When integrated with a Rinnai Tankless Water Heater or Condensing Gas Boiler, the Rinnai Hydronic Air Handler offers hydronic solutions for comfortable space heating as well as a continuous supply of domestic hot water. This integrated solution is ideal for both new construction and retrofit applications.

Rinnai Hydronic Air Handler models with or without an integrated pump can be customized to specific installation needs for maximum efficiency and comfort. An internal pump allows integration with Rinnai Tankless Water Heaters to simultaneously provide home heat and Domestic Hot Water. The no-pump models can be integrated with combi boilers offering hot water to the home while isolating the space-heating loop from the DHW loop.
