High-efficiency condensing boilers and radiant heating, expertly installed and serviced for older homes across Marin and Sonoma County.
From the foggy hillsides of Mill Valley and Tiburon to the cool valley mornings around Sebastopol, Glen Ellen, and the Town of Sonoma, a lot of North Bay homes were built for hydronic heat, with radiant floors and cast-iron radiators fed by a boiler in the garage or basement. The trouble is that many of those boilers date to a different era and oversized, atmospheric units that vent good money up the flue every winter. John Owens Services has rebuilt, repaired, and replaced these systems since 1986, dialing in a modern condensing boiler so it actually runs in condensing mode and your radiant heat warms evenly instead of in fits and starts.
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.
