Buy a solar water heater, is it cost effective to buy a solar water heater

My insight: Tsinghua has the best sunlight, fast heating, and long heat preservation time.

Others such as Huangming, Four Seasons Muge, Brilliant and so on.

Look at you, it's not too short to know. Just look at what people are saying. Start with well-known products.

The reason is that the well-known ones are relatively strong, and the possibility of bankruptcy is relatively small. In addition, the well-known brands of ** merchants are more powerful. Generally speaking, the margin collected by the manufacturer is much more than that of the unknown one, so the after-sales service is relatively good.

It's all relative. Unknown brands are not necessarily of inferior quality to well-known brands, and some brands are even better than well-known ones. But you're not an expert, it's hard to tell.

There is also a very good after-sales service. All you can choose now is to look at which one of the surrounding areas has been using the solar water heater for a long time. And the after-sales service is also good, of course, it is not as good as the after-sales one.

It is most accurate to inquire about it. Just buy that brand. Generally speaking, the maintenance rate of solar water heaters is very low.

Most of the repairs are on the accessories, mainly the electric heating and probes.

20 pipes will do. Buy Sanglo digital bar, fully automatic and easy to use, anti-freezing in winter, electric heating is very easy to use.

Three mouthfuls, 150L can be enough, it is said that the actual value of 150 is less than this, and there is water in the vacuum tube.

If the brand is not specified, it must be a regular manufacturer, not necessarily a famous brand, the famous brand is too expensive, that is, it has been used for more than ten years and is an advertising fee.

After-sales should be good, solar energy is not like electrical products, after-sales are not formal, even if it is a famous brand (there may be a darker after-sales and a higher asking price). The key depends on whether the after-sales boss is really ---

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.

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.
