Hybrid Tank-Tankless Water Heater

The Rinnai RH180 Hybrid Tank-Tankless Water Heater makes life simpler by giving you more hot water to meet your daily hot water needs. Without even realizing it, many of us fall into a routine of planning our lives around hot water. Baths, showers, laundry and running the dishwasher become scheduled events based on hot water availability, instead of when we really want it.

In fact, hot water usage becomes such a habit over the years that we just accept it as part of life. But it doesn’t have to be. The innovative design of the Rinnai RH180 Hybrid Tank-Tankless Water Heater combines the on-demand heating technology of a tankless water heater with an efficient storage tank. The result? The hot water you need flows right into your daily schedule. It’s that simple.

on-demand tankless system with an ample 40-gallon storage tank. By design, the system has a large capacity of hot water as well as technology to help maintain and quickly replenish the hot water supply.
