high quality and trust worth Solar Water Heater - XSPT-180L-18

solar hot water energy

Working Principle:
1, Vacuum tube absorb solar energy, heating the water inside of vacuum tube
2, According to density difference, the cold water through down into vacuum tube, and hot water flow up into solar tank
3, After circulation again and again, all of the cold water will be heated to hot water and storaged in solar tank.

Features:
1, The system is nonpressurized, drop water must rely on height difference, so the solar heater must to install higher than users
2, Exhaust vent or Exhaust pipe is most important for protection the solar heater system

Material:

Inner tank: stainless steel SUS304/2B, 0.41mm

Outer tank: galvanized/ co lour steel, 0.31mm

Frame: galvanized steel/stainless steel SUS304/aluminum alloy, 1.5mm

Insulation: polyurethane frothing, 50mm

Vacuum tube: AL/N coating, 47*1500/58*1800mm

Accessories: MG rod, electrical heating, assistant tank

Logo: OEM, co lour printing /sticker

Accessories: Optional
A), Assistant tank:
Assistant tank have a float valve, when you put water into solar tank at first time, if the solar tank is full, the assistant tank will controll to stop into water.
When the water in tank have been used or evaporated, the float valve will drop down, and cold water will into assistant tank again
B), Magnesium rod: Soften water, protection solar tank
C), Electric heater: Assistant heating by electricity when the water could not satisfy your demand.
D), Controller:
Controller can showed water level and water temperature, also can setting time for put into water and assistant heating

Usefull life: 5 years

Working Principle

Solar vacuum tube was evacuated into the tank; the coating inside of tube can absorb more than 92% heat energy from sunshine. The cold water in water tank flows into the tube and become hot, because of different density between cold and hot water, there will be a natural circulation in the tube, and hot water will float back to tank. 50 mm thickness heat insulation layer by polyurethane between inner tank and outer tank can keep the temperature of hot water for about 2 days without any sunshine, consumer can enjoy comfortable bathe anytime.
