Top 5 Best Residential Boilers in Canada
2024-03-04
These are the best residential boilers available in Canada, according to Afterglow.
A lot of factors make up a truly good boiler — efficiency, durability, longevity, and control systems. But in the end, this is the machine that needs to keep you warm through those long Canadian winters.
The boilers below fall in the mid to high price range. But buyer beware: some cheaper models may boast high efficiency ratings, but they often suffer breakdowns after only a few years of service. We've seen it too many times.
Top honours go to the Canadian-made IBC SL20-115 G2 for its rugged stainless steel heat exchanger, smart controls, and all-around performance.
