John Owens Services has been an authorized Rinnai dealer and installer for Marin and Sonoma County since 1999, and a preferred Rinnai service provider in the area for more than 25 years. Rinnai is the largest gas appliance manufacturer in the world, established in the U.S. since 1974, with more than 30 million tankless water heaters sold worldwide.

We only recommend products we would put in our own homes, and Rinnai has earned that trust. Whether you are choosing a new system or keeping an existing one running, we handle installation, repair, and maintenance the John Owens Way: maintain and repair first, and replace only when it is the right call for your home.

Rinnai Systems We Install and Service

Rinnai’s lineup covers most of the ways a Marin or Sonoma County home heats water and living space. We help you match the right unit to your house and then stand behind the install:

Tankless water heaters — among the most trusted tankless units on the market, delivering hot water on demand without a storage tank.Heat pump water heaters — a newer, high-efficiency option that lowers your carbon footprint and your home’s utility bills.Boilers — used for radiant heating, and for domestic hot water as well when the unit is a Combi boiler.Combi and Demand Duo systems — Combi units cover both heating and hot water, while the Demand Duo is built for larger applications that need more capacity.

Whether you choose a Rinnai boiler, tankless, Combi, heat pump, or Demand Duo, you will have a well-engineered water heating system behind it.

Authorized Rinnai Dealer and Installer

John Owens Services is proud to be an authorized Rinnai dealer and installer. For over 25 years we have been consistently impressed with the quality of their tankless units, and the lineup has only gotten stronger with additions like the Demand Duo for larger applications and a high-efficiency heat pump water heater.

We can handle the install and any repairs for your unit, whether it is under warranty or not. Because we install these systems every week, our team knows them inside and out and can diagnose problems quickly.
