One of the two plugs is for the pipe heating ribbon, which is usually two-phase, that is, two pieces of iron. The function of this plug is to prevent freezing and defrosting of the pipe, that is, to prevent defrosting. pipe from freezing or The ice melted after the pipes were frozen. The other must be heated electrically in the water tank. Generally, a three-hole plug will be connected with leakage protection. This function is to heat the water tank, which is equivalent to electric heating of an electric water heater. You can use this outlet if you want to take a shower when the sun is not good.
Can the electric heating plug of the solar water heater stay plugged in winter?
There are dual-use solar water heaters.
The water tank of the solar water heater is designed with an installation position for auxiliary electric heating. After beforeIf the electric heater is installed, if the weather is bad and the water temperature in the water tank does not meet the requirements, you can use the auxiliary electric heater to quickly increase the water temperature.
There are two temperature sensors in the solar panel. When solar energy is insufficient, the first sensor 1 of the solar panel comes into play, allowing the primary and secondary coils of A to operate. When the water temperature cannot reach a certain level, when inductor 2 works, the primary and secondary coils BA work, switch 2 is closed, and under the joint action of switches 1 and 2, the The auxiliary electric heater switch is open and the electric heater is set to operate.
The solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high ttemperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based 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.
Detailed information:
Such as: solar water heaters, water boilers, dryers, solar cookers, solar greenhouses, solar rooms, solar desalination devices and solar heating and cooling devices, etc. The production of solar energymic has a higher solar energy conversion efficiency than photovoltaic power generation, but its application is not yet common. In photothermal conversion, solar water heaters currently have the widest range of applications, the most advanced technology and the best economy.Applications.
Photothermal use: It collects energy from solar radiation and converts it into thermal energy by interaction with matter for use. Currently, the most commonly used solar energy harvesting devices include flat plate collectors, evacuated tube collectors and focused collectors. Solar Power Generation: Large-scale use of solar power in the future will be used to generate electricity. There are two main ways to use solar energy to generate electricity:
1. Light-heat-electricity conversion. OtherwiseSaid, thermal energy generated by solar radiation is used to produce electricity. Generally, a solar collector is used to convert the absorbed thermal energy into steam as the working fluid, and then the steam drives a turbine to drive a generator to produce electricity. The first process is light-to-heat conversion, and the second process is heat-to-electricity conversion.
2. Conversion of light into electricity. Its basic principle is to use the photovoltaic effect to directly convert solar radiation energy into electrical energy. Its basic device is a solar cell.
Photochemical use: This is a photochemical conversion method that uses energy from solar radiation to directly split water to produce hydrogen.
Photobioutilization: process of converting solar energy into biomass through plant photosynthesises. Mainly include fast-growing plants (such as firewood forests), oilseed crops and giant algae.

Solar electric heaters are used for supplementary heating in winter. As long as the electrical outlet is located higher on the wall, there is no need to unplug it in winter.
Today's solar water heaters have electric heating functions. When it rains or the weather continues to be cloudy, the electric heater is used to keep the water hot and it cannot be unplugged. It is also very inconvenient to unplug and plug it back in for a while.
