Want to buy a solar water heater, a family of five. Would like to know how the solar energy work, I heard that they have to use electricity? Power consumption? How much does it cost to buy a suit? Expert guidance.If it is rainy weather, you can also use it? How much water temperature can reach?
Is not the normal operation of solar power, but in the rainy days continuous, start power consumption of electric auxiliary heating, electric auxiliary heater is 1500 watts, is the general temperature control, electric heating temperature is about 65 degrees, the highest temperature of the solar sun rises by 100 degrees. The market generally buy a vacuum tube type solar vacuum tube solar heating principle is in the water, on the thermal siphon vacuum tube hot water to the water tank, and the cold water in the water tank into the vacuum tube, these are microcirculation.
Simple choice judgment method1, look at the appearance of the fine workmanship: water tanks, stents, screws, insulation materials processing2, see [support firmness (stent thickness), corrosion resistance (material), stability] can also Diandian weight3, the thickness of the water tank (tank Diandian weight, average person Dianzhe slightly heavy)
4, the color of the vacuum tube (single, all) whether there is no color difference, is the same. 5, price: 58 yuan (including 100-120 diameter pipe installation materials: on pipes, insulation materials, overflow pipe, electric heating wire, the upper and lower joints, indoor water supply system, a total valve, without additional function: electric heating, microcomputer, with tropical etc.)6, capacity: insulation material removed about 5 cm (see section outlet side position, its lower end to the bottom of the tank is the thickness of the insulation layer) is the volume of the water tank is cylindrical, the volume, the user is basically the amount of water available.
