Instant Hot Water System Experts

Instant hot water systems, also known as continuous flow hot water systems, operate by filtering water through a heat exchanger before it’s sent directly to the tap. Your continuous flow system will only turn on when your hot water tap is turned on. This is one of the main benefits of these systems and why they are so common. Water is sent through a heat exchanger, which transfers heat from the burner into the water.

Hot, steamy water is then delivered straight to your faucets. As soon as the hot tap is turned off, the burner also switches off and water is no longer pumped through the unit. Because water needs to be slowed down in order to properly heat it as it goes through the heat exchanger, you won't receive mains pressure hot water with a continuous flow unit. This means that multiple open taps will result in decreased water temperature and amount. This is really the only downside to one of these hot water systems.

Instant hot water systems can be installed in gas or electric models. Depending on the fuel source and the model you’re able to choose, as well as your living situation, it could be cheaper to run and more energy and water efficient than a storage appliance. Gas has mostly always been the better choice, with some states such as SA phasing out the installation of new electric hot water storage units. However, many manufacturers are now producing highly efficient electric models as well.
