Buy a solar water heater recommended 100

If you use it for three people, you can use a 58 pipe diameter, 18 pipes, 160 liters, or 20 pipes, 180 liters.

As for the quality, we should pay attention to the following aspects:

1) Look at the size of the water tank The size of the water tank is usually 450 470 500 The size of the water tank is not the same** is not the same Generally 470 Then look at the inner tank material of the water tank is generally 304 stainless steel Then look at the thickness of the insulation layer of the water tank Whether it is more than centimeters.

2) Look at the tube The vacuum tube is best to choose the three executives who are red in the tube, don't listen to the store fooling and saying that other tubes are good.

3) Look at the bracket of the solar energy The best bracket is the bracket of the aluminum profile.

4) Look at the distance between the two vacuum tubes, so that the hand can be placed to the back of the hand.

5) Look at the installation accessories of solar energy, and it is better to choose copper accessories.

6) Look at the solar meter Don't believe the brand logo on the meter That is all doable, and there is no solar brand to do the meter Most of them are self-matched by the store, and it is best to use TMC brand meters.

7) Look at the service of the store There is a good service will be more worry-free, you can look at the installation record of the store, and randomly hit a few ** to understand the service.

There are many solar brands, As for the ** aspect, consumers are very rational now If three or four thousand pieces of hot water can be produced, two or three thousand pieces can also produce hot water, why buy three or four thousand? I think those under 3,000 yuan can meet the above seven requirements can choose.

I'm doing heroic sunshine, you can take a look.

Paigson e e e era department, all good, a thousand to two thousand me. Now I am still doing 1000 back 200, 2000 back 400, according to your own needs enough to buy.

Hua Yang, now there is a blue sky operation, and the 2,003-4 used by 3 people will be all done.

Zhengda Solar Marshal Gold Series All-Steel Series Just search and look at the information.

The emperor in my house has two or three thousand, and three people will be enough if they are washed well.

Solar water heaters are environmentally friendly and do not require electricity, but the initial investment cost is relatively high. So is a solar water heater worth buying? PChouse will explain it to you.

Solar water heaters have great advantages and are cost-effective in the long run.

1. High-tech products, copper-aluminum anodized composite core or all-copper core, high surface treatment technology, good heat transfer performance, strong heat absorption capacity and large water production.

2. The system has good thermal insulation performance, large heat storage energy, and the thermal insulation water tank has a water storage function, which can meet the centralized use of hot water by a large number of personnel, and can also be used as an emergency water source when the water is stopped.

3. The solar water heater system is fully automatic and static, without special supervision, no noise, no pollution, no leakage, fire, poisoning and other dangers, safe and reliable, environmental protection and energy saving.

4. It has the function of sewage purification, and the water source is clean and pollution-free. The vacuum tube solar water heater has good thermal insulation performance and strong frost resistance.

1. Not cost-effective. Solar water heaters are too dependent on good weather to use, and if in the northern region, when it comes to winter, solar water heaters simply cannot be used.

2. Although some solar energy can be energized to make up for the situation that the weather is bad and cannot be heated, it is not as good as the electric water heater. There are many conditions for installation, and it is more troublesome, if there is a failure, maintenance is not worry-free.

The solar water heater worked well.

Solar water heater is a heating device that converts sunlight energy into heat energy, heating water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, mainly vacuum tube solar water heaters, accounting for 95% of the domestic market share.

Principle:

During the heat absorption of a vacuum tube water heater, the solar radiation passes through the outer tube of the vacuum tube, is absorbed by the heat collection coating, and then transmits the water to the tube along the inner tube wall. After the water in the tube absorbs heat, the temperature increases, and the specific gravity decreases and rises, forming an upward power and constituting a thermosiphon system.

As the hot water moves up and is stored in the upper part of the tank, while the cooler water is replenished along the other side of the pipe, and so on, the whole tank of water rises to a certain temperature.

Plate water heater is generally a split water heater, and the medium is naturally circulated in the collector plate due to thermosiphoning, and the heat of solar radiation in the collector plate is transmitted to the water tank in time, and the heat is transmitted to the cold water through heat exchange (jacket or coil) in the water tank. The medium can also be transferred by means of a pump circulation.
