1, from the heat collecting part to:
Vacuum glass tube solar water heater: heat collecting heat absorption efficiency is the highest part, the utility model has the advantages of no need, in the heat collecting part in increasing the insulation layer, and the vacuum glass tube in the now anti high temperature, anti crack and heat insulation performance, are first-class, also be the vast majority of the production of solar water heater used by the manufacturers. Its disadvantage is that the larger scale, easily assembled pipe.
Metal plate solar water heater: sheet metal on the heat transfer performance is excellent, covered with heat absorbing coating, the heat transfer metal, will absorb the heat in the water tank. The point is the beautiful appearance, easy installation, can be made into a flat, and not easy to damage. Disadvantage: to spend big price, the high cost of indirect heat preservation, is to increase the burden on consumers.
2, from the structure to the classification:
Ordinary type solar water heater: is the vacuum glass tube is directly inserted into the tank, the heating water cycle, so that the water temperature in the water tank rises, this is the manufacturer. Is also a popular to the water heater the conventional now. The general class of water heater only the top layer can be used, unless special iron top users and your downstairs, and the roof area is limited.
Split type water heater: split water heater is not the top in order to solve the user can also use solar water heater and the birth of the. Split cycle has 2 kinds, one is relying on the natural circulation of water, the water heater heat exchange efficiency is very low, far can not meet the water requirements; another is by pump circulation heat exchange, which is in order to solve the problem of low efficiency of natural circulation, a pump is used to circulate, can obviously improve the water heat exchanger.
3, from the tank pressure points:
Pressure bearing type solar water heater: at present, no matter what kind of split water heater, has a fatal defect, must use the pressure bearing type water tank, which is the basic ideas of all split type water heater, which direct test of heat set your part of the sealing performance; and the high cost of manufacturing pressure tank, also the problems of the safety of the general requirements of 7 atmospheric pressure, but the effect is not very ideal cycle. Although the convenience of water circulation problems and the use of water.
Non pressure solar water heater: ordinary solar water heater is installed on the roof are belonging to the non pressure bearing type water heater, the water tank has a tube is communicated with the atmosphere, the roof and the height difference of home, pressure water use. The safety, cost, service life is much more effective than the bearing type.
Vacuum glass tube solar water heater: heat collecting heat absorption efficiency is the highest part, the utility model has the advantages of no need, in the heat collecting part in increasing the insulation layer, and the vacuum glass tube in the now anti high temperature, anti crack and heat insulation performance, are first-class, also be the vast majority of the production of solar water heater used by the manufacturers.
