If you are looking for shop heat, consider a Modine Hot Dawg or a Reznor UDAP heater. I think you can buy the Hot Dawg heater at Mills Fleet Farm for about $400. Also the venting will add to the cost too. In the end instead of just a convection wall heater you get a heater hanging from the ceiling, out of the way, with a fan to help circulate the air. It depends on how big of shop you are heating as to the size of heater, of course! Greg

I'm only going to be heating a largeish single car size garage. I'm not sure right off hand what the measurements are. It is well insulated, but being a garage, there are areas around the door etc., that show some light. I will check into the Hot Dawg and see what size they recommend. Sounds like I will need a good heater. The wife said snowing, blowing and 50mph gusts. Not nice...

1-1/2 car garage should heat very well with a 30,000 BTU Hot Dawg. That is the smallest they make. Weather strip the door well to cut down on the drafts. I assume the overhead door in insulated?
I have a 50,000 BTU residential furnace in my garage. It is a model that can be laid sideways so I hung it near the ceiling, added a air filter and a bit of duct to it. My garage is 24 x 38 feet, and it heats it well, t-shirt weather all year 'round. Plus I also have AC connected to it all to, so in those hot humid, misquito filled evenings I can close the door to stay bite and sweat free! Greg
Sounds like the 30,000 BTU unit is the one for me. The garage is quite well insulated, but as you say I will have to weatherstrip the door a bit better. With the two electric heaters in there I can maintain decent heat, but it takes quite a while to heat it up. I never thought about air conditioning. That's another possibility. Maybe even just a window type unit.

I just picked up a 35,000 btu "Reddy Heater". My shop is 20x20 and the walls are insulated but it has no celing (want storage) and the trusses are not insulated yet. It was 8 degrees in Iowa the other morning and I fired it up - in twenty minutes, I could take my coat off.

I had a window unit before I ripped it all out and went this way. It helps that I do HVAC work for a living! The condensing unit cost me nothing, it is actually parts from two differant units that were heading for the trash. The furnace was a scratch and dent from a distributor we deal with. Greg
