Does anyone use ventless heaters for their garage?

Wow.....Think there’s is proof in this thread that ventless heaters cause brain damage.

I just don't understand the logic. About 3/4 of the folks here who have used them, say they have had moisture problems. Is your workspace properly vented? Guess we will find out. To make sure, you may want to open a door or window a bit. Wait...why are we running the heater? Oh, because it is cold outside. So instead of keeping out the cold air, we are intentionally letting it in now. So we have to run the heater more to stay comfortable. A vent is not all that difficult to run, and if done well, is not all that unattractive. If you really don't want to run a vent, and you want to save some work on the job, and some money......stick an electric heater in there and close the window. I'm not a fan of electric, but I don't work under my car with just the jack supporting it either. There isn't that much difference between running a ventless, and simply venting a hanging heater into the garage.. You wouldn't think of doing that. That would be crazy.
I'm not telling anyone that they are doing wrong if they have an unvented. That is up to you. But for those who are on the fence about it....spend a few more bucks, an do a proper installation of a vented heater. Just my opinion of course. But the op was looking for opinions.

Wow.....Think there’s is proof in this thread that ventless heaters cause brain damage.

And impotence, scurvy and halitosis!

I can assure you that ventless heaters create a LOT of moister! I used mine a lot last year for the first time & the attic roof was completly covered in water & moisture. All of the 4x8 wood panels for the roof were almost dripping wet! not good! I won't do that again. Not good for the wood in my house. My siding on the side of the garage also turned green mold & I had to clean it in the spring. Be very careful how much you use these. I'm going back to only using it on weekends. Good luck! ~

Still using mine (same one) in the same garage 15 years later, still have no problems with moisture or CO.

1. Read the instructions and make sure you have enough ventilation.
2. Have a working CO alarm.
3. Keep track of your humidity and adjust heater use/ventilation as-needed:

Might also benefit from adding insulation too so you don't have a cold roof with moisture-laden warm air rising up to it. Fans/ceiling fans to distribute the heat help too IMHE.

Coming up on 15 years since the OP, glad we have some resolution!

My Electric Heaters don’t have vents.

My Workshop has a 5 KW Electric Heater without a vent. The solar panels provide me with inexpensive electricity.

The San Diego climate doesn’t require much heating.

My overhead dust filter doubles as a fan and moves air around for my 30k BTU Procom LPG heater.

Been running a Ventless Natural gas in CO for 5 years now. Weve got near zero humidity in the winter and i have zero rust issues going on.
i dont run it day and night, just when its very cold to keep my toys warm.
