Williamson-Thermoflo boilers in Vancouver
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: Vancouver's older West Side and East Side homes often have legacy cast-iron boilers and original mid-century hydronic systems. We service both heritage installations and modern condensing combi retrofits across all neighbourhoods.
