficient models on the market. Compared to electric water heaters, they’re less expensive to operate, they heat water faster, and they provide hot water even when the electricity goes out. They’re more durable, since the flame does all the work and there are fewer parts to fail or wear out. And, they come in a variety of sizes so you can select one to best meet your needs. - Source: Internet
  • While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency usually peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. Even though natural gas is generally a cheaper input fuel than electricity per BTU of output power, this benefit is generally outweighed by the higher efficiency of the electric unit, longer service life, and cheaper installation. On top of that, electric tankless water heaters cost much less than most tankless gas models. Moreover, gas prices tend to fluctuate more dramatically then electricity prices and most economists agree that gas prices are expected to rise significantly in coming years, whereas in most areas, electricity prices should be relatively stable or at least rise at a much slower pace. - Source: Internet

Whether it’s the best electric water heater or gas water heater, you’ll want it to be as energy-efficient as possible too. - Source: Internet
  • All other things being equal, the smaller the water heater tank, the higher the efficiency rating. Compared to small tanks, large tanks have a greater surface area, which increases heat loss from the tank and decreases the energy efficiency somewhat, as mentioned above. If your utility company offers off-peak electric rates and you’d like to use them, you may need to buy a larger water heater to provide carry-over hot water for periods when electricity is not available under this “tariff.” - Source: Internet
  • The high-efficiency option for gas heaters is condensing boilers. These units use heat from the exhaust gases to preheat cold water coming into the tank. This can achieve a 20% increase in efficiency over traditional gas storage units. However, the initial cost of condensing boilers is about twice that of a traditional unit. - Source: Internet
  • Water heaters can be powered by natural gas, propane, fuel oil, or electricity. It can be expensive to cycle water throughout the day when people in your household take a shower or run the water. Expenses can also increase due to standby heat loss, which is caused when the hot water in the tank drops below a certain temperature. Choosing the right energy plan, can help you manage these energy costs. - Source: Internet
  • In recent years tankless hot water heaters (again, some people call these on-demand hot water heaters) have become increasingly popular in America. Compared to conventional an electric water heater, they are much cheaper to operate since they only heat water when you need it. They also take up much less space in your home than the more energy efficient hybrid water heater. However, if you are switching from a conventional tank, the installation cost will be higher. - Source: Internet

  • Efficiency and tank size. The energy efficiency of a storage water heater is indicated by its energy factor (EF), an overall measure of efficiency based on the assumed use of 64 gallons of hot water per day, regardless of tank size. The first national appliance efficiency standards for water heaters took effect in 1990. Updated standards, effective in 2015, are summarized in Table 6.1. - Source: Internet
  • Installation cost in your area may vary. Areas that receive sun consistently for 3 or more seasons will not only save more energy, but consumers are likely to have more products to choose from at lower costs. Plus, new federal tax credits (set to run through 2016) coupled with state-level incentives available in a number of jurisdictions present additional incentives for purchasing solar water heaters. - Source: Internet
  • Hybrid gas water heaters. Broadly speaking, the term refers to water heaters with more than two gallons storage, but less storage than expected from output capacity. They feature a condensing burner smaller than used on whole-house tankless units and enough storage to have high first hour ratings. The smaller burner means they generally will not require new gas lines for retrofit installations. Because the burner is > 75,000 Btuh, they will be classed and rated as commercial products, although marketed for residential use. - Source: Internet

