Can this be set to keep a two car garage above freezing...say 35 degrees in a climate where the temperature rarely falls below 20 degrees?

If you had enough insulation you could heat it with a light bulb. But I am going to say I doubt it would work. It works well to augment the heat in a cold room with bad windows.

YES..it has a thermostat, it can be set so low that it will only come on at freezing if desired.

I've had my garage (400sqft) down to 70 degrees. The outside temp today was 92 (heat index of 101). I would check the insulation above the bedroom and other possible factors, maybe even a bad unit.

I think it's going to depend on how cold your winter gets. I don't know if it has any guidelines about temperature (it's at my grandkids' house) - but I would expect that the material might become brittle below 40 degrees. I doubt it would be wise to set it up below 50 degrees. Please note that this is conjecture only. I know that my daughter has set it up in the garage several times during the "colder" months in Virginia.

Probably so, I have two of them in my motorhome, which is approx. 300sq.ft and they kept it at 72 degrees inside, while outside got down to 28 degrees! It depends on sq.ft. of the garage, and how well it is insulated, you might need two.

The lock would do it but if the freezer is exposed to very low outside temps, the adhesive on the attachment may fail. It's not supposed to be under 60 degree F.

I installed in the winter and never had an issue. VA doesn't get too cold for long but it does get in the 20's and 30's. As I said, never had an issue...attached unheated garage.

I would say, yes. I know mine has been effective and I store mine in a garage where the temps reach into the high 90's in the summer.

We live in Illinois, it works fine here. Our winter may not have been as bad as yours, but it was COLD. Don't know if it makes a difference or not but our car is in attached garage overnight.

Not sure if a car battery can be added, but at any rate it will shut off when temps. go below 85 degrees

It should do the job. The thermostat is not really precise and starts out at about 60 degrees. I use it to take the chill out of my 3 stall garage and it works (central CA region) .

I'm not sure. My unit is kept in my kegerator, which stays around 35 degrees F. I'm not sure why you would have humidity issues in a car in below freezing temps.

Yes on the switch. The size of the garage is the factor you have to calculate. My shop is 16x24 insulated and from 40 degrees to 60 takes about 20 min when the outside temp is -25 degrees.

Yes. We are amazed how much it keeps the heat out. Don't get me wrong, in Texas hot summers it still can get hot in the garage.(in 100 degrees). But it definitely works.

My shop is in my unseated garage. It doesn't get below 40* The humidity is lower when it's cold so the unit runs a lot less than in the spring and summer, but it functions fine. Of course, if you mean below freezing when you say low temperatures, it wouldn't work, it would ice up.

I got one last year, my garage is unheated too, dont use heavy load when its cold and it work fine

This mat can maintain 10-20 degrees F above ambient temperature. I don't think it will be able to maintain something from freezing when the ambient temperature is below zero (temperature differential is more than 30 degrees F). You will need something else to help it out such as extra insulation or an additional heat source.
