The innovation behind our high-efficiency water heaters provides an endless supply of hot water wherever and whenever it’s needed – even for multiple tasks at the same time. Showers and baths? Laundry and dishes? On-demand heating means hot water is always available, so prioritizing activities and scheduling water use is no longer necessary.
Because they operate on an as-needed basis, Rinnai Tankless Water Heaters can use up to 40 percent* less energy than traditional systems, which helps reduce utility costs. This efficient operation can also contribute to a favorable HERS rating and optimize LEED certification.
On top of efficiency, our tankless water heaters feature a commercial-grade heat exchanger for unparalleled quality, durability and safety. And their compact design offers substantial space savings in the home.
The RH180 Hybrid Tank-Tankless Water Heater harnesses the same on-demand tankless technology coupled with an efficient storage tank to deliver more hot water with less recovery time than a traditional tank. And professionals enjoy time and labor savings with quick and easy installation using standard tank connections.
The flexibility and convenience of endless hot water. The reliability of proven engineering. It’s everything homeowners need to feel comfortable.

RINNAI TANKLESS WATER
How a Rinnai Tankless Water Heater Works
1When the need for hot water arises by turning on a shower, washing machine, dishwasher or faucet, cold water enters the Rinnai Tankless Water Heater from the inlet pipe at the bottom of the unit. The PC board is then signaled to activate the flame igniter or ignition.
2A combustion fan turns on to allow oxygen into the burner to ignite the flame as the gas control valve opens at a low frequency. Once an adequate flame is present the igniter stops sparking — beginning the next sequence of operation in a matter of seconds.
3Water is heated as it passes through the coils of the copper heat exchanger, and exits from the hot water outlet pipe to travel through the pipes of the home or business to the water fixture where hot water is needed. For Condensing models, the water is preheated as it passes through a secondary stainless steel (latent) heat exchanger, capturing any extra heat (or latent heat) before it escapes into the vent system.
4The gas valve and blower automatically adjust the incoming gas and oxygen to meet the water heating demands. If the demand is small, the Rinnai Tankless Water Heater can use a smaller flame and less gas. If the demand is greater, the flame can expand across the width of the entire burner to heat more water. The tankless water heater adjusts as needed to ensure the temperature set point is maintained. A digital controller allows the user to choose his desired temperature.
5As the hot water fixture shuts off, cold water stops entering the tankless water heater and the flame diminishes. The combustion fan continues to operate at a low speed for a short period of time. This allows the exhaust of any leftover combustion gases.
