The maximum thermal efficiency of the solar water heater occurred at the irradiation intensity of 947-1086 W/m 2, the water flow rate range of 2-3 L/min, and its value was 0.67.
The Evacuated tube collector consists of a number of rows of parallel transparent glass tubes connected to a header pipe and which are used in place of the blackened heat absorbing plate

Evacuated tubes absorbs the solar thermal energy, then transfer the heat through the heat pipe to the pressure tank and raises the temperature of the water inside the tank. Evacuated tubes doesn't touch the water, the system can withstand the pressure. In the discharge from the solar water heater without pressure, withstands pressure.

If all the tubes are in place, tighten the geyser tank to the frame. This is a low-pressure solar geyser; installing it as high as possible will result in a higher static water pressure. Be careful not to break the small glass nipple at the mirror end of the glass tube. Keep the nipple of the glass tube on your foot while holding it. 7.
The tubes are made of borosilicate glass, which is strong and has a high transmittance for solar irradiation. In order to reduce the convection heat lost, the glass tubes are evacuated to vacuum pressure or less than 10-3 Pa. Stable vacuum seals are ensured by using a patented technique employing high heat and pressure.

This Warranty is applicable to the original dealer only in accordance with the Warranty terms and conditions specified below. This Warranty is not transferable.
The water volume capacity of the header pipe is less than 1.5 litres for the 30 tube collector, thus allowing fast heating during even overcast conditions. This is important for areas with lower solar irradiation or overcast conditions, as the heat from the manifold can be quickly harnessed, then held in the storage tank.
