How to choose solar, electric and air energy water heaters?

I am engaged in water heater after-sales, this should be analyzed from all angles, each with its own pros and cons, solar energy:

The cost is relatively high, especially far from the top floor, like your 3 and 6 floors are not far away, but the sun is the most energy-efficient;

Electricity: The cost is relatively low, and the installation is also convenient, but it consumes the most electricity among the three;

air energy; The cost is relatively high, and the installation is slightly more cumbersome than the electricity, because it includes indoor units and outdoor units, which are the same as air conditioners, and good electricity is in the middle of the three.

From the perspective of environmental protection and if there are installation conditions, solar energy should be given priority, followed by air energy, and finally electricity.

I've used all three of them.

Solar energy: The ordinary in-line tube solar water heater used in the suburban house feels okay, but the pressure is not great when taking a bath, because this kind of water heater relies on the height difference of the floor to adjust the water pressure, so there is no solution. The advantage is to save money, the disadvantage is that the maintenance cost is high, what to clean the scale of the water tank, the aging of the water pipe is also a headache, the second is that it can not be used on rainy days, only electric heating, but also power consumption.

Electric water heater: I don't recommend buying a regular water heater, it consumes too much electricity. If you buy an instantaneous water heater, it is the same as gas, ready to use, although the power is 7500w or 8500w, but in fact it cannot reach such a high, generally only three or four kilowatts, and it will cost 3-4 cents to take a bath.

Air energy: Now the home is used this kind, I think it's very good, 24 hours of hot water, electricity consumption is also saved, the family of four, a day or two electricity. Because it is separated from water and electricity, it is also very safe. It's just that the price is a little more expensive.

My house is on the fourth floor, using air energy water heaters, I have used solar energy before, but what about solar energy, it may be suitable for use in summer, and it does not use any electricity, in fact, we don't need any hot water in summer, a little temperature is fine, but it is troublesome on rainy days, and the electricity consumption is high, if it is not used for a long time, it will also cause the pipe to burst, and there is scaling inside, troublesome electric water heater may be used by many people now, but its temperature is actually the same as solar energy, it can reach more than seventy or eighty degrees, and it can cause harm to the human body, so it is not advisable At present, the air energy water heater used at home is safer than the first two, because the water and electricity isolation will not cause ** damage, because the water temperature is also at 60 degrees, energy-saving, open around the clock every day, and the household use is about 1 degree, at least now it is quite safe to use this at home, energy-saving, and it is also very comfortable to wash.

I suggest you install a solar water heater to use safe, energy-saving and environmentally friendly, mainly in the process of use of zero cost (there is sunshine it is brilliant), electric water heater use is more power-consuming and unsafe, heating rod also loves to be bad. Air energy water heater can not be used in winter, spring and autumn also consume electricity in summer can save 60% of electricity, compared to solar energy is more dominant, our unit is installed with solar energy is Tsinghua Kangsheng brand, and later I also installed one in my own home, very good, winter still produces hot water.

Needless to say, a solar water heater, of course.

I haven't heard of air energy water heaters, and I can't give advice.

But solar energy is the same as electricity.

I suggest you use solar energy, the third floor is OK, if you want to save water, you can use solar energy to drain it.

How to say that solar energy saves money and is also safe.

It is recommended to install natural gas, unlimited water, you can match the bathtub, and natural gas is much less than electricity.

Which water heater you choose also depends on which region you live in.

In the northwest, because the light resources are very abundant, the bathing requirements are not too high, and the opportunity for solar electricity to assist heating is very small, so even if the water in the water pipes on the third to sixth floors is wasted, it is still more energy-efficient than the other two.

If you are in the south and the light resources are not too sufficient, it is recommended to use air energy, because when the light is insufficient, the electricity used for electric auxiliary heating is greater than the electricity used by air energy1 3

As for the electric water heater, it is a large power consumer, and there is a hidden danger of leakage, so don't choose it if you can.

You can refer to the key points for purchasing air energy.

Air source, disadvantages, covers a large area, because generally 150-200 liters, and there is an external machine, and due to the limitations of installation, it may be far away from the place of use, and it takes a while to release hot water.

The advantage is that it is more energy-saving, because its principle is the same as that of air conditioning, not to use electricity to make hot water, but to use the process of electric heat exchange, and move the heat from the outside to the water heater, so the energy efficiency is relatively high.

Considering investment and other factors, if you use a lot of hot water and use it for a long time for several years, it is more cost-effective to use air sources.

Solar Water Heater: Advantages: Safe, Energy Saving, Environmental Protection, Economical.

In fact, with the continuous progress of solar energy technology, good manufacturers have solved these problems, such as: the appearance of high-end atmosphere on the grade, any structure of the house can be installed with solar energy, hot water can be produced in winter, can be opened that is, constant temperature water, etc., the solar energy they produce can completely surpass the electric water heater.

It is still recommended that you install solar energy.

Hello, in fact, there is no absolute who is better for solar and air energy water heaters, and they all have their own advantages and disadvantages, depending on your use needs.

1. The disadvantage of solar energy is that it is easy to be affected by the weather and extreme weather, there will be some problems with high-rise solar energy in the space, and the property may not allow the installation of solar energy from the perspective of safety, and now there is a balcony wall-mounted solar energy that can put the collector on the balcony, but it looks abrupt and affects the aesthetics. In terms of weather, if the weather continues to be cold, it is difficult to maintain the hot water demand of the household without sufficient solar energy support. The advantage of solar energy is that it is very clean, environmentally friendly, economical and durable.

