Modine Hot Dawg Size?

[Stevelaz]

Hello everyone. Im in Chicago and currently looking at the modine hot dawg heaters and am torn between which size, 45,000 btu or 60,000 btu. I have a basic 2 1/4 garage that is i believe 22x20. I am replacing the window and the overhead garage door with an 18 ft insulated door. I will be insulating and dry walling the walls. I basically use the garage for working on my cars and and occasional bodywork. I want a furnace that will heat the garage fairly quickly after opening the door and pulling car in. Any thoughts and remarks what you have would be great. Thanks.

I recently built a 1,000 sf garage with 12' ceilings and I installed 75,000 btu Hot Dawg. It seems to work just fine. I am in Rhode Island and we just had arctic cold winter. Garage heated with no problems. 2x6 insulated walls.

Sounds like you might be a tad overkill with the 60k unit at 440 sf of space. Modine web site has sizing calculators.

Good luck. I think either one will be fine for your application.

I'm in the same boat, I have the older 40,000 and it works plenty good, I have a ceiling fan to blow the hot air down from the top down to the floor. It will surely keep the snow melting all over your face in the winter

I have a 24X36 garage with an 8 foot ceiling, 2X6 construction. I have R-19 in the walls and R-30 in the ceiling. I have a 60,000 BTU Hot Dawg and it works great. It is probably more than I really need, but I turn the heat down to 50 degrees when I am not working out there and when I turn it up to 70 degrees it gets the temperature up there pretty quick. I am completely satisfied with it.
