Unlike old technology water tanks that heat and reheat the same water 24 hours a day, Rinnai Continuum is more efficient because it only heats water when it is needed. When a water source is opened, Rinnai Continuum senses the demand for hot water flow and starts the heating process. The water flows through a heat exchanger and is heated to the designated temperature set by the user.
The Rinnai Continuum system uses the feedback from a water flow sensor to adjust the fully modulating gas valve, giving users a consistent water temperature for any duration. When the water source tap is closed, Rinnai Continuum automatically shuts off until hot water is demanded again, providing significant energy cost savings up to 70% on monthly heating and power bills. No standing pilot light means no standby losses.
