Product Description
1.The material is different, the non-pressure water tank is used with thin material, and the pressure water tank is used with thick material; 2, the water use is different, the non-pressurized solar water heater by the drop water, called the fall water type water; Pressurized solar water heaters rely on pressure to produce water, called top water outlet. The so-called top water outlet, that is, the inlet of the pressurized heat storage tank and the tap water are connected, maintain the normally open state, the water tank always maintains the same high pressure as the tap water, the solar heat storage tank has a valve, open the hot water valve when using water, under the tap water pressure, the hot water quickly rushed out, this type of water outlet is called the top water outlet; 3, the installation location is different, the non-pressurized water tank can only be on the roof, otherwise it needs a booster pump, the pressurized water tank can be installed in the basement, stairwell, bathroom, attic.
2, pressure solar water heater refers to the water tank closed with pressure operation, isolated from the atmosphere, generally made of enamel can withstand a maximum of 4-8 kilograms of pressure, no water in the collector tube, heating water through heat conduction, the advantages are: low maintenance rate, strong water almost and cold water isometric, Non-pressure is that the solar water heater tank has a vent and the atmosphere, can not be operated under pressure vacuum tube and water, through the specific gravity of hot and cold water circulation to achieve the purpose of heating water, its advantages are: the use of hot water in the same volume, fast heating
3, the pressure type of solar energy is separate, that is, installed on the balcony. Not a pressurized solar bit all-in-one. It's mounted on the roof. The difference between the pressurized solar water heater and the non-pressurized solar water heater is as follows: the pressurized water heater is called the phase change thermal conductivity solar wat
