Solar water heaters are economical, environmentally friendly, safe and reliable. Nowadays, they are very popular hot water acquisition methods. However, there are many types of solar water heaters, which have caused a lot of trouble for consumers to buy. So what solar water heaters are good ? The following decoration home decoration network Xiaobian will bring you a variety of solar water heaters, I hope to help everyone. What solar water heater is good? The types of solar water heaters are divided into: vacuum glass tubes and metal plates. (1) Vacuum glass tube solar water heater: It is the heat collecting part with the highest heat absorption efficiency at present. The advantage is that it does not need to increase the heat insulation layer in the heat collecting part. Now the vacuum glass tube is resistant to high temperature, anti-strike and heat preservation. First-class, adopted by most manufacturers. The disadvantages are relatively large, and it is easy to collect scale in the tube. (2) Metal flat-panel solar water heater: The metal sheet with excellent heat transfer performance is covered with an endothermic coating, and the heat absorbed by the metal is used to transfer the absorbed heat to the water tank. The utility model has the advantages of beautiful appearance, convenient installation, can be made into a flat plate, and is not easily damaged. Disadvantages of insulation have to be costly, costly, and indirectly increase the burden on consumers. The type of solar water heater 2 can be divided into two types: ordinary type and split type. (1) Ordinary solar water heater: The vacuum glass tube is directly inserted into the water tank, and the water temperature in the water tank is raised by using the heated water circulation, which is currently adopted by the manufacturers. It is also the most popular of the popular. This type of water heater can only be used on the top floor, unless the top-level user and your downstairs are particularly iron, and the roof area is limited. (2) Split-type solar water heaters: Solve solar water heaters that are not used by top-level users. There are two types of split-type circulation , one is natural circulation by water, the heat exchange efficiency is low, and it is far from meeting the water requirement; the other is to solve the problem of low natural circulation efficiency by pump circulation heat exchange, and the pump circulation can obviously improve the water. Heat exchange. The type of solar water heater 3 can be divided into pressure-bearing type and non-pressure-bearing type. (1) Pressure-bearing solar water heater: No matter which split type water heater has a fatal shortcoming, it must use a pressurized water tank, which is the basic idea of ​​all split water heaters, directly testing the sealing performance of the heat collecting part; manufacturing pressure The cost of the water tank is extremely high, there is a safety problem, and the pressure is required to be 7 atmospheres; the circulation effect is not very satisfactory. Solve water circulation and water convenience. (2) Non-pressure-bearing solar water heaters: Currently installed on the roof are non-pressure-bearing water heaters. The water tank has a pipe that communicates with the atmosphere. The height difference between the roof and the home is used to generate pressure when using water. Safety costs, significantly longer than the pressure type. The roof is limited. The types of solar water heaters can be divided into: circulating, direct current and integral solar water heaters according to their water flow direction. The above is what Xiaobian brought to you?
