You can put one on first. small amount of water to let the water flow into the pipe, then rely on the water temperature to increase thepipe temperature. Note that the lower the temperature, the more water must be released, to prevent water pipes from freezing.
2. Water supply according to different weather conditions
When the temperature is not too low (5-7 ℃), after using water at night, if there is still water hot water, Then the solar water heater should be filled with water to lower the water temperature in the water tank, so that there will be less heat loss that night if the temperature is very low, the water should be refilled the next morning, which will help; prevent the pipes leaving the water heater from freezing.
3. Antifreeze and pipe insulation are essential.
Solar water heaters should pay special attention to pipe antifreeze, especially insulation measures for the water tank of the heater -water. and water pipe are connected. Well, usually oneinsulating pipe is two meters long and it is best to bind the joints with adhesive tape.

General solar water heaters used at home are equipped with heating and antifreeze devices, but many people use them after pipelines. freeze. Allow it to defrost. In fact, it will not only delay the use of hot water, but also damage the lifespan of solar energy. Usually the correct way to use it is that when the temperature stays below 0℃, we need to turn on the antifreeze device so that it can be preheated and protected.
