Another method Two points of method: (1) Two waters, separated, zero pressure and house pressure, and (2) Use principle of heat-exchange to take heat from zero pressure to house pressure by running copper metal tubing with house pressure, inside the zero pressure water. The copper metal does a very good job of transferring the heat, and many times better than plastic or rubber. Mixing sand and water in the zero pressure water is probably better. Thin aluminum may contain the zero pressure water.

what would you do in the winter when the suns not out

[signify12]

uv rays and infer red rays still get through and that is the main form of heat and energy. thats why you still get sun burned when the clouds are out. you just need a system with a lower heat capacity than the surrounding air.
