Types of Boilers We Install & Service
High-Efficiency Condensing Boilers
Modern condensing technology recovers heat from exhaust gases that conventional boilers waste, achieving up to 98% AFUE. Big savings during Calgary's seven-month heating season.
Conventional Boilers
Traditional atmospheric and power-vent boilers remain a practical choice for many Calgary homes — proven, simple, and cost-effective when condensing isn't a fit.
Combi Boilers
Combination units deliver radiant heating and endless domestic hot water from a single compact appliance. Space-efficient — no separate water heater needed.
Hydronic + Radiant Floor
We design and install hydronic systems including in-floor radiant — the most comfortable heat available, and quiet enough you forget it's running.
Trusted Boiler Brands We Install
Navien
Industry-leading efficiency — Navien condensing boilers reach 95%+ AFUE with stainless steel heat exchangers that resist Calgary's mineral-heavy water. Wall-hung designs save mechanical room space and start dependably even at −35°C.
IBC Technologies
Canadian-engineered boilers built specifically for prairie climates. Premium-grade materials selected to handle Alberta's challenging water chemistry and seasonal temperature swings. Properly maintained IBC systems routinely deliver 20-25 years.
Viessmann
Premium German engineering with stainless steel heat exchangers and modulating burners. The systems we recommend when budget allows for the best long-term efficiency and longevity.
Triangle Tube
American-made stainless steel construction with industry-leading warranties. Particularly strong on combi and indirect-tank pairings for whole-home heating + DHW.
Why Boilers Are a Smart Choice for Calgary Homes
- 01Energy efficiency — high-efficiency models can save 20-40% on heating bills compared to old atmospheric units.
- 02Reliable, even heat through Calgary's coldest cold snaps with no temperature stratification or cold spots.
- 03Whisper-quiet operation — no blower noise, no air rush. Most homeowners forget the system is running.
- 04Better for allergies — no forced air means no recirculating dust, dander, or pollen.
- 05Excellent for zoning — heat only the rooms you're using, with multi-zone valves and individual thermostats.
- 06Long lifespan with proper maintenance — 20-25 years on premium units vs. 15-20 for forced-air furnaces.
Frequently Asked Questions About Calgary Boilers
How much does a new boiler cost in Calgary?
Installation typically ranges from $8,000 to $15,000 depending on unit size, efficiency rating, and any required gas line, venting, or condensate work. Combi boilers and hydronic conversions sit at the higher end. Financing is available through Financeit with flexible monthly payments — we provide a written quote with all-in pricing before any work starts.
What size boiler do I need for my Calgary home?
Sizing depends on square footage, insulation quality, window quality, ceiling heights, and Calgary's −35°C design temperature. We perform a Manual J heat-loss calculation on every install instead of matching the old unit's BTU — old units were often oversized and cost you in efficiency for decades.
How do I know if my boiler needs repair?
Watch for kettling, whistling, or gurgling noises (limescale + air), pressure dropping below 12 PSI, visible water seepage near components, inconsistent room-to-room heating, frequent cycling, climbing gas bills, or display error codes. Yellow burner flames instead of blue indicate dangerous combustion issues — shut the unit down and call us.
When is it time to replace rather than repair?
Replacement makes sense once a boiler reaches 15-20+ years, when repair costs exceed half the replacement value, when AFUE is below 80% (modern units run 95%+), or when visible rust, corrosion, or heat exchanger cracks are present. We'll give you an honest comparison with the numbers — not a sales pitch.
How often should I schedule boiler maintenance?
Once a year, in late summer or early fall before heating season. A real annual service includes heat exchanger inspection + flush, combustion analysis with a calibrated analyzer, safety control checks (pressure relief, low-water cutoff, flame sensor), and gas leak testing on connections.
Are there rebates for high-efficiency boilers in Alberta?
Federal and provincial programs periodically offer incentives — the Canada Greener Homes Grant has historically provided up to $5,000 for qualifying heating upgrades. Eligibility usually requires 95%+ AFUE and professional installation with documentation. Our team stays current on what's available and helps with applications.
What's the difference between a boiler and a water heater?
Boilers heat water that circulates through radiators, baseboards, or in-floor tubing to warm your living spaces — a closed loop. Water heaters provide potable hot water for showers, dishes, and laundry. Combi boilers do both functions from one unit.
Why is my boiler losing pressure?
Persistent pressure loss usually means small leaks at pipe joints, radiator valves, or connections that may not be visible. Other causes: defective pressure relief valves, failed expansion tanks, malfunctioning automatic fill valves, or excessive bleeding from radiators. Rapid pressure drops or pooling water needs immediate professional attention.
Can I convert from forced air to a boiler system?
Yes, but it's a substantial investment — typically $15,000-$30,000 depending on home size and chosen heat distribution (radiators, baseboards, or in-floor radiant). Most Calgary homeowners pursue conversions during major renovations to gain zone control, eliminate allergen circulation, and enjoy quieter, more luxurious heat.
