Standard 300 Liter Solar Water Heater
Passive Solar Water Heater Pressurized system with attached water tank Weather Resistant Heat Pipe Technology For use in locations where freezing temperatures are uncommon Backup electric water heating element included Includes passive solar controller for timing electric backup water heating Description of Passive Solar Water Heater ApplicationPassive solar water heaters use vacuum tubes with heat pipes and an attached water tank for direct heating of potable water. Sunlight enters the tubes, converting into heat at ~94% efficiency, and is then carried up through the heat pipe to the manifold which heats the water inside of the attached water tank. Water is supplied at the inlet from city/well water, heated and then fed directly into the hot water plumbing of the building.This unit includes an electric backup water heating element and a TK-7Y controller. The passive solar water heater controller is used for timing of the backup water heating and display of the tank temperature. Sett
