Every March and April is the peak period of decoration since the beginning of spring. In addition to various building materials, home appliances are also a concentrator for purchase. In terms of location, many families use solar water heaters, which are environmentally friendly, energy-saving and safe. However, many friends also encounter various problems with solar water heaters. Today, the author will introduce to you that March and April every year is the peak period of decoration since the beginning of spring, In addition to various building materials, home appliances are also a concentrator for purchase. In terms of location, many families use solar water heaters, which are environmentally friendly, energy-saving and safe, but many friends have also encountered various problems with solar water heaters. Today, the author will introduce to you:

generally, 20-40kg hot water is required for each person to take a bath, and each vacuum tube can heat 6.5kg of water, The required water heater capacity can be estimated according to the household population and habitual bathing water consumption

in areas without tap water, solar water heaters should be used. Generally, water can be supplied by water pumps. In addition, an auxiliary water tank is added at the same height as the solar water heater to store cold water so that it can be mixed with cold water during bathing

it may be because the exhaust hole is blocked. When water enters or discharges, the internal air cannot be immediately discharged or supplemented, forming an internal and external pressure difference, causing the water tank to burst or deflate

the relationship between the size of the water tank and the number of vacuum tubes

generally, the water heater is designed according to the hot water temperature required for bathing. Generally, the design water temperature range of solar water heater is 400c~900c, and roughly 6.5kg of water is heated by each pipe

what should be paid attention to when filling the vacuum tube solar water heater

because the temperature in the vacuum tube can reach about 2500C when it is exposed to the sun, there is no water in the water tank or the first water filling must be carried out before sunrise or half an hour after sunset

how to judge the advantages and disadvantages of solar water heaters

solar water heater is a kind of solar heat utilization. The whole water heater includes heat collection part, heat storage part and support part. The main basis for judging the advantages and disadvantages of the heat collecting part is the absorption rate and divergence rate of the heat collecting element, which is related to the material and manufacturing process

the heat storage element is the warehouse of the water heater. Its quality assurance includes two aspects: no leakage and heat preservation. The tank welding method is very important. The strength of welding and whether the material is anticorrosive are the key to the quality of the tank. In addition, the thermal insulation material determines the thermal insulation performance, and the thickened thermal insulation layer must be used in cold areas

the support supports the operation of the main engine and ensures the correct position of the heat collecting element. It needs to have the same service life as other components of the main engine, which requires good strength and anti-corrosion ability. Its advantages and disadvantages can be judged by visual inspection of its material, thickness and surface treatment
