1. Typically, dual hot and cold water taps (or thermostatic mixing valves) are installed and pressurized wall-mounted solar water heaters are used.
During the hot summer, if the water temperature of the solar water heater exceeds 80 degrees, it will affect the life of the water heater because scale will form, so it is necessary to release hot water; in time and add cold water (after using the hot water at night), do not rush to refill the water, in case the solar tube temperature is high in summer and burst. Generally, it is safest to refill the water in the morning. ), do not let the water temperature be too high. If necessary, cover part of the vacuum tube with straw curtains, bamboo curtains, etc. to reduce heat absorption.
2. Little knowledge: How to solve the problem of hot and cold solar water heaters in summer?
(1) Cause: La plupart solar water heaters are falling water type (open type), which is a pressureless system, and the tap water is under pressure. A non-pressure system and a pressurized system are combined, allowing two water jets of very different pressures to merge, and must be instantly mixed in proportion at a temperature of 38-40° suitable for showering. Our hands are not precision instruments. , and the movements are slightly larger. It will be hot and cold.
(2) Solution
Solution 1:
There is currently a thermostatic water mixer on the market, which can adjust the temperature to a certain temperature . Generally, it is 38℃ in winter and around 35℃ in summer. When purchasing, pay attention to the distance between hot water and cold water, the distance between thermostatic mixers is 15cm, and pay attention to the inlet positions of cold water and Hot water.
Solution 2 :
Use a pressurized wall-mounted solar water heater. The outlet pressure of the pressurized wall mounted solar water heater is almost the same as the inlet pressure. tap water pressure. Two matching pressure systems are combined and the water temperature is easily adjusted.
The highest water temperature in a solar water heater is 100°C. From the first stages of the design of the solar water heater, the problem of combustion and aging of the components was taken into account. water heaters will not burn out.
However, it is recommended not to maintain high temperatures permanently. If the temperature remains high for too long, it will accelerate the aging of the water tank coating and various accessories. Therefore, it is recommended that when the solar water heater is not used for a long time, the automatic water supply function should be turned off or lwater from the solar water heater can be drained.
