Williamson-Thermoflo combi install done right — in Chilliwack

Williamson-Thermoflo manufactures gas-fired residential boilers in the United States, spanning traditional cast-iron water and steam units to modern wall-mounted stainless-steel condensing models. The lineup covers atmospheric cast-iron designs for chimney-vented homes as well as high-efficiency FreeStyle condensing boilers available in heat-only and combi configurations.

Local note: Chilliwack's dairy farms, rural acreages, and growing Sardis and Promontory subdivisions call for both high-BTU systems for outbuildings and efficient combis for new townhomes. Propane sizing and conversions are common on Fraser Valley acreage. We regularly service Williamson-Thermoflo boilers across Sardis, Vedder Crossing, Promontory, Yarrow, Rosedale, Greendale and the rest of Chilliwack.
