Diy Solar Water Heater For Greenhouse. Flat plate solar water heaters use the greenhouse effect to trap solar energy and thus heat up some form of metal plate, which in turn heats up water in pipes thermally attached to that plate. In any compost heap (as in the hotbed described above) heat is generated by the decomposing materials.
The soil is heavy clay, so a few 90cm (3ft) deep holes were dug beforehand and filled with water to check for drainage. 2 thin metal sheets, covering the entire collector box they will be put in, are glued together. The general idea is to stack 55 gallon barrels filled with water inside the greenhouse.
