Boiler Installation in Georgetown

$6,800 – $18,500 depending on type, modulation, and hydronic complexity. Most Georgetown radiator homes upgrading to a condensing combi land at $9,500 – $14,500. Free on-site load calc quotes the exact number.

Condensing every time unless the chimney/venting situation forces non-condensing. Condensing boilers operate at 95+ AFUE (vs 80% non-condensing), with side-wall PVC venting eliminating chimney issues. Fuel savings $300 – $600/yr typical Georgetown. Payback 5-9 years on the upgrade premium.

Combi: smaller homes, ≤ 2.5 baths, no simultaneous high DHW demand. Heat-only + separate tankless: larger homes, 3+ baths, multiple simultaneous hot water uses. Both are correct choices for the right home.

Yes if they're sound (no leaks, valves work). Old cast-iron radiators are excellent heat emitters and a strong match for modern condensing boilers. We pressure-test the radiator loop before commissioning the new boiler. Old radiators that don't pass pressure test get individual repair / replacement quoted separately.

Yes — adding radiant floor zone is a common scope expansion. Basement slab + bathroom floor are typical. $2,500 – $6,500 added per zone. Best paired with the boiler install since the manifold and boiler are sized together.

2-3 days for condensing combi swap with chimney/venting changes. 1-2 days for like-for-like heat-only swap. 4-7 days if hydronic loop reconfiguration. Heat is off during the work; we coordinate to avoid extreme cold periods if possible.

Indoor boiler installs are not gas-line work — minimal FIFA impact. Downtown Georgetown postal codes may have minor Enbridge inspector scheduling delays late June through July; we plan a 2-3 day buffer in those zones. Outside downtown core: no impact.

Honeywell Aquatrol — best for simple multi-zone hydronic. Tekmar 5xx-Series — best for outdoor reset (boiler temp adjusts based on outside temp; saves 10-15% fuel). Ecobee — works but not optimized for hydronic (no outdoor reset). We default to Tekmar for premium, Honeywell for workhorse.

20-30 years for premium condensing (Viessmann Vitodens, Triangle Tube). 15-22 years for workhorse (Navien, IBC, NTI). 12-18 years for value (Lochinvar). Annual servicing critical — schedule before each heating season.

10-year parts on most premium boilers (Viessmann 12-year HX, Navien 10-year HX). 3-year RenoHouse labour warranty (longer than our furnace warranty given hydronic system complexity). Lifetime warranty on the venting and gas piping installation.

Heat pumps deliver air at 38-43°C; radiators emit heat based on water temp 50-80°C. Air-to-water heat pumps (Lambda, Mitsubishi, NIBE) DO exist for radiator retrofits but cost $25K-$45K+ installed and need radiator replacement with low-temp emitters. For most radiator homes, condensing boiler is still the right answer in 2026 — heat pump retrofit becomes economic when fuel prices double from current. We model both at the consultation.