2. The advantage of air energy water heater is also the use of clean and green energy "air", air is also an inexhaustible source of energy, and also avoids the danger of electricity leakage and gas leakage. Moreover, the air can work normally on rainy days and at low temperatures, which may be difficult to achieve by solar energy, and there are already areas with minus 45 degrees Celsius using air energy water heaters. The downside is:

First of all, a single unit of air energy is much higher than that of solar energy, and the cost is increased, and he not only needs air energy to drive, but also needs electricity, if the outdoor air Wendy is not high, it is still very power-consuming. Air energy is still relatively common in southern China, and there are some geographical restrictions, which will affect some energy-saving effects in cold areas. The air compressor he used also had a certain life and required some maintenance costs.

I myself use the black porcelain ceramic solar, it is integrated with the building of the solar thermal system, does not affect the outdoor appearance and indoor space, the cost is relatively low, and the building with the same life to ensure your safe use at the same time has the characteristics of heat absorbent coating anti-air exposure and long life.

Now we all use air energy, but it is in a place where there are fewer days.

An electric water heater can produce 150 to 200 liters of hot water with 50 liters of water when it is supplied with air. It highlights that air-powered water heaters are very energy-efficient. In addition, the heating process of air energy water heater is the separation of water and electricity, which eliminates the danger of leakage.

The installation of solar water heaters is more troublesome, because the main body of the solar water heater must be installed outside the house, so whether the solar water heater is installed on the roof or the balcony, it is in a harsh environment, and it is more troublesome to maintain.

Air energy water heaters can be installed in the house or on the balcony, so that the installation and maintenance are also quite convenient. The air energy water heater works without being affected by the weather and can provide hot water 24 hours a day. However, if you are a home machine and you are still in the north, it is recommended not to choose air energy, because the ideal working environment of home machine is -5 to 40.

If it's a commercial aircraft, there's no need to worry. Suggested brand: Spain.

It's still solar energy.,At least solar energy doesn't need electricity.,Everything else is electricity.,Now the electricity bill is not cheap.,My home is to buy Haier's solar energy.,It's still good.,It's okay to use it in winter and summer.,Gray often saves money.。

Air energy But you have to choose a good brand of after-sales.

If it is recommended to install solar energy on the top floor, I personally think that solar energy, air energy, gas and electric energy, you can refer to it.

At present, there are many brands of solar water heaters on the market, various forms of advertising, leaflets, and activities dazzle the people, and the price of solar water heaters with the same volume or the same number of tubes is even double or more, and there is really a bit of an article in it.

1. The main accessories of solar energy - glass vacuum collector tube. It is like an elongated hot water bottle liner, touch the vacuum tube with your hands at the use site, if the temperature is normal and slightly cool, it means that the heat collector tube is a premium product; If it feels hot, it just shows that the quality of the collector tube is very inferior, it is not only absorbing heat, but also dissipating heat, in the winter night can be imagined, the price difference between these two types of collector tube is more than doubled.

2. The quality of the tank liner is very important, many ultra-low-priced solar energy on the market are simple welding, the stainless steel components are seriously damaged, and most of them use flat end covers, which may be deformed with a little pressure, which has a tearing effect on the weld and is very easy to leak, and the good quality is the use of pressure-bearing inner sealing head, and the weld is welded with computer control without discoloration, with a long service life, and of course, the production cost is definitely high.

3. The thermal insulation performance of solar energy also needs special attention when consumers buy, solar energy adopts computer constant temperature foaming equipment, and imported polyurethane is foamed as a whole. The ultra-low-priced solar energy on the market is foamed by hand, the cost of polyurethane is too high, they are often insulated with the equivalent of packaging foam, soft or particularly hard, once the surface is broken, the inner layer strength is very low, and there are debris falling out. Touching the backlight of the outer box shell with your hand at the use site, it feels very hot, while the solar feels at room temperature, which indicates that the thermal insulation performance is particularly good.

4. The production process can also see the advantages and disadvantages of solar energy quality, and the solar energy production process is fine, which seems to be a handicraft. Many low-priced solar energy, and even some solar energy, which is mainly supported by advertising, are made in a crudely process, and it is entirely conceivable what its intrinsic quality is.

5. The bracket is a very consumable material, like a solar vacuum tube that can stand on the person without deformation. And those ultra-low** solar energy, when you want to step on it, you must first ask for the advice of the business, otherwise you can only move home if you step on it.

Hongyangyu solar water heater is good, beautiful in appearance, also very easy to use, and affordable.

2012 China's Top 10 Solar Brands 1, Huangming Solar 2, Four Seasons Muge Solar 3, Cicero Solar 4, Sunyu Solar 5, Sunle China Famous Trademark 6, Huayang Solar 7, Yijianeng Solar 8, Michelle Solar 9, Linuo Rite Solar 10, Tianpu Solar.

Seriously, as long as it is cheap, the production process is the same, the cost is the same, the electric heating is not cost-effective more than 3,000 watts, the wires must be thick, not pretending to be good, in fact, many brands of accessories are small factories to provide them with accessories, big factories and big brands have a big sales platform, can sell a **grid, I think it is still cheaper and more cost-effective, to ensure that there will be no problems in 10 to 15 years.

It sounds expensive, but it's actually about the same, since he can sell it, he can use it, the difference is whether there is electric heating.

Mainly vacuum tubes and flat plates, relatively speaking, the current use rate of the flat plate is a good point, but it is the most expensive, vacuum tube brand: Midea, Wanjiale, Sun Rain, Huangming, Linuoruite, Four Seasons Muge and so on.

Brands of tablets: Hailin, Haier and so on.
