There are several specifications of solar water heaters

1. From the heat collection part:

1. Glass vacuum tube solar water heater,

Glass vacuum tube solar water heater is mainly powered by solar energy, supplemented by electric energy.The method of use allows the solar water heater to work normally all year round, and the efficiency is still relatively high when the ambient temperature is low.

2. Flat Plate Solar Water Heater

The flat plate solar water heater is easy to integrate into the building and its thermal performance is also very stable. However, because there is no vacuum inside the cover and the thermal insulation performance is poor, the heat collection performance is poor when the ambient temperature is low and consumes relatively much power when the use of auxiliary heating. Thermal efficiency is lower when ambient temperaturente is low or when the outlet water temperature needs to be high.

2. Classification based on structure:

1. Compact solar water heater,

The compact solar water heater inserts the vacuum glass tube directly into the water tank. and uses Circulating heated water raises the temperature of the water in the water tank. It is the most classic solar water heater on the market.

2. Split type water heater,

The split type water heater separates the collector and the water tank, which can greatly increase the capacity of the solar water heater. use the falling water working method and expand the scope of use.

Detailed information:

< p>Tips for purchasing a solar water heater:

1. Look at the quality of the vacuum tube.

The vacuum tube is a key part of the water heater when purchasing. For obCarefully serve the glass tube coating inside the vacuum tube, its color is usually black, dark blue or dark gray. A good quality coating has a uniform color, no scratches, peeling or peeling on the film, there are no stones on the glass and the backings are placed correctly and will not come off.

2. Look at the insulation layer and the covering.

The processing technology has a layer of insulating material between the outer shell and the tank liner of the solar water heater, which plays an important role. very critical role in hot water insulation. Function, the service life of polyurethane insulation materials can reach more than 10 years. The inner tank is where the hot water is stored and its thickness is approximately 0.5mm.

3. Select the water tank capacity.

Household bathing water is low If household water consumption includes cookingne, total water consumption can be estimated on the basis of water per capita. consumption of 40 L; domestic solar water heater water temperature in winter Usually calculated based on 50 to 60 degrees, the water capacity of the water heater is converted. The actual purchasing decision depends on the condition of the water heater.

Solar energy is an industry with low requirements technical, so why will there be such a difference in price?

1. Businessmen are looking for huge profits, and the same goes for the solar energy industry.

2. means that the profits with low prices are low, not necessarily, they In the selection of materialsThe quality is poor and the price is low. They prioritize quantity;

3. Solar thermal products are also divided into high-end and low-end, mainlymainly in the selection of materials, such as the interior. The more expensive tanks use stainless steel and the lower end ones use stainless steel. The ends are made of stainless iron or even cheaper metals, and the insulation layer is made of inferior foam materials or even worse junk materials. , etc. The price difference between their materials is much less serious than the difference between their final sale prices, but there are unspoken rules in every industry, you know.

4. The advantage of solar energy is that you can invest once and make long-term profits. However, in fact, this may not be the case. Many solar energy products have quality problems. Metal cables are not properly secured and fall; the insulation layer is not good, it cannot be used in winter, it leaks, etc. It's hard to say. Maybe some people use it well after buying it, while others may have problems a few days after buying it.

5. If you want to buy solar, just buy one that is about the same. There are pitfalls if it is too expensive or too cheap. You can only buy one that is approximately the same.

6. If you don't buy solar, the same applies to gas and electricity, but it depends on whether you use it correctly.
