Solar Water Heater Tank Design

A solar water heater can be made from a few pieces of pvc pipe.

Solar water heater tank design.

Running by gravity no need for circulating water pumps build design plans diy passive solar water heaters are more reliable and relatively inexpensive due to the lack of electronic control equipment thermosiphon the water is heated down the cold water drops the hot water rises so the water tank is above the collector active solar heat convection. If additional heat is needed it is provided by electricity or fossil fuel energy by the conventional water heating system. A metal tub or stock tank can be used to make a solar hot water heater. Add a solar water heater to your roof.
