Our Verdict

This ProTemp heater outputs 125,000 BTU. It covers up to 3,125 square feet. That power level is built for large garages, barns, and warehouses.

You run this heater on propane. That means fuel costs beyond the $195 purchase price. Budget for propane expenses during heavy winter use.

It lacks a thermostat and tip-over protection. These two features are standard on most portable heaters sold today. Use it only in open, ventilated outdoor spaces.

Your cost per square foot is just $0.06. That is exceptional value for the coverage you get. Few propane heaters at this price deliver that ratio.

CSA certification confirms this heater meets tested safety standards. The high-temperature limit shutoff provides automatic protection from overheating. These specs matter in large, uninsulated work spaces.

What We Like

  • Outputs 125,000 BTU and heats up to 3,125 sq ft, covering large garages and warehouse sections.
  • CSA certified, confirming it meets recognized safety standards for propane heating equipment.
  • Continuous electronic ignition starts the heater fast without a match or lighter.
  • Powder-coated steel guards resist corrosion and hold up in tough outdoor workshop environments.
  • Adjustable heat angle lets you direct 12,000 CFM of airflow exactly where your workspace needs it.

What Could Be Better

  • No tip-over protection, a safety feature included on most portable space heaters.
  • No thermostat, so you cannot set a target temperature for automatic heat control.
  • No timer, meaning you must turn the heater on and off manually every single time.
  • Rated for outdoor use only, which limits where you can safely run this heater.
  • Runs on propane fuel, adding ongoing fuel costs that electric heaters completely avoid.

Frequently Asked Questions

Common questions about ProTemp 125,000 BTU LP Propane Heater | For Warehouses, Garages, Barns and Workshops up to 3125 Sq feet (PT-125V-GFA-A)

Can I use this heater inside my home?

No. This heater is rated for outdoor use only. It burns propane, which produces exhaust gases. Use it only in well-ventilated spaces like open garages or large barns with airflow.

Does this heater need electricity to operate?

It burns propane for heat but draws 1.6 amps of electricity to power the blower motor and electronic ignition. You need both a propane tank and a power outlet nearby.

How large of a space can this heater warm?

It heats up to 3,125 square feet. That is large enough for a big commercial garage, a warehouse section, or a full-sized agricultural building.

Does it have a thermostat or automatic temperature control?

No. This heater does not have a thermostat. It does have a high-temperature limit shutoff that cuts the unit if it overheats. You adjust the heat level manually.

Is the propane tank included with this heater?

No. The propane tank is not included. You connect your own LP propane tank separately to power the heater.