  • — Your plumber may need to use connectors, fittings, mounting hardware, and other parts during the install. According to Homewyse, this should cost about $50. Disposal — A plumber may charge beween $25 to $500 to remove your old hot water heater and dispose of it properly. (This large range is why we recommend getting multiple quotes so that you can compare each plumber and get the best deal). - Source: Internet
  • Electric vs. gas? Water heaters that have tanks or tankless designs? What’s right for you and your home? Whatever you decide, new energy-efficient water heaters use less energy and are offered in a variety of options, while also heating water faster than older models. Some even heat water instantaneously and don’t have a tank at all. - Source: Internet
  • There are two basic types of tankless water heaters: gas (including both natural gas and propane (LP)) and electric (which comes in both whole-home and point-of-use configurations). Gas tankless water heaters are less expensive to operate, but they typically require venting—outdoor models are the notable exception. Electric tankless water heaters don’t require venting, and because they usually only require a dedicated electrical circuit, they’re easier to install. What may ultimately help make the decision is where you need the hot water: - Source: Internet
  • A gas water heater uses the heat from burning a fuel (usually natural gas) to heat water, while an electric water heater uses electric resistance coils. Gas water heaters are less energy efficient than electric heaters, but the cost of electricity itself makes the running costs of an electric heater higher. Gas water heaters also have a much faster recovery rate, which makes them a convenient option for larger families. - Source: Internet
  • Because average water supply inlet temperature varies by location, the ideal tankless water heater in the south might not work at all in the north. And a tankless gas water heater might work great at 8,000 ft. altitude, but not work at all at 12,000 ft. - Source: Internet
  • Water-heating is the largest use of gas in California homes, and second-largest in homes nationally after space heating. And the vast majority of new water heaters sold in the state today use gas. The tankless heaters save energy because they use electronic ignition instead of pilot lights, and they also don’t need to store water in a tank, where it gradually loses heat until it gets reheated. However, this conventional math only accounts for energy use, and carbon dioxide (CO 2 ) emissions, the primary by-product of gas combustion. The Stanford study finds that gas tankless water heaters leak more than twice the amount of methane (CH 4 ) than gas tank types do. - Source: Internet
  • While traditional gas and electric storage units are similar in initial purchase price, electricity costs more to use than gas, that means over time, electric units are more expensive to operate. Installation of an electric water heater can be made more expensive by the requirement for a 220 volt outlet, and the wiring for this in an electrical panel. Electric water heaters may have a slightly longer lifespan than gas units, but this largely depends on local water quality and owner maintenance. - Source: Internet
  • With solar water heaters, you should discuss your requirements carefully with the solar water heating salesperson. You will need to size both the solar hot water system itself and the back-up electric or gas water heater. It generally makes the most sense to size a solar water heater to provide almost all of the hot water needed during a peak summer day. This is economically sound, but will require supplemental water heating in other seasons and on cloudy days. - Source: Internet
  • Whether you’re replacing a worn-out existing water heater or looking for the best model for a new house you’re building, choose carefully. Look for a water heater that satisfies your hot water needs and uses as little energy as possible. Often you can substantially reduce your hot water needs through water conservation efforts (see “Conserve Water”). - Source: Internet
  • Tank Water Heaters: Traditional storage tank water heaters are still the most common type. These units store hot water in an insulated tank. The upfront investment in a storage tank water heater is generally less than for a tankless unit, but efficiency can vary depending on the unit and fuel source.

