The solar water heater without water becomes bad
If you do not use it for a while, it is recommended that you use a blanket, carpet or quilt to cover the vacuum tube to avoid sun exposure.Other parts of the air drying will not cause problems.
There will be effect ~ solar vacuum tube air drying is not good, because the tube wall temperature can reach four hundred degrees, so the air drying vacuum tube will direct sun differential blasting, good vacuum tube as Linuo, will reduce the life, such as this can be used for twenty years, will result in changes in fruit and molecular film the structure of thermal effect due to air drying, reduce the duration of life.
Vacuum tube solar water heater with high efficiency in the summer, sunny weather conditions, less than two days water temperature can reach the boiling point, if a long time without water, such as travel, tourism, to make the water a long time at high temperature and high pressure conditions, will accelerate the aging of the sealing ring, accelerated aging, polyurethane shrink, sometimes not exhaust smooth, too much pressure will make the tank expansion bad, will shorten the life of furring, water tank. Therefore, if you are not at home for a long time, you should arrange for others to put hot water on the cold water, or in the vacuum tube collector placed on the cover to block the sun, to go home, and then remove. If you do not use it for a long time, you need to cancel the electric heating setting to avoid wasting electricity
