Solar pressure water heaters are solar water heaters that use pressurized water tanks. This pressurized water tank can provide strong water pressure. It directly uses the water supply pipe network pressure as the hot water outlet pressure, making the hot water pressure equal to the cold water pressure. This pressure solar water heater solves the problem of ordinary roof-type solar water heaters that rely on gravity to lower the hot water pressure. It not only has high water pressure, but also has easy temperature adjustment and will not cause temperature changes. due to the uneven pressure of hot and cold water, the bathing experience is more comfortable.
What are the advantages and disadvantages of pressurized solar water heaters
Pressurized and supercharged solar water heaters are better.
1. Avadvantages and disadvantages of pressurized solar water heaters: Advantages: The principle is that when hot water comes out, cold water can be replenished into the water tank at any time and water can be supplied. at any time, the pressure of the water outlet is the same as that of tap water. Disadvantages: It consumes more electricity. Electric heating should be used frequently. The pressure type uses heat pipes for heating. Water is not leaking in the pipes. The transmission fluid is used to conduct the contact temperature of the heating plate. in the water tank barrel is very high. It is very alkaline in Beijing. It is easy to spread and burn.
2. Advantages of pressurized solar water heaters: superconducting heat pipes conduct heat in one direction and have low heat capacity, so the starting temperature is relatively low and the temperature rises.you very quickly. Superconducting heat pipes have strong low temperature resistance and do not freeze in ultra-low temperature environments. The inner tank of the pressure water tank is high-frequency welded and can be directly connected to the tap water system and work automatically. There is no shortage of vacuum tubes inside the pressurized solar water heater. Water greatly improves the thermal efficiency of the product, and the vacuum tube will not freeze or crack in cold weather. Even if only one pipe of the solar pressurized water heater breaks, the water heater can still work normally and it works fully automatically under pressure, which is very convenient. Disadvantages: The pressure water heater has a large surface area when installed and has a certain insulating effect on the floor. The hot water pipe of the pressure water heater is very long, which wastes belittle water each time you use it. The water heater heats the water when the sun shines all day. Hot water cannot be guaranteed at all times and comfort in this area is relatively poor. The lighting panel of the pressurized solar water heater is installed on the roof. Its installation on the roof will affect the overall beauty of the building, especially in high-end residential areas, which will damage the roof waterproofing layer over time.
First of all, when choosing a solar water heater, you should choose a pressurized water heater. Because the pressurized water outlet is stable, it will not become hot or cold. Secondly, it is recommended to choose a hot plate water heater based on the pressure type. Since the heat collector plate water heater is split type, the pressure water tank can be placed inside. It is not necessary to install it on theroof as a whole like a vacuum tube water heater, which not only solves the problem of roof pressure, but also ensures the problem of water tank insulation. Third, the pressurized water tank of the selected solar water heater must have an enamel inner tank. The enamel inner tank has good anti-corrosion effect, strong pressure and long service life. As long as it meets the above three points, it is basically a high thermal efficiency solar water heater. Of course, based on this, try to use imported heat collecting plates and anti-freeze media. Although its price is a little higher, it has high thermal efficiency and a long lifespan. Many foreign brands of domestic solar water heaters are counterfeit. They are purchased from domestic parts and assembled in the name of import.Sale. Most productsGenuine imported products come with English installation instructions, and each interface of the machine has English labels, which can be distinguished with a little attention. So there is no need to pay too much attention to the brand. Of course, it is best to have after-sales service commitments.
