Garage Heater Question
Do the combination A/C and heater units work well in Maryland type weather?
In the summer I would like to reduce the humidity and in the winter it would be really helpful to be able to work out in the garage in temps over 60 degrees so I can work a little with paint in doing the motor, undercarriage etc...
I was thinking about a 10,000 btu unit might suffice.
Thanks,
Bill

It's 19 degrees in Chicago and I have my heater on and its 70 degrees in the garage. Washed the whole fleet today. I have a Reznor 35,000 BTU and it took an hour to get a two car garage up to 70 degrees.
I am thinking about putting in a AC window unit into the wall. I agree with you on the humidity.

Hello,
Depends how big your garage is and if it's insulated and how quickly you want things to warm up and how warm do you want it.
I have 1000 square foot garage an I installed a 90,000 BTU Dayton ceiling mounted furnace and I can get 75 degrees in 10 minutes on the coldest day here in Green Bay, however the air is only 75 degrees at that point, the cars, benches and walls take more time to reach 75. In my opinion a 60,000 BTU would have been enough but I would be waiting 1/2 hour to get the garage warm.
Some guys like to size their garage furnace as though they were heating a house. For example my house is 1800 square feet and my furnace is 60,000 btu, but the temperature in my house only swings 4 degrees (setback thermostat). In other words, I never have to warm the house from 25 degrees to 70 degrees and if I did the furnace would run all day to get it there.
To make a long story short, bigger is more convenient. And my 90,000 BTU Dayton was only $620 last year, I ran the pipe and the electrical and I already had insulated and plastered/painted the walls and ceiling.
Good Luck,

Here's a simple calculator to determine how many BTU's you would need to heat the garage.

I just built a 24x36 in Alexandria VA with a full 2nd floor upstairs. I have 12' ceilings for the lift I installed. I went with a heat pump unit, 2 ton and it does a wonderful job keeping down the humidity in the summer and warm in the winter.
I don't like anything with a pilot light anywhere near a car because of possible ignition from gasoline vapors. If you intend to do some light painting with any kind of heat source that has a flame in an enclosed area you better up your life insurance policy soon.
My heat pump has an auxuilary heat strip if the temp goes too far down where the HP is no longer efficient , this will keep the pipes from freezing in extreme weather and so far the HP has not required the strip to kick on. I do have it very well insulated with top of the line insulated doors. I put a wall mounted heater in my bathroom just in case, that too is electric.
Good luck,
Jeff
