This heater delivers 40,000 BTU of heat output, making it suitable for well-ventilated construction sites, barns, warehouses, and workshops. It runs on propane and uses a standard 120V connection for the fan and ignition, so it can plug into a power source while the propane tank supplies the fuel. The included 20-foot hose and regulator get you hooked up quickly, and the ETL certification helps you buy with confidence.

Product Details
How a Forced Air Propane Heater Works
A high-output fan pushes air over the combustion chamber, sending a stream of hot air into the work area. Because the heater uses propane, it can deliver far more BTU than a typical electric space heater.
Safety and Placement
Always operate in a well-ventilated space and keep the heater level. Maintain clearance from combustible materials and never leave it running unattended. Check the fuel line and regulator for damage before every use.
What's Included
This kit includes the heater, a 20-foot propane hose, and a regulator. You supply the propane tank and a 120V outlet.

Good heater
Heats my garage quickly. It's loud, but it's a propane heater. Need to open a window for ventilation.

Great for the workshop
I've used this in my workshop all winter. It warms a 30x40 space in about 15 minutes. The fan is strong and moves the heat well. The propane hookup is easy. With a 20lb tank, I get maybe 10 hours on low. It's important to keep the area ventilated because it burns oxygen. But as long as you crack a window, it's fine. Solid machine.

Good but smelly at first
It works well, but there's a strong burning smell when you first use it. It goes away after a few minutes. Make sure to run it outside initially.
