Rated 3.9 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by Great heater that will heat a 2-3 car garage. I purchased this heater a few years ago for my two car garage. I have been using it more so lately than ever. At the time of initial installation the garage was not finished having only insulated walls, no ceiling and no insulated door. Since then I put r19 on the ceiling so that in case something gets stored in the loft it will not compress it. I also cut out pieces of foam and glued them with foam glue to the door. Having just the ceiling above was a major improvement by itself. Previously you would have to max the heater for a couple hours since heat was going up in the rafters and out the vents. A temporary way to remedy that was to set a box fan on the rafters and point it downwards. It does help a lot. Soon as the garage had a ceiling/insulated I could leave the heater 1/2 way turned up on the dial for 30 minutes and go from 35 degrees to 60+ degrees. Once warm in there a lot of times after 1 hour or two I have to put it at a lower setting. Be careful when installing and don't just go piping in natural gas right way to the open port. The heater came setup as propane by default so I had to remove the pipe plug from the the natural gas side and plug the propane side. The hardest thing about the install was running the gas line out to the garage. I Tee'd into the dryer and ran it off that which is no biggie. I have not had any ill effects with the heater from doing that. The nice thing about the heater from installation standpoint is I did not have to run electric to it. It uses a grill ignitor for spark to ignite the pilot light. The heater will adjust from 15,000 to 30,000 btu automatically and regulate from there by shutting off if reaching a desired temp leaving the pilot light running. Gets too cold it will kick back on how it should. I installed a carbon monoxide detector and smoke alarm just in case in the garage. I know many people don't like a Carbon Monoxide in the garage but it has worked fine for me. Let the heater run good and hot for hours because it will stink on the initial first time use burning off that new casting smell. The garage it is installed in is 20x20 with a 10ft height ceiling. I installed a small shelf above the heater right near the ceiling with a small squirrel cage type fan. Above that I have an outlet that is shared on one bank of lights in the garage near my workbench. I keep the fan on low all the time so when I go out there to work and turn on the heater my fan is circulating also. I have it blowing towards the workbench and warms up all the tools faster I have hanging on the wall. All in all I'm satisfied with the heater. Would I have liked a vented heater, sure. Would I have like a vented price that goes with, no. The cost associated with piping it, also punching a hole in my roof no thanks. Yes it would be safer and if I lived out there I would go vented. You'll hear they are unsafe and shouldn't be sold from others out there. Perhaps they never cleaned theirs? Blocked Ports? For the heck of it I brought home a gx-2009 gas detection meter that I use for work to do a constant monitoring of the atmosphere. If there was a problem it would go off. I had the heater on all day and purposely cranked up the heat to try to bring the levels higher. Putting the meter near the ceiling, eye level and then finally resting on the floor where 'fumes' should be if there are any. The meter did not go off once. This meter is bump tested daily so it is a good meter. Now, would I say a ventless is better than vented, probably not. But for ease of installation and if you put a carbon monoxide detector and smoke alarm out there I don't see a problem. There is a low oxygen sensor built into the heater so it will shut off. I figure its an extra safety measure having the carbon monoxide detector in the garage, which they do not recommend because your car can falsely set it off if you don't pull the car out soon. I've only had it get set off once on accident remote starting the car while the garage was closed. Of course it will go off. As for people who complain about moisture from this type of heater it will put off moisture but not too bad. Its a byproduct of burnt gas. If you leave it run for a long time the floors may sweat. The only time this concerned me is when I mudded the walls and painted the inside of the garage. I didn't want high moisture in there so everything could dry so real simple I brought up the dehumidifier from the basement ran that. Yes, it now costs extra money to run another device but for the time I plan on painting it is still possible to do so with this heater. Long story short if you want an easy install and not have to worry about local codes on the external of your house install this and works fine. This would be perfect for anyone that has a town where you cannot run a stack outside because of the association. My father in law has been running this style heater for years on his converted porch to sun room and works perfect. Opens it up to the house and turns on the aux heater. Good Luck to what you choose. This works fine for me. December 11, 2012
Rated 5.0 out of 5.0 by Works Great, Exactly as expected!! Since it's been over a month since purchase (thanks to gas companies being busy) I can finally rate this heater. Works great, more that what I expected; as this is my third vent-less heater. Heat output is great, have it installed in a 2-1/2 car garage (un-insulated and non-sheet rocked) kept it on high, managed to get to 62 degrees. Some work for me to do to insulate, but more than impressed with how it managed to get the temp up!!! I installed the blower, and as others state, I have work to do to get it to work an auto.

Rated 4.0 out of 5.0 by This product meets my requirements This product was easy to install and meets my requirments very well. I will use it if the electric or my house heater breaks down. January 2, 2014
Rated 3.0 out of 5.0 by This product performs OK heating the garage but has limited control if you just want to keep the garage above freezing. I was very disappointed in the structural integrity of the mounting hardware. I accidentally bent the mounting hardware while pushing down on the button to light the unit. February 11, 2014
Rated 1.0 out of 5.0 by Complete junk ! DO NOT BUY THIS HEATER !!! Mine quit after one season. The only thing worse than the quality of this heater is Pro Com's customer service. February 28, 2013
