When solar energy is not used, is it better to fill it or empty it?

Drain the water.

If the solar water heater is not used in winter, the water from the solar water heater should be drained, the valve closed and the interior plug disconnected to keep the exterior water lines free of water and not frozen. Prevents water pipes from freezing and cracking due to low temperatures and lack of water circulation.

If the solar water heater is filled with water in winter, when the temperature is too low, the water in the pipes will easily freeze and freeze the pipes. In severe cases, the solar water heater will freeze and. crack.

Detailed information:

< p>A heater that converts solar energy into thermal energy and heats water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into solar water heaterss vacuum tube and flat panel solar water heaters depending on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.

Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.

If the solar water heater is not used in winter, the water must be drained.

If you don't need to use the solar water heater in winter, first blow out the water from the water heater, close the valve and unplug the inner plug so that the watercontinues to flow smoothly and the outside water pipes do not freeze. Prevents water pipes from freezing due to low temperatures and lack of circulation.

If the solar water heater is filled with water in winter, when the temperature is too low, the water in the pipes will freeze easily, causing the pipes to freeze. In serious cases, the solar water heater. freeze and crack.

On sunny days, the solar water heater can be used normally; When the temperature is below -5℃, it is better to use the water heater several times a day.

Solar water heater in winter:

< p>1. In winter, when the temperature continues to drop below 0°C, it is necessary to turn on anti-freeze devices such as electric heating tapes for preheating protection. Especially in cold northern regions, where the temperaturere is always below zero, anti-freeze devices will be installed for heating.

2. When using solar water heaters in winter, determine when to add water based on how cold it is.

3. If there is no installed solar water heater, tropical water heater, etc., if the weather is cold, you can open the hot water nozzle or faucet, place a basin underneath, loosen hot water. slightly the outlet valve and let it drip slowly, in order to maintain the flow of water in the pipe and avoid cracking in the frozen pipe.
