Like the Monitor Tankless Water Heater, the Rinnai model only heats water when it is needed and provides you with continuous hot water. When you turn your faucet on, the Rinnai begins heating the water as it passes through its copper heat exchanger. In addition to saving you money and energy, the Rinnai heater is good for the environment. It produces less CO2 and NOx than gas or electric tank water heaters. The Rinnai system also includes digital controllers that enable you to control the output water temperature-maximizing your comfort and safety. The Rinnai has a sleek, contemporary design that you don’t need to hide, allowing you to position your heater wherever best suits your needs. And the system is available in both interior and exterior models. The average Rinnai heater has a life span of 20 years or more in a residential application, and comes with a 12-year limited warranty.
