Are there more and more users using solar water heaters, but many users have not cleaned water heaters for years. If the water heater is not cleaned for a long time, a large amount of scale of the solar water heater will be generated, and the service life of the water heater will be significantly reduced.
First: scale of the solar water heater will reduce thermal efficiency
Because the scale has a low thermal conductivity, thick scale is a thermal resistance, which reduces the heat transfer efficiency of the water heater.
Second: scale of the solar water heater will reduce the circulation of the water heater
After scaling in the vacuum tube of the solar water heater, the scale prevents the water flow inside the water heater from circulating, which will cause the heat in the vacuum tube not to be transmitted inside the water tank, resulting in slow heating.
Third: scale of the solar water heater will make the sensor ineffective
After scaling in the vacuum tube of the solar water heater, the temperature sensing element inside the sensor cannot sense the change of the external water temperature in time, so that the displayed temperature is lower than the actual water temperature.
