We stand behind our work. If you're not satisfied, we'll make it right.
We measure the heat load room by room and check how the existing zones are laid out before specifying a unit.
Equipment, labour, permits, and disposal in one number. Financing available.
The existing boiler is drained, disconnected, and removed, and the system is flushed to clear sediment.
New boiler mounted, near-boiler piping built to the manufacturer's spec, circulators and zone valves fitted, expansion tank sized.
We purge air, set the operating curve, test safeties, and balance the zones so every room reaches temperature.
A condensing boiler runs at higher efficiency and needs different venting and a condensate drain.
Each additional zone adds a circulator or valve, wiring, and controls.
Boiler swaps often need the piping rebuilt to meet the new unit's flow requirements. This is a large share of the labour.
A combi unit handles domestic hot water as well, which changes the plumbing and removes the separate water heater.
Old cast iron radiators and in-floor loops sometimes need flushing or valve replacement.
Boiler installation starts at $15,000 + HST. Boilers vary more than furnaces because near-boiler piping, zoning, and whether you want a combi unit all change the scope significantly.
Most replacements run two to three days. Rebuilding the near-boiler piping and purging a multi-zone system is what takes the time.
A combi boiler heats your home and produces domestic hot water on demand from the same unit, so you no longer need a separate water heater. A heat-only boiler handles space heating alone.
They are different systems rather than better or worse. Hydronic heat is even and quiet, and a condensing boiler reaches high efficiency, but a boiler cannot deliver central air conditioning through the same distribution.
Usually yes. Existing radiators and in-floor loops can normally be reused with a new boiler, provided they are in good condition and the system is flushed properly.
Yes, 0% financing is available with payments from $42/mo.
