Here you go... solartec.iinet.net.au/ solare/ secondary/ solarhotwater.htm These are plans for a smaller version. I have seen books in the library that have plans but as of right now I cannot remember the names. I will try to look and then let you know. This is a nice how to for a small scale passive heater. I have seen larger (like 4'x8') home made panels used in ND to heat small buildings. It wouldn't get it to 80, but it surely takes the chill out. Note: these wer closed loop systems that used antifreeze, radiators, and a thermostatically driven 12v solar powered citculating pumps. |
