How Thermosiphon Water Heaters Work

Your FreeFlow Solar Water Heating system is known as a “passive” solar water heater because it does not require mechanical pumps, controllers, or any moving parts to make hot water. Thermosiphon solar systems work on the principle of natural convection, or the fact that heated liquids rise.

The FreeFlow storage tank can be equipped with an optional electrical heating element that can provide hot water during periods of inclement weather or high use. In two-tank systems, the supplemental electric or gas water heater will provide backup water heating if necessary.
