The Rinnai tankless water heater is a more efficient way to heat water. It heats water quickly and delivers an endless supply of hot water for as long as you need it. With the Rinnai tankless water heater, you only pay to heat water when you need it and for as long as you want it.

Did you know? Rinnai tankless water heaters…

  • Produce and supply endless streams of hot water to multiple outlets simultaneously without any fluctuation in temperature
  •  Are up to 30 percent more energy efficient than a traditional natural gas water heater and up to 50 percent more efficient than an electric water heater
  • Shut-off automatically when the water supply is closed, providing users with significant energy savings – in turn saving money on their utility bills
  • Are compact wall mounted units with a life expectancy of 20 years, whereas hot water tanks require about 16 square feet of floor space and usually last around 10 years

  1. A hot water tap is opened such as a kitchen / bath faucet, shower, tub or washing machine
  2. The water flow through the Rinnai tankless water heater detects the call for hot water
  3. The water flow turbine sends a signal to the control board which looks at multiple factors:
    1. Incoming water temperature
    2. Desired water temperature as set on the temperature controller
    3. Calculated difference between the two temperatures
  4. Depending on the calculated incoming and desired water temperatures, the gas flow into the burner assembly is modulated
  5. The electronic ignition sequence begins
  6. Water is heated to the desired temperature as it circulates through the copper heat exchanger providing endless hot water
  7. When the hot water tap is turned off, the tankless water heater sequentially shuts down and is placed in a standby mode pending the next call for hot water
