The most even, silent heat available — no forced air, no dry air, no cold spots. H&C installs and services Rinnai high-efficiency boilers across the GTA.
Hot water radiates evenly from the floor up — no cold spots, no drafts, no dry air. Every room stays at the same temperature without forced-air discomfort.
97%Max AFUE
Lower Heating Costs
Rinnai's condensing technology extracts heat even from exhaust gas. Up to 97% AFUE — virtually no energy is wasted, translating directly into lower gas bills.
25Year Lifespan
20–25 Year Lifespan
Boilers have fewer moving parts than furnaces. A well-maintained Rinnai boiler lasts 20–25 years — well beyond the life of a typical forced-air system.
Time to Upgrade?
Still Running an Old Conventional Boiler? Here's What You're Leaving on the Table.
Most GTA homes with boilers are running cast iron units from the 1980s or 90s — operating at 60–70% efficiency. A Rinnai condensing boiler changes everything.

"H&C replaced our 30-year-old cast iron boiler with a Rinnai i-Series. The difference is night and day — our gas bill dropped by about a third and every room heats evenly now. Should have done this years ago."

"Our boiler broke down on Christmas Eve. H&C had a technician out within two hours and got our heat back on the same night. They then installed a new Rinnai combi-boiler the following week. Incredible service."

"Our baseboard heating was always uneven with the old boiler. H&C installed a Rinnai condensing unit and rebalanced the zones — every room is comfortable now. They also helped us get an Enbridge rebate."
