Heated Garages in Calgary: The Complete Guide
In a city where January mornings hit -30°C, a heated garage isn’t a luxury — it’s genuinely life-changing. Here’s everything you need to know.
Heating System Options
1. In-Floor Radiant Heating (Best Option)
PEX tubing embedded in the concrete slab, heated by a boiler or electric system.
- Pros: Most comfortable, even heat, melts snow off vehicles, quiet
- Cons: Highest upfront cost, slow to respond to temperature changes
- Cost: $12,000 – $20,000 for a typical 2-car garage
2. Forced Air Heater
Natural gas unit heater mounted near the ceiling.
- Pros: Heats quickly, moderate cost, proven technology
- Cons: Noisy, heats air (not floor), uneven temperature
- Cost: $3,000 – $6,000 installed
3. Radiant Tube Heater
Long overhead tube that radiates heat downward.
- Pros: Efficient, good for workshops
- Cons: Hot spots, overhead clearance required
- Cost: $2,500 – $5,000
4. Electric Baseboard
Simple electric heaters along walls.
- Pros: Low upfront cost, easy install
- Cons: High operating cost, limited output
- Cost: $800 – $2,000
Insulation Requirements
A heated garage needs proper insulation or you’re just heating the atmosphere:
- Walls: R-20 minimum (spray foam or batt + vapour barrier)
- Ceiling: R-40 minimum
- Slab: R-10 under the slab for in-floor heat
- Garage door: R-16 minimum insulated door with good seals