  • Most cities and counties require you apply for a permit before you install a water heater in your home. Depending on where you live, the licensed plumber you hire can obtain the necessary permits as part of the installation. However, it’s a good idea to double-check with them or your local building department to learn exact permit requirements for your location. This will also help you find out if you need to get the permit yourself or if the contractor does it. When the installation is complete, someone from the organization that issued the permit will inspect the water heater to verify it complies with the building code. - Source: Internet
  • Conventional gas storage units are relatively inefficient because of the heat loss from exhaust gases and walls of the storage tank. Water is kept hot at all times, and while this is a good convenience, it means energy is constantly used/lost. However, modern units are increasingly efficient, and top-of-the-line condensing units are very energy efficient. Two inches of foam insulating around the storage tank can significantly increase efficiency. See the table below for specific numbers. - Source: Internet
  • Installing a new water heater in your home isn’t cheap, which is why you’re probably taking some time considering how to power your appliance. The first thing to know is that electric heaters are the best option for the environment, and opting for one of these will mean you’re making a more sustainable choice for the planet. Electric water heaters are also more efficient, though the cost of electricity bumps the cost of running past gas alternatives. As we’ve already mentioned, you can also still run your gas heater in a power-out and have one less thing to worry about in a crisis. - Source: Internet
  • Tankless Water Heaters: Tankless water heaters do not store heated water. Instead, water passes through a heat exchanger, providing hot water on demand. A tankless water heater can reduce energy consumption, and since the unit is installed on a wall it frees up floor space – making tankless a great choice for small basements. - Source: Internet
  • When you’re spending so much at once for a hot water heater, the question of longevity is a concern. Fortunately, tank style water heaters generally last eight to 12 years on average – depending on if you have hard water in your area and perform regular maintenance to keep the heater running at peak efficiency. We found through our research and discussions with plumbing professionals that you can expect a new water heater to last for about 10 years. Setting aside a little money every year to help offset the cost for when you do have to replace it can help reduce the stress of forking over a chunk of change you weren’t expecting to spend. - Source: Internet
  • The ability of a water heater to meet peak demands for hot water is indicated by its first-hour rating. This rating accounts for the effects of tank size and how quickly cold water is heated. In some cases, a water heater with a small tank but powerful burner can have a higher first-hour rating than one with a large tank and less powerful burner. Ask appliance dealers for the first-hour ratings of appliances they sell or check the manufacturer’s literature. - Source: Internet
  • You can estimate your new electric or gas water heater’s annual and lifetime energy costs with this calculator from the Federal Energy Management Program (opens in new tab) (FEMP). It also compares your estimates with those of base models, FEMP recommendations and the most efficient models in the industry. This calculator can help you decide if a more efficient model is worth the extra cost over its lifetime. - Source: Internet
  • — In rare cases installing a tankless heater requires a carpenter to do drywall work. According to Fixr, this should cost between $100-300 at an average carpentry rate of $75 per hour. Supplies and parts — Your plumber may need to use connectors, fittings, mounting hardware, and other parts during the install. According to Homewyse, this should cost about $50. - Source: Internet
  • Explore the options and decide what type of water heater you want — gas or electric, storage or demand, stand-alone or integrated with your heating system, etc. Figure out the proper size for your household, not just in terms of gallon capacity, but first-hour rating as well. This is particularly important with newer energy-efficient technologies. (See “Sizing Your Water Heater.”) - Source: Internet
  • Tankless water heaters can be purchased to heat a single sink, tub or shower (known as point-of-use tankless water heaters) – or to heat water for the whole house. The purchase price for a tankless water heater can be as low as $150 or as high as $2,500 or more. Solar-powered tankless water heaters are the most expensive, costing as much as $6,000. - Source: Internet

  • Installation costs typically include labor, supplies and water heater removal. You can expect to pay between $300 and $500 to have an installer swap out your old water heater for a newer model, though this may increase or decrease based on where you live. However, if you’re changing the type of water heater in your home, you can expect to pay up to $1,500, sometimes more, to upgrade your home’s electrical or natural gas connections appropriately. Make sure to get quotes from three or four local plumbers in order to find the best price. - Source: Internet
