Important: Four of these heaters require hardwired 240V installation, and one requires a specific dedicated 250V/30A receptacle. Do not assume an existing dryer, welder or EV-charging circuit can be repurposed — have a qualified electrician confirm panel capacity and circuit design first.
The Dr. Infrared Heater DR-988 is our best overall choice when the garage has — or can be equipped with — a dedicated NEMA 6-30R receptacle. For a fixed installation, choose the DR-966; larger garages should consider the DR-975 or DR-910F only after an electrician confirms the circuit can support the load.
Best Electric Garage Heaters in Canada at a Glance
| Model | Best for | Output | Installation |
|---|---|---|---|
| Dr. Infrared DR-988 | Best overall | 5,600W | NEMA 6-30P plug |
| Dr. Infrared DR-966 | Best permanent 6,000W | 3,000/6,000W | Hardwired |
| Dr. Infrared DR-975 | Larger garage | 7,500W | Hardwired |
| Comfort Zone CZ220 | Lower-output ceiling | 5,000W | Hardwired |
| Dr. Infrared DR-910F | High-output workshop | 10,000W | Hardwired |
1. Dr. Infrared Heater DR-988 — Best Overall
Produces 5,600W (approximately 19,100 BTU/h) through a six-foot cord with a NEMA 6-30P plug, requiring a dedicated NEMA 6-30R 250V/30A receptacle — not a standard household outlet. Adjustable thermostat approximately 3°C to 45°C, ON/AUTO fan modes and overheat cut-off. Manufacturer states UL and cUL listed.
Best fit: a one- or two-car garage that has, or will have, the exact receptacle professionally installed. Check price on Amazon.ca
2. Dr. Infrared Heater DR-966 — Best Permanent 6,000W Heater
240V hardwired wall or ceiling unit with 3,000W and 6,000W settings (up to 20,472 BTU/h), thermostat approximately 3°C to 40°C and five adjustable louvers. No power cord included; circuit design should be left to a qualified electrical contractor.
Best fit: a fixed heater in a typical insulated garage where adjustable output matters more than a remote. Check price on Amazon.ca
3. Dr. Infrared Heater DR-975 — Best for a Larger Garage
4,700W and 7,500W settings (up to ~25,600 BTU/h), remote-controlled thermostat (10°C–29°C) and timer. Hardwired 240V; the installer determines the complete circuit design under applicable code.
Best fit: larger two-car garages or taller ceilings needing more than 5,000–6,000W. Check price on Amazon.ca
4. Comfort Zone CZ220 — Best Lower-Output Ceiling Heater
5,000W ceiling-mounted unit (up to ~17,065 BTU/h) with fan-forced air, adjustable louvers and overheat sensor. Manufacturer describes it as ETL listed — inspect the delivered heater for a recognized Canadian mark such as cETL before installation.
Best fit: a smaller insulated garage with simple physical controls. Check price on Amazon.ca
5. Dr. Infrared Heater DR-910F — Best High-Output Workshop Option
10,000W (approximately 34,120 BTU/h), remote-controlled thermostat and timer. At 10kW, continuous electrical demand is approximately 41.7A at 240V — a qualified contractor must confirm panel capacity and whether other major loads can operate simultaneously.
Best fit: a large garage or workshop with confirmed electrical capacity. Check price on Amazon.ca
How Much Heater Does a Canadian Garage Need?
Heat loss depends on local winter design temperature, insulation, garage-door construction, air leakage, ceiling height and desired temperature — not floor area alone. Electric resistance heat converts at approximately 1 watt = 3.412 BTU/h. A heat-loss assessment from an HVAC professional is more reliable than a square-foot rule.
120V vs 240V Garage Heaters
A typical 120V portable heater tops out around 1,500W (~5,100 BTU/h) — useful for one workbench area but unlikely to heat a cold two-car garage evenly. A 240V heater can deliver 5,000–10,000W through a dedicated circuit, but installation becomes part of the purchase: panel capacity, existing EV/dryer/range loads, circuit design and mounting clearances all need professional review.
Garage-Heater Safety in Canada
Verify a recognized mark on the actual heater and packaging (CSA, cUL or cETL) — a CE or FCC mark is not a substitute. Keep combustible materials at least the manufacturer's specified clearance, and never operate electrical equipment where flammable vapours from gasoline, propane or solvents are present unless specifically approved for that environment.
Can a Portable Power Station Run a Garage Heater?
Not for a practical length of time. A 5,000W heater exceeds the continuous output of most portable power stations, and even a capable battery system would consume roughly 5,000Wh per hour of full output — substantially more than a typical 1,000–2,000Wh station stores. See our power-station sizing guide for realistic backup-power planning.
Frequently Asked Questions
What is the best wattage for a two-car garage in Canada?
Many product lines position 5,000–7,500W heaters for two-car garages, but a heat-loss assessment is more reliable than a square-foot rule.
Is a plug-in 240V heater easier than a hardwired model?
It is easier to reposition, but it still requires the exact dedicated receptacle specified by the manufacturer.
Can I use my dryer or EV-charger outlet?
Do not assume so. Receptacle type, circuit rating and simultaneous loads must be evaluated by a qualified electrical contractor.
Bottom Line
The DR-988 is the best overall choice with the correct dedicated receptacle. Choose the DR-966 for a permanent 6,000W installation, the DR-975 for a larger heat load, and the DR-910F only after a professional confirms 10,000W capacity. The Comfort Zone CZ220 offers a simpler 5,000W alternative. Treat the heater, circuit and building envelope as one system.
