Solar water heater does not add water, the sun will not be bad in summer
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, so there will be no problemOther 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 life period.
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 no longer at home, others often should arrange hot water or cold water in the vacuum tube collector is placed on the cover from the sun, stay home, and then removed. If the winter is not a long time. You need to cancel the electric heating setting, to avoid wasting electricity.
