Buying Guide For Gas Shop Heaters
BTU Output And Coverage Area
Select a gas heater with the appropriate BTU rating based on your shop’s size. Larger space needs higher BTU output. Measure your garage or workspace square footage and consider insulation quality. For typical garages, units ranging from 40,000 to 80,000 BTU cover most areas effectively. For bigger warehouses, you may require 100,000 BTU or more.
Fuel Type: Natural Gas vs Propane
Natural gas heaters are ideal if you have existing natural gas hookups, offering lower operational fuel cost and a steady supply. Propane heaters provide portability and are good for spaces without natural gas installation but require refilling propane tanks. Some models offer conversion kits for flexibility between fuel types.
Mounting Options And Installation
Consider whether you want wall-mounted, ceiling-mounted, or floor-standing units. Ceiling mounts save floor space and distribute heat more evenly throughout the shop. Check clearance requirements to ensure safety and proper airflow around the heater.
Noise Level
Noise can be a concern, especially in workshops requiring focus. Look for products with quiet burner technologies or quiet operation features to minimize disruption.
Efficiency And Technology
Higher thermal efficiency ratings translate into less fuel waste and cost savings. Infrared technology heats objects directly, which can be more effective in poorly insulated shops. Forced air units circulate warm air quickly, offering fast heat-up times.
Safety Features
Check for temperature limit switches, automatic shut-offs, and proper venting options. Ensure the heater complies with residential or commercial safety certifications.
Additional Accessories
Some heaters include or require accessories like thermostats, hoses, regulators, and mounting brackets, which may be sold separately. Plan your purchase accordingly to include all necessary components for installation and use.
