"This is absolutely the best heater I have ever had in a garage. I have tried electric heaters, kerosene, wood stoves, ventless gas heaters, and this one beats them all.
It was easy to install (assuming you have a gas line handy), and it provides clean heat with virtually no noise. Since the exhaust is powered, it was simple to run the flue through a side wall to avoid punching hole in the roof - no leaks!
By mounting it on the ceiling, I regained the space that had been claimed by the smelly ventless space heater mounted on the wall.
I can warm my 30x30 garage from 30 degrees to tee shirt temperature in about 15 minutes. And since it is vented to the outside, my garage is constantly supplied with fresh air. No more choking fumes, and recirculating welding smoke.
I wish I had done this a long time ago. Overall - a robust product at a fair price."
