Due to the need to go out of the solar water heater for a long time how to deal with?
The solar water heater for several days without water are generally more hot water, more than 70 DEG C, especially in summer sunny weather for more than 2 days, the water will boil, to be properly cooling at night, keep the water temperature at 60 DEG -70 DEG region for a long time, and this is an excellent temperature region of bacteria breeding water temperature, therefore, such as several days or without water, poor water quality, bacteria, to be discharged, do not take a bath or used for boiling water drinking water bath, so detrimental to the skin, long-term use of this water bath will cause skin disease.
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
If the home to buy solar energy, temporarily do not have to use it, it is recommended that you use blankets, carpets or quilts cover the vacuum tube to avoid the sun, so there will be no problem.
Vacuum tube solar 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 thermal effect and film molecular structure changes due to air drying to reduce the period of life.
