General Outdoor Furnace Discussion / Re: Building water to air unit heater

How large a radiator do you think I'll need? Should I have the radiator and fan inclosed so that all the air goes threw the radiator?

I have a 40x60 shop with 1/2" insulation in SE Tennessee. I would like to build a water to air heater with thermostat. Any ideas? I've been told AC condensers will work. Any ideas on how to make this work would be great.

I never thought that painting the water jacket would stop the condensation. I wanted to protect the steel from the condensation. I didn't know if the heat would have some adverse affect on the painted steel or maybe a flammable chemical off gassing.
I just thought it strange that the manufactures wouldn't paint it for no reason.

I was going to paint it yesterday but then thought, maybe they don't paint it for a reason.
Do any of the OWB manufactures paint the bare steel. I would think you would have condensation.

Has anyone found more details on heating a driveway? I've searched it a few different ways on here but it tunrs up every post where someone mentions their driveway. I was thinking of doing a closed system with its own pump, using antifreeze and a water to water heat exchanger. I wouldn't want to heat it all the time, just when it snows. Not sure how far apart the plumbing would be effective in the blacktop, or how deep it should be
Several years back I was going to put pex tubing in my concrete driveway "I was building a new home". I talked to a friend that put it in and was told that unless you have a lot of slope on you drive not to bother installing it. What happens is the snow melts to water and flows to the end of the concrete and then freezes creating a ice dam at the end of the concrete. If you have lots of slope the water will run away before freezing. I did put it in my basement, garage and porch. I own a concrete poured wall and flat work company and have done many jobs with in floor pex. Biggest being over 100,000 sq.ft. Everything we did outside was spaced one foot and ran approx. 200' per run.
Interior infloor tube would run six inches apart along exterior walls then every foot.
Never seen it in asphalt.

I have a older Taylor wood furnace that had a water leak. I took all the insulation off, cleaned it up, welded the area that had leaked. Put high temp lab metal over the weld area. Should I paint the water jacketl to prevent rust? I know that the stove can sweat. Should I use a high temp paint?
