High-efficiency condensing boilers and radiant heating, expertly installed and serviced for older homes across Marin and Sonoma County.
A condensing boiler pulls extra heat out of the exhaust by condensing its water vapor, reaching well over 90% efficiency, but only when the controls and your radiant loops let the return water run cool enough. We commission every install so it truly condenses instead of behaving like a standard boiler.
Usually yes. Many North Bay homes with radiant floors or cast-iron radiators are good candidates, and we evaluate your piping, emitters, and venting before recommending the right modulating condensing boiler for the house.
Yes. As licensed (#501853) hydronic specialists since 1986, our trucks carry the common condensing-boiler and radiant parts, so most cold-weather repairs from Santa Rosa to San Rafael get heat back the same day.
Once a year, ideally before heating season. Annual service keeps the heat exchanger, condensate drain, combustion, and radiant controls in good shape, protects the warranty, and catches small issues before a winter no-heat call.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