  • Evaluate the water heater’s energy performance before buying. Gas- and oil-fired water heaters (tanked and tankless) use “energy factor” or EF. The higher the EF, the higher the efficiency. - Source: Internet
  • Flow rate (GPM) — Tankless hot water heaters heat water instantaneously (which is why they are also referred to as on-demand hot water heaters). The flow rate measures the maximum amount of water they can heat on demand. Temperature Rise (ΔT) — The temperature of the incoming cold water — referred to as the groundwater temperature — determines how much energy will be needed to heat the water. Temperature rise is measured by taking the desired hot water temperature minus the incoming ground water temperature (which will vary by time of year and the place you live). - Source: Internet
  • Water heaters can be a costly investment for home owners that you’ll be living with for over a decade. That’s why when it’s time to equip your new home, or replace your old water heater it’s important to consider cost, efficiency, and longevity of your new water heater. We’ve put together this comparison of storage water heaters vs tankless water heaters to help homeowners and contractors decide on the type of water heater that’s best for you. We’ll examine the pros and cons of tankless and traditional water heaters so you can make an informed decision. - Source: Internet
  • Electric or gas? Which is better? In reality, there is no single answer to this question. What is better for one household, might not be the best for another. The decision to select an electric or gas tankless water heater should be made with the homeowner’s or business’ individual circumstances in mind. The following factors all play a role in choosing what type of tankless water heater is best for your needs: - Source: Internet
  • — Depending on your home, a tankless water heater may cost more to install. That’s because most homes in America have conventional electric water heaters and switching requires more labor and parts than simply replacing an old unit with the same type of heater. High GPM capacity models are expensive — Tankless hot water heaters are best if you don’t need to use a lot of hot water simultaneously. You can buy models that offer as much as 12 GPMs (far more than enough for a big family all showering at once), but they are expensive (~$2,500). - Source: Internet

  • A solar hot water system is more expensive to buy and install, but the running costs can be significantly lower. Solar hot water systems can be boosted with either gas or electricity. In Victoria, solar water systems can rely quite heavily on their boosting system, particularly in winter months. Solar water systems do not generate electricity and take up space on your roof which can limit the space available for Solar PV systems. - Source: Internet
  • So there’s a good chance that you could buy a $350 tankless water heater and pay a plumber $400 to install the unit (a total installed cost of $750). This is about the same cost as installing a conventional 40 gallon hot water heater. It is about $500 less than installing a heat pump water heater. - Source: Internet
  • Consumers often choose to use the same energy source for water heaters that we use for space heating. This is a preference, not a requirement. It pays to compare water heaters by the fuel types available in your area. - Source: Internet
  • If you’re looking for a cheap, mid-level water heater brand, then Rheem is a great choice, featuring gas, electric, tankless, solar and hybrid options.

  • As I write this, I am sitting in a 1,100 square foot home (half the average). My last apartment was 800 square feet. I live with one other person who takes showers two hours earlier than me each morning. We run the dishwasher and laundry at night (not while we shower). That means the GPMs we would need are going to be far lower than the average, which means the cost of a tankless water heater would be much lower. - Source: Internet
  • Many energy-efficient water heaters are gas-powered. However, you could get electric options that may be more efficient, according to Bob Vila. Energy-efficient electric water heaters could cost more than their gas counterparts initially. In order to make the right choice and avoid any additional costs, make sure you look at prices when you’re evaluating electric vs. gas water heaters. - Source: Internet
  • North Carolina’s Consumer Council says that any energy savings from purchasing an electric water heater is likely eclipsed by a gas water heater in the long run because of gas prices. Homes that lack a gas hookup, or buildings that are electric-only can drive people to use an electric water heater (vs. gas) due to the convenience of the installation and operation. - Source: Internet
  • Indirect water heaters, when used in combination with new high-efficiency boilers, are usually the least expensive way to provide hot water (see “Comparing the True Costs of Water Heaters”). These systems can be purchased in an integrated form, incorporating the boiler and water heater with controls, or as separate components. Gas-, oil-, and propane-fired systems are available. Any form of hydronic space heating — hydronic baseboards, radiators, or radiant heat — can be provided by boiler systems. - Source: Internet
