How Do Continuous Flow Hot Water Systems Work

Continuous hot water systems heat the water as it is needed by passing cold water through a heat exchanger device, igniting a gas burner or switching on an electric element heating the water. Continuous hot water systems are very economical because water is only heated as required which means there is no additional cost to ‘storing’ hot water. 

When a hot water tap is turned on, an electronic sensor starts the heating element. In a continuous flow gas system it triggers an actual burner and in an electric system it triggers an electric heating element. As water passes through the unit, it is heated to the preset temperature and then fed straight to your tap. When the tap is turned off, the unit stops the heating process.
