How are you heating your shops

Theastronaut, how big of a water heater are you using for your setup? The more I look into a hydronic heating setup's, the more I think I'll look at building one.

It's a tankless heater. It has a copper coil inside that the water flows through instead of having a tank that the water flows through. The coil sits in an inner tank that is heated by a single central element in the middle of the coil.

Pritch, here'a a shot of the boiler we're building for our house. Will have two stainless water heater elements (I forget the wattage, maybe 5500?), a temperature/pressure based pop-off valve, a temperature probe for the thermostat, a temperature/pressure gauge, a drain, and the in/out pipes.

Very cool! I have been thinking of looking into a used-oil boiler of some kind. I know I should be able to get hotter than what I get. I probably could with a natural gas unit, but I don't want the shop to be hooked up to the gas line, or else it would be 80 degrees inside it all winter and I'd be broke

I want to get like a 200 gal propane tank and fill it once per year. Another problem I have is it seems like if the fans on the unit heaters ran slower, much slower, it would be more efficient. Oh well. I like tinkering with it. I have an idea for more solar, too. Free heat is the best kind

Just an el cheapo 200.00 mobile home furnace. When it gets warm I just pull it out of the window and stick it in the barn..
