Solar water heater vacuum tube in the summer without water easily broken? Is my water heater function is bad, the water tank above the water, so the summer, the vacuum tube is not easy because the temperature is too high and burst?If broken, the vacuum tube can be replaced by a new one? How much is a pipe in general?Our landlord is very concerned about this, so I understand.Also, can I use a piece of cloth to cover the heat sink so that it doesn't burn.
Not burstSolar vacuum tube national standards need to pass the air drying test.If there is no water in the vacuum tube, in a sunny day under the sun, the vacuum tube in the air drying state, this temperature is generally 250-300 degrees (GB 190 degrees). For a long time at high temperature, vacuum tube vacuum performance is not as good as before, vacuum tube heat loss becomes larger, the heat absorbed easily lost, so that the pipe affect the overall hot water temperature is not good. It is recommended to cover the vacuum tube with a cover, and check whether the vent is unobstructed.
If it weren't for the summer, the temperature would not be higher, not to worry about the problem. In the summer is approaching, we must do a check on the water heater, a maintenance, to increase the service life and life.
However, if a long time in the air temperature, vacuum tube vacuum performance will be reduced, vacuum tube heat loss becomes larger, the heat absorbed easily lost. If there is no water in the tube in the summer, cover the vacuum tube and check whether the vent is open
The vacuum tube of the solar water heater is not damaged in the absence of water in summer.Vacuum tube solar has a strict production standards, in the sun in summer, if there is no water in the vacuum tube, the highest temperature is about three Baidu, and the production of the vacuum tube need short drying test, temperature should be higher than this several times
