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.