  • If you’re thinking of going for an electric tankless model, consider this: while they don’t have the methane problem, they use three times as much energy as heat pump water heaters, costing you dearly, and they are arguably no better for the climate than gas water heaters. This is because they draw electricity, a lot of it, exactly when users need hot water, which tends to coincide with times of higher power demand on the grid and emissions from power plants. This makes it more difficult to transition the grid to 100 percent clean energy to clean our air and stave off the worst of the climate crisis. We need efficient and flexible heat pump water heaters, not inefficient and inflexible electric tankless models. - Source: Internet
  • High efficiency gas hot water systems have typically been considered the most economical type of water heater when operated on natural gas. Recent advancements in heat-pump technology mean that this is no longer the case. If you have a conventional gas or electric hot water system that needs replacing, you should consider a heat-pump water heater over a more efficient gas or solar hot water system. - Source: Internet
  • There’s no guarantee that gas prices will stay lower than electricity prices. In fact, most economists agree that gas prices will likely increase in the future. Electric Tankless Water Heater Electricity prices fluctuate less than gas prices. - Source: Internet
  • According to the EnergyRates website, natural gas is usually less expensive than electricity. Deciding between an electric vs. gas water heater is more a question of economics than preference. Bob Vila says that while electric water heaters may cost more to run than gas-powered water heaters, they’re less expensive to purchase because they do not require the complicated gas hookup, installation fees, and open flame heating mechanism of a gas water heater. - Source: Internet
  • However, that’s not to say tankless water heaters are the best solution for everyone. Storage tank water heaters have a lower initial cost, and purchasing one that’s insulated can reduce standby heat loss and operating costs. Depending on the household’s usage of hot water, storage tank models could be a more cost effective option. - Source: Internet
  • This water heater’s stainless steel design means that it’s actually a much lighter option than others of the same size, and will not build up limescale as much as other heaters. This means that it should last much longer than other offerings. Meanwhile, the temperature can easily be controlled with the adjustable thermostat on the side, so that you can always make sure that your house is at the perfect temperature for you and your family. - Source: Internet
  • For most homeowners and businesses, their water usage patterns and needs will not affect their choice of what type of water heater they should select. Electric tankless water heaters can provide from 3 to 8 gallons per minute of shower temperature water depending on the model selected and climate (incoming water temperature). This is enough to meet the needs of most families. There are some gas tankless heaters on the market that are capable of larger demands in the case that unusually high flows are required. - Source: Internet
  • Tankless water heaters come in both gas and electric options, so you don’t have to decide between a gas (vs. an electric) water heater if you already have a preferred type. Tankless water heaters work by drawing in cold water when you turn the tap on, instantly heating the water as it passes through a gas burner or electric element. - Source: Internet

  • On average, you can expect to spend between $700 and $2,000 to get a new water heater installed in your home. Without installation, electric water heaters usually cost between $300 and $700. Similarly, gas water heaters cost between $400 and $1,000. However, a heater’s cost depends largely on the water heater brand, tank size and its efficiency rating. - Source: Internet
  • Storage tank water heaters are commonly found in most homes. Their components are an insulated tank, typically holding 30-50 gallons of water, to heat and store the water until it’s needed. A pipe emerges from the top to deliver hot water to its destination, kitchen, bathroom, or other sinks. - Source: Internet
  • Storage water heaters will lose less heat if they are located in a relatively warm area. Also try to minimize the length of piping runs to your kitchen and bathrooms. The best location is a centralized one, not too far from any of your hot water taps. - Source: Internet
  • That’s why many people, according to HouseLogic, install multiple tankless water heaters in their homes, or a tankless water heater for each large appliance or bathroom. This way you won’t eclipse your tankless water heater’s abilities, but be prepared for a substantial initial cost when purchasing and installing each tankless heater. However, since a tankless heater can last twice as long as a traditional water heater, and since they have easily replaceable parts, this potentially offsets their initial price. - Source: Internet
  • Typically, there are storage-tank water heaters that use either natural gas or electricity for their fuel. Natural gas storage-tank water heaters use almost 50 percent less energy, costing less to operate, than the electric variety. However, they cost a bit more than electric models. They also feature a temperature and pressure-release valve that opens when either temperature or pressure exceeds preset levels. - Source: Internet
