40 degrees.
1. In winter, if the thermal insulation setting of the solar water heater is high, the water heater will stay in a high temperature state for a long time and waste energy. The temperature is set at 40 degrees, which can effectively reduce energy waste and also meet the needs of domestic hot water usage.
2. Setting the insulation temperature of the solar water heater to a high temperature will cause the pipes and components inside the water heater to be kept in a high temperature state for a long time, accelerate aging and shorten the service life. life. life. Setting the temperature to 40 degrees can effectively extend the life of the water heater. Therefore, the insulation setting of the solar water heater is 40 degrees.
The highest water temperature in a solar water heater is 100°C. From the first stages of the design of the chsolar water heater, the problem of combustion and aging of components has been 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 filling function should be turned off or the water in the solar water heater can be drained.
