Rinnai R94 system is more energy efficient than the traditional tank water heater, because it only heats water when it is needed. Rinnai senses the demand for hot water flow when a water source is opened and initiates the heating process instantly. The water runs through a heat exchanger and is heated to the chosen temperature set by the user.
The Rinnai R94Lsi gas system takes all alerts from a water flow sensor to regulate the fully modulating gas valve, ensuring a constant water temperature for any desired period. The system automatically shuts off when the water source tap is stopped, and resumes when demanded again. This provides significant energy cost reduction. All new Rinnai tankless water heating systems come with a 10-year limited warranty on the heat exchanger and a 5 year-warranty on other parts.
