The vacuum tube of the solar water heater in winter no, there is no water or will break up the sun?
Antifreezing measures:1, in case of low temperature weather or without a solar water heater needs to be long, the water valve of water heater and water heater vent closed on the water in the pipeline, lest because the temperature is too low, lack of water circulation caused by pipe donglie.2, when the temperature is lower than 0 DEG C in winter, it is necessary to open the electric power with the anti freezing device such as tropical, preheating protection. Especially in the northern cold region, when the temperature is always at minus, it is necessary to open the heating antifreeze device.
Because the solar energy water heater vacuum tube and the water tank have the protection measure, therefore the water heater water after opening will not be frozen.
3, the use of solar water heaters in winter, according to the degree of cold weather to determine the time to add water.4, no solar water heater installed with tropical etc., in case the weather is cold, can open the hot water sprinkler or tap, put a basin of water under the water valve release point, which slowly dripping, to keep the water in a pipeline flow, to prevent cracking pipes.
