Passive 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 solar controller. The passive solar water heater controller is used for timing of the backup water heating and display of the tank temperature. Settings on the controller help prevent heating water when hot water will not be needed, such as during 4 in the morning. This gives the user the ability to only use electrical backup heating when it may be needed, thus giving the sun a chance to replenish heat.
1) Pressurized tank, working pressure 6 bar, Max resistance 12 bar.
2) Reliable and efficient twin-glass solar tubes
3) Copper heat pipes for rapid heat transfer, No water through the tube, So it can good working in winter without freeze.
4) Easy plug-in installation.
5) Free maintenance.
6) Stable solar conversion during the day.
7) Ideal for home applications.
