What should I do if the electric heating area under the large drum of the solar water heater is leak

Introduction What should I do if the electric heating area under the large drum of the solar water heater is leaking? First of all, if there is water leakage from the electric heating rod, do not use the auxiliary electric heating function to avoid leakage during use.

What should I do if the electric heating area under the large drum of the solar water heater is leak

First of all, if water leaks from the electric heating rod, do not use the auxiliary electric heating function to avoid the risk of electric shock due to leakage during use.

It can be seen from the picture above that the water heater has been used for a long time and is badly corroded. If the solar energy is normal (the temperature increase of the vacuum tube heater is not much different from when it was first purchased), you can continue to use the solar heater if the solar heating speed is significantly slower than before and take corrosion into account. of the water tank and the bracket, if the corrosion is significant, it is recommended to replace the solar energy water heater.

If there are no major problems elsewhere, disassemble and inspect. Firstly, determine the water temperature in the solar panel, make sure it is not high (to avoid burnes during disassembly) and drain all water from the solar panel. Remove the electric heating tube to replace it. Normally, there are two ways to fix the electric heating tube, one is fixed by sealing ring, without screws to specify the heating tube, the other is fixed by screws, you can pull; it came out forcefully with screws opened by screws. Check the sealing ring. Due to water leakage, the sealing ring must be broken. Remove the sealing ring and buy a new one. At the same time check whether the electric heating rod is scaled. If the scaling is significant, it is recommended to clean or replace it. If the electric heating rod is heavily scaled, the scale in the vacuum tube must also be large. Find a professional solar installer to clean it depending on the situation.

To reduce the risk, if electric heating is not used frequentlynt, you can remove the electric heater and use a plug to block the electric heater hole.

Is the water in the insulation barrel of the solar water heater afraid of freezing?

Different solar water circulation and heating methods are different

Domestic solar water circulation mode

Type of vacuum tube: water in the water storage tank, when the water temperature increases, the hot water increases and the cold water decreases, and the cycle continues until the water temperature increases in the water tank is maintained.

Wall-mounted type for balcony: the water in the water tank is stationary. The principle of water heating is to absorb heat and heat the fluid through the collector located on the balcony, and heat the water through water circulation. the way.

Water circulation and heating mode of the solar hot water project

Direct heatingt without fluid: The water in the water tank continuously circulates in the collector and heat is continuously transferred to the water. in the water tank. The principle of all water is that heat rises and cold falls.

Fluid heating type: The fluid continuously circulates in the collector when passing through the water tank, the fluid pipe inside is shaped like a coil, and the heat is transferred to the water in the water tank. the coil. The water in the water tank also circulates constantly. This cycle requires a circulation pump to circulate water throughout the solar system. The purpose of the gas is to keep all the water in the system at a certain temperature.

The water inside will freeze if it's cold, but only if there is no sunlight for at least 15 days. Vacuum tubes will not freeze because they are under vacuum, and barrels generally will not freeze because they have an insulating layer. Unless the eIf the inside has been exposed to the sun for a long time, I think it will freeze. You'd better wrap the tube going down, because it won't freeze and crack easily.
