off subject but close;I ment to add the reason I came up with this Idea was because i was watching a show where a guy put pipes under his grow soil area and built a greenhouse on top and heated it with a wood burning water boiler in northern Alaska with snow on the ground and -50c weather outside and inside a 20c, he was able to grow all kinds of vegetables and even fruit baring lime trees and lemon trees, So I figured if a man can do that off grid in the middle of nowhere, I should be able to do something similar and less costly here at home in my backyard.
homemade water heater
i tried to build pool water heater with a 40gallon drum sideways on 4 legs and a old wood stove fire door on front(wanted the air vents), then i ran copper pipe around barrel to heat water. It would create it's own flow of water but the problem i had was the fire barrel would get way to hot and create a vapour lock in the copper pipe thus disrupt the flow. I tried to moderate the heat in barrel but i could never keep it from getting vapour lock eventualy. there are a million youtube video on this now but i could never get it to work where i trusted it not to vapour lock.
My orginal heater was a solar heater i build on roof of garage. Build a box with plexiglass top and rolled black plastic piping inside, it worked the best and was about 80-90f but never ran it in winter, think it would freeze up.
So your back to hunting a old boiler down, natural gas would be the best. you need old house you can ripe out the stuff, who knows maybe you can bury the old radiators in the dirt as your pipes.
