I have it set to 65 right now. It is currently 50 outside. Its only kicking on every 30 min or so for about 10 min then shuts offMy calculations say it is close to twice of what he needs. It is only 600 sqft.
Plus you don't have your over head door insulated.I have it set to 65 right now. It is currently 50 outside. Its only kicking on every 30 min or so for about 10 min then shuts off
That garage space should be very easy to heat with only two exposed walls and the house above. I am certain a 5KW heater would have heated it. You know already, but you need to do something with the door, personally, I would replace it over trying to insulate it.
I had to heat my 1600sf studio with electric -- Simple Qmark two output electric .. think it was 3500 - 4500 ... Watts. Anyway -- under 15k BTU -- no problem in PA in cold of winter.
He has twice the fire power and less than 1/2 the space.
In most situations it is more comfortable to have a smaller heater running in a cold space vs a really big one -- on and off for short times. When the heater is "on" blowing warm air in your direction you feel warm -- the second it shuts off -- you are cold

I can start another thread for this...but this little heater does a great job at heating up my garage. Even with an uninsulated door it is holding the temp at 65 pretty good.

Suggest you may want to read your power meter every few days to make sure the bill doesn't get out of hand.
I'd likely be shooting for a much lower set temperature. 50 maybe.

I only have it set that high right now because I just poured a concrete table top and I want it to cure at a good temp.Suggest you may want to read your power meter every few days to make sure the bill doesn't get out of hand.

Every hour that heater runs is another dollar on your electric bill!I can start another thread for this...but this little heater does a great job at heating up my garage. Even with an uninsulated door it is holding the temp at 65 pretty good.

I don't think it is really oversized at all. I think its rated for up to 750sq ft and I'm at 600. I've been using it at the low setting.
80k BTU is definitely overkill for a 20x30 with 50' of shared wall with a conditioned space. I have a detached 24x30 with R13 walls and R22 ceiling and use a 45k BTU. It's adequate. If I had to do it again I'd consider a 60k or 75k BTU unit. I like it warm at 72* minimum and I appreciate a quick temp rise when opening the door.
45k will go as warm as I want I keep it at 60* and turn up to 72* when I'm working, well under an hour to increase the temp and doesn't cycle often. When I got this place it had a 115k BTU furnace in the garage and while it heated up super fast from the 40*-50* I kept it at then, it was less comfortable as it cycled often and I'd feel the temp swing from cold to hot and back. Oversized can work if you open doors a lot, but too oversized is less comfortable and the temp in the space will have large swings and of course lead to shorter heat exchanger lifespan from condensation.
