Complete Solar Water Heater
21-Tube Solar water heater system-Freeze Proof. Large enough capacity for a typical 3 bedroom house in mid-latitudes. No pumps or controls required, can work off grid. Optional controller and electric heater for on grid constant temperature hot water
evacuated tubular collector design with sealed heat pipes. 158 liter stainless steel tank, aluminum stand, pressure relief vent, water inlet and outlet fittings, tank cover, foot cushions, end caps and reflectors are all included. This complete, independent hot water system for a house is ready to use when water is supplied. Vacuum tubes can never freeze, since they contain no water. Optional auxiliary electric heater and controller can keep water temperature constant. Insulated tank alone is freeze proof for 10 months of the year in Canada, but with controller and electric heater the system functions as a year around hot water supply even through Canadian winters.
