Experience a never-ending supply of hot water and a more comfortable
way to heat your home – all made possible by the reliable, efficient Rinnai
tankless water heater. With Rinnai’s Tankless Heating System, your Rinnai
tankless water heater is paired with the new and improved Rinnai hydronic
furnace to deliver comfortable, efficient heat to your entire home.
Rinnai — The First Tankless Company to Bring You Endless Hot Water
and a Hydronic Furnace in One Package
•
Rinnai Gives You a Matched Component System. Rinnai offers a complete
home heating system designed specifically for use with a Rinnai tankless
water heater.
•
Easy, Flexible Installation Saves You Money & Hassles.
The hydronic furnace requires no venting or gas lines so you can place it
in a closet, crawl space, attic or basement.
•
You Enjoy Comfortable Hydronic Heat. Using a hot-water coil,
your home’s air is less dry than with a typical gas furnace.
•
Heat Your Air as Efficiently as Your Water. The Rinnai Tankless Heating
System delivers the same efficiency as your Rinnai tankless water heater.
• Domestic Hot Water Priority System – A flow sensor (included with
each furnace) interfaces with the control board to suspend operation
during periods of heavy household hot water use, thus preventing the unit
from blowing cold air and improving pump reliability.

NOTE: The Rinnai hydronic furnace was designed specifi cally to accommodate most
brands of evaporator coils. This allows you and your HVAC professional to use the
cooling equipment of your choice. The Rinnai hydronic furnace can be used as the
back-up or cold-weather heat source in “dual fuel” or “hybrid systems” with heat
pumps. This may provide the most effi cient way to heat your home.
Be sure to have a licensed, trained professional size your Rinnai tankless water heater
and hydronic furnace to suit your home’s specifi c hot water and hot air requirements.
