How do Tankless Gas Water Heaters work?
Gas Tankless Water Heaters work by heating water ‘on demand’ or ‘instantaneously’. The unit sits idle (on standby) using only minimal power and not consuming any gas. When a hot tap is opened, sensors are triggered within the unit, causing it to ignite, starting the flow of gas to the main burner which creates combustion of a very high-output gas flame. As cold water travels through the GWH, it circulates around the gas burner inside a copper coil – known as a Heat Exchanger. The speed at which the water travels through the GWH determines the speed of hot water delivered (flow rate).
The faster the water travels through the unit, the lower the temperature output. The slower the water travels in the GWH, the higher the output temperature. Computer-controlled units such as Paloma GWH’s utilise sensors and solenoid valves to continually adjust gas and water flows to ensure water temperatures are consistent and energy usage is at its most efficient. The tankless water heater will produce an unlimited quantity of hot water, as long as power and gas are uninterrupted.
‘Tankless’ means that the water is not stored and kept hot in a ‘tank’ until you need it, wasting energy. Tankless heaters heat the water as it is needed, giving the impression of ‘instant hot water’. Using a tankless hot water heater means your hot water never runs out!
