I didn't know exactly where to post this....

Are Propane radiant heaters safe to use in a small garage setting?

NO.... Most areas forbid any type of "Open Flame" heater to be used in a garage. There is the possibiliy of igniting gas fumes.

Now if you are just asking about the posibility of carbon moxide, these usually have some sort of catalitic converter built into their burners that change it to carbon dioxide and water.

As long as there is some fresh air, not to bad. Now this is just my opinion.

WoW, this garage is used for storage only. There are no cars parked inside. But no fresh air....

Is the answer still NO?

Tree, I will leave the flamability of items in this Storage space as I am not there to see. Even a can of gas for the lawn mower will be a bad idea.

You will still need fresh air for combustion. Remember what I said, the by products of combution is either CO or CO2 and water. This water will make things damp and possible mildew or mold. It can and will weaken glue and damage wood. To check for this moisture, hold a glass of ice water over the heater. You should see the moisture condensate on the outside of the glass as soon as it gets in the stream of flue gases.

If you really need to keep this space warm, I recomend a through the wall heater. These use outside air for combustion and vent fumes to the outside. Only the heat fills the space.

Now if you are asking if OK to use for an hour or so, I would say OK as long as you have some fresh air so as not to deprive you of oxygen. Be advised that I have friends that will get headaches from these heaters even if everything else is safe.

Okee dokee. You've answered my question. I think we'll change to an electrical heater. Sounds safer to me.

Thank you.

At least you want be changing tanks every 6-8 hours.

By the way, and I should of asked sooner, why do you need to heat this space?

Well, I'm totally into gardening and am trying all sorts of tropical things. I'll be doing a lot of transplanting of seedlings here, and it's nice to be comfy. When the weather is nicer, I can do this outside, but for now, I LOVE this little garage.

My spouse has lots of tools stored here, as well, AND he tells me that he's purchased a new electric garage heater today! Yay!

It's just nice to have the option to turn up the heat while working in this space.

Thanks WoW!

I am happy with my answer.

The moisture from the propane heater would have rusted hubby's tools.
