My father installed a solar system and radiant-heat floor in his barn
A couple of years ago, my folks retired. Pops ripped out the bottom of the barn on the old family farm, set up a woodshop, and got to work. Check out his stuff here. Nice, eh?
I’m pleased to say that Pops’s pots are now solar heated. With no urging from yours truly, he installed a radiant heat floor powered by a solar system on the south side of the barn. When the the thermostat senses a >10 ° heat differential between the outside air and the floor, it circulates ethylene glycol, in a closed loop system, through the solar collector and then through tubes embedded in the concrete floor. Now, the barn is a big space, and the roof is only insulated when there is hay in the mow above, but Pops reports that it works pretty well.
