Very good heater

I've been using this heater with excellent results. I originally bought a smaller model, but ended up needing to purchase the fan and adapter hose separately—both of which are already included with this one at a much better value. The fan even comes with an adapter so it can run on batteries or be plugged in. Overall, this is a great heater at a fair price.

Heat when you need it most!

Texas winters don't normally require a secondary heat source -- unless there's ice and incredibly cold temps. 2021 just about killed me. Surviving 2026 snowmaggedon just fine with this heater!
