Hot Dawg heater sizing

[mikeyr]

I purchased 3 years ago a Hot Dawg 45 which is for 400-600sq. ft. I am now building a new garage that will be 840sq. ft.

What are the problems I am going to run into if I stay with this size heater or should I upgrade to the next size up ?

I am in S. Calif. so I am not talking freezing here, if we get down to low 30's at night its only a few weeks of the years but I do like to keep my garage at around 50 when not working in there. It will be well insulated when finished.

I am thinking I will try it this winter anyway just since I already own the thing and I assume it will just run longer but work just fine but thought I would ask first.

It will be plenty.

You might find this heat load calculator helpful.

With good insulation and tight construction, you should be fine with the HD45.

Thanks Stitch, that heat calculator says I will be just fine.

Final inspection is "scheduled" for Tuesday so I will find out soon.
