• Tankless water heaters — also known as demand-type, on-demand or instantaneous water heaters — heat water directly, without the need to store water. A tankless heater has a flow sensing device that is activated whenever a hot water tap is opened. The unit then heats the water using either a gas burner or an electric element and directs the water wherever it’s needed in your home. Since there’s no tank that must be replenished, you don’t have to worry about running out of hot water. Once you close the hot water tap, the unit senses that the flow of water has stopped and shuts off the heating element. - Source: Internet
• If you have a pressurised cylinder, you’ll need to turn off the stop valve or isolation valve on the cold feed pipe. You can turn off the mains stopcock if you can’t find this.
