How does a solar water heater heat without sunlight?

When installing a solar water heater, an additional electric heating device must be installed. Electric heating can be used when the sun is not shining, and auxiliary heating can also be used in winter. “Air power” also uses electricity, but is more energy efficient. Nowadays, water heaters of the same energy are generally equipped with additional electric heating tubes;

First of all, this is to increase the temperature of the outlet water. when there is little sunshine;

The second is to prevent the water in the water tank and water pipes from freezing and cracking the water tank and pipes of water during the northern winter. Therefore, hot water can be supplied even. when there is no sun, but heated only by electric heating pipes.

The solar water heater is a device that converts solar energy into energye thermal, heating 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 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.

Daily maintenance

1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe when using it. the first time, you can turn on the tap first. Get rid of the clutter.

2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.

3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.

4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, pleaseTurn on the cold water first, then the cold water. hot water to avoid burns.

5. There is usually a filter device at the outlet of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow and smooth it. out of water.

6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises.

You can also use a hair dryer to blow out the water pipe, or wrap a towel around the water pipe, then slowly pour it with warm water. Don't cook it on fire, don't hit the pipe or. scald it with boiling water, as this will damage the pipe. Multiple freeze blockages can easily cause pipes to freeze and crack. Insulation measuresThe pipes must therefore be reinforced.

7. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. Users can also do some disinfection work themselves, such as purchasing chlorine-containing disinfectants. Pour the agent into the water inlet, let it soak for a while, and then release it, which can achieve a certain disinfection and sterilization effect.

8. Solar water heaters need to be cleaned inside the vacuum tube every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect.

9. If the solar water heater is equipped with a special instrument, please pay attention to lightning and electricity protection. Do not take a shower and unplug the electric heater during lightning.

Which is more economical and practical, the electric water heater or the solar water heater?

In general, the water The temperature of solar water heaters in winter is 40 to 60 degrees, mainly It always depends on the lighting conditions of the day; if there is no sun, you can also use the electric auxiliary heater. It only takes 30-40 minutes to heat up, which is equivalent to an electric water heater! The time is shorter than ordinary single warehouse, and it is more economical!

It's actually not absolute. It mainly depends on the price, comfort and possibility of installing the site. From low cost to high cost, consider: electric water heater, solar and air. energy.

High to low electricity bills throughout the year: electric water heater, solar energy, air energy (the prerequisite here is that the winter is long and a heatsolar electric booster will be used)

Electric water heater The cost is the lowest, but it only uses electricity all year round and the heating time is roughly 30 minutes for a person to wash. The advantage is that there are no requirements. facility. If you choose to buy, consider choosing big brands, like Changhong, Midea, etc. !

The advantage of solar water heaters is that they save electricity. When the sunshine is good, they will save a lot. However, if lighting conditions are not good, electric supplementary heating is necessary. The warehouse is used, the power consumption will be relatively large, but it can use Sancang solar energy equivalent to solar energy + electric water heater. It's more profitable if there is a lot of sun!

In summary, as long as there is a place to install solar power, I personally recommend itchoose a three-bay solar water heater. This saves money and you don't have to worry about water temperature. The after-sales rate is lower than that of a single warehouse, and water and electricity are practically separated!

The above is my personal working experience in Hunan Jiangyue New Energy (14 years of solar and air power machine accessories wholesale) and is for reference only.

Recommended "Dr. Sun" solar power (combination of solar power + electric water heater, lower electricity bills), three barrel model (no need for water level detection probe and solenoid valve), rapid heating and hot water use in rainy days, and the after-sales rate is also greatly reduced, saving time and energy. This model only takes 20-30 minutes to heat without sunlight, while a single warehouse takes 2-3 hours! p>
