About Toronto Boiler Installation: 22 Years of TSSA-Licensed Hydronic Work Across Toronto and the GTA

Boilers and hydronic heating are all we do. That focus matters more in Toronto than it would in most North American cities, because a very large share of the housing stock here was built around hot water distribution rather than ductwork. Riverdale, Leslieville, The Annex, Cabbagetown, High Park, The Kingsway: these are neighbourhoods full of cast iron column radiators that are still, mechanically, excellent.

What has changed is the boiler feeding them. Most were replaced once, usually in the 1990s, which puts a very large share of GTA equipment in the 25 to 35 year window right now. That is the work we do most: taking a system that still runs at 60 to 70 percent efficiency and retrofitting a 95%+ AFUE condensing unit onto the existing distribution with the mixing valve, outdoor reset, and return-water temperature protection that make the new boiler actually condense.

The other half of our work is newer. Vaughan, Brampton, Markham, and Richmond Hill subdivisions built from the 1990s onward run wall-mounted combi and condensing units with a 12 to 18 year service life, reaching end of life in waves because whole streets were finished in the same two-year window with identical equipment. Different diagnosis, different parts, same published CAD bands.

We are TSSA G1 and G2 licensed, HRAI contractor members, ESA compliant for electrical hookups, WSIB registered, and carry $2M commercial general liability insurance. We are an ENERGY STAR certified installer, which is what lets us file Enbridge Home Efficiency Rebate Plus and Canada Greener Homes Grant paperwork on your behalf rather than handing you a form and wishing you luck.
