Heater Size and BTU Output

Garage heaters come in various sizes. The right BTU output depends on your space:

• Small garages (1-car): 30,000-50,000 BTU
• Medium garages (2-car): 50,000-75,000 BTU
• Large garages (3+ cars): 75,000-100,000 BTU

For example, the Reddy Heater 150,000 BTU works well for oversized spaces. But smaller garages need less power.

Calculating Your Needs

Use this simple formula:

BTU = (Garage Length x Width x Height x 0.133) + (Window BTU Loss)

Ventilation Requirements

Proper ventilation prevents dangerous gas buildup. Consider these options:

According to The Wood Whisperer, sealed combustion chambers work best for dusty environments.

Safety Features to Demand

Never compromise on these safety elements:

• Tip-over switch
• Oxygen depletion sensor
• Overheat protection
• Flame failure device

The best built-in gas heaters include all these protections. Portable models should too.

Fuel Type Options

Gas heaters use different fuel sources:

Natural Gas

Requires permanent gas line. Lowest operating cost.

Propane

Uses portable tanks. More expensive than natural gas.

Dual Fuel

Works with both. Offers flexibility but costs more.

Installation Factors

Consider these installation requirements:

• Clearance from walls/ceilings
• Gas line access
• Electrical needs
• Mounting options

As noted in electrical forums, some units need dedicated circuits.

Maintenance Needs

Regular maintenance keeps heaters running safely:

1. Clean burners monthly
2. Check gas connections quarterly
3. Inspect vents annually
4. Replace filters as needed

Proper care extends heater life and prevents hazards.

Cost Considerations

Budget for these expenses:

High-efficiency models cost more upfront but save on fuel.
