Solar Home Heating
Heat your house with solar thermal (hot water) collectors. You can buy them, I made my own. There are 3 in this arrangement. 1 square foot of collector heats 1 1/2 US gallons of water 40 degrees farenheit in Pennsylvania, USA in winter. The more collectors you put up the more water volume you can heat. Most people use one of these collectors for domestic hot water, showers, etc. I used mine to heat my house. Of course insulate well first, then see if you can use this. You’ll need to add radiant floor heat system to get heat out of tank. It all cost about 00 in materials, 3 x 4′ x 10′ collectors, tank, fittings, pipe, differential thermostat, pump, insulation, collector box, etc. This system would be great for heating greenhouses thru the winter, almost free, once the up-front costs are met. tonyfixit.
