Add it once every 2-3 years
The thermal oil inside the solar hot water system is used as heat transfer fluid, so thermal oil must be added depending on the life of the fluid. generally 2 to 3 years. It is only necessary to add sunscreen oil once. But it also needs to be added according to the actual situation. When using the solar hot water system, leakage will occur in high temperature and pressure in summer. In this case we also need to add it again.
Heat transfer fluid.
The collector is not in direct contact with the water in the conduit, but conducts heat energy to the condensing end through the conductive liquid, and the condensing end conducts the thermal energy in the duct, which also prevents the duct from generating scale. The water heater conductive fluid is a professional antifreeze agent and canbe used normally in low temperature conditions. It can produce heat in two minutes under the sun.

Remarks:
p>When taking a bath, if the water in the solar water heater is used up and the person has not rinsed, you can pour cold water for a few minutes and use the principle of cold flowing and hot water. floating water to supplement the hot water in the vacuum tube. Once you get out, you can take a shower.
After the water heater is installed and fixed, non-professionals should not move or disassemble it easily to avoid damage to key components. No debris should be placed around the water heater to eliminate the risk of hitting the vacuum tube. . Check the exhaust holes regularly to avoid inflation or deflation of the water tank, during regular cleaningof the vacuum tube, be careful not to damage the lower end of the vacuum tube. For solar water heaters equipped with auxiliary electric heating devices, take special care. should be paid to the water supply to avoid dry burning without water.
