Polyurethane foam insulation type 250L pressurized solar water
heater
Are there more and more users using 250L pressurized solar water
heater, 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 250L pressurized solar water heater will be generated,
and the service life of the 250L pressurized solar 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.
