Introduction Can solar energy be used for electric heating? Solar water heaters can use electric heating. Nowadays, many solar water heaters are photoelectric compatible. When in use, simply press the electric heating button to heat the water.

Can solar energy be used for electric heating?

Yes.

Solar water heaters can use electric heating. Nowadays, many solar water heaters are photoelectric compatible. When used, pressing the electric heating button can quickly heat the water temperature. In addition, you can also install a direct electric heater in front of the water outlet, or install an additional electric heater and install it in the heating hole of the water heater.

Solar electric heater is a solar water heater with auxiliary electric heating function. It uses solar energy as the main source and electric energy as a supplement. The method of using energy allows the solar water heater to work. normally all year round and all day, and efficiency is always high when the ambient temperature is relatively high. Its disadvantages are that it is relatively larget large, the glass tube is fragile, scale easily accumulates in the tube, and it cannot work under pressure.

No matter where you are, there are clouds, rain, snow and a lack of sunlight every year in winter. In this climate, hot water is mainly heated with electricity (some products are heated with gas). On average, more than 25-50% of hot water must be heated entirely with electricity each year (this varies by region). , and there are many cloudy days). The actual electricity consumption in the region is even higher

Detailed information

Precautions for using solar water heaters<. /p>

1. Stored water should be discharged regularly depending on local water quality conditions. The drainage time can be selected in the morning when the collector temperature is relatively low.

2. The surface of the solar water heaterire should be wiped regularly depending on the amount of dust in the area, it can clean itself when it rains, and keeping the water heater surface clean can achieve higher heat collection efficiency

3. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using a solar water heater, please turn on the cold water first and then the hot water to avoid scalding.

4. There is usually a filter device at the outlet of the faucet. Scale and debris in the water line accumulate in this net, so disassembly and cleaning must be carried out regularly by yourself.

5. The interior of the vacuum tube should be cleaned every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect

6. If the solar water heaterst equipped with special instruments, pay attention to lightning protection. Do not take a shower and unplug the electric heater during lightning.
