    One guy I saw had a walipini and he captured the rainwater from the roof. The rainwater was stored in 55 gal black drums. With his setup the sun and the greenhouse warmed the barrels by day and the barrels (which were now heat banks) warmed the greenhouse by night.

    BigKid’s on to something there though. You could do allot with a simple solar heater, especially if combined with a tank to act as a heat bank. With pex pipes you could heat the soil itself, any raised beds and the greenhouse. You could circulate the water with small 12v solar pumps. If you chose too you could do a closed loop system using a “green” antifreeze.
