Working principle of high pressure solar heater: utilizes the alternative absorption coating on the inner surface of the vacuum tube, from the high - temperature environment super - conduction tubes lead the heat to the water tank, and produces hot water. Easy to use, also convenient to install. Can be put in the courtyard, on the roof or balcony. Inlet water hole connects to the tap water, and the outlet hole connects to the tap water, and the outlet hole produces pressure hot water directly.
Working principle of low pressure solar heater: adopts the alternative absorption coating to absorb the solar energy, through the cold hot water convection, heat the water in the vacuum tube directly, changes the solar. High-capacity gravity-fed solar water heater uses the power of the sun to heat water for homes, summer cabins and fishing camps. You can save money on hot water heating costs and help the environment at the same time.

Water tank capacity: 252L. Vacuum tube specifications: Ø58 x 1,800mm. Vacuum tube quantity: 26pcs. Sunlight collection area: 3.4sqm. Excellent electric heater——Avoids the electric leakage and rust and get rid of the dirty. Owning the clean, hot water every minute. Safe and convenient. Saving electricity: Solar geysers can save a large amount in electricity bills over time. Each solar geyser can serve two or more bathrooms, further adding to energy savings. Hard water: Since glass is inert, scaling (by hard water) will not occur. The glass tubes can be manually cleaned if required. Proven, reliable aerospace technology offers long term performance and extremely low maintenance.A neat and clean insulated make-up tank can be mounted on top for equalizing water pressure/flow to heater.
