First of all, it is very profitable to supply hot water to the bath industry, then we will see how much water you need to supply every day.
The current price of hot water at around 75 degrees in the market is 22 yuan per ton. If you use waste heat steam from thermal power plants to produce hot water, the cost is about 12 yuan. yuan per ton, which is a relatively good method.
It is impossible to use coal boilers to heat hot water. The government will never allow it. Don't even think about using gas boilers, oil boilers and electric boilers. the costs are staggering!
Unless you build a solar hot water plant to produce hot water, the cost per ton is very low, about 4 yuan.
If you have the capacity, build a 200 ton factory. hot water installation per day.The investment in a solar water plant is about 1.5 million.
According to the current water price, the cost can be recovered in two years. This system can be used for 15 years. and the remaining 13 years will be net profit.
There is a net profit of at least 900,000 yuan every year, which represents an income of more than 10 million yuan in 2013.
What is the use of a heater -water to air? What is the difference between it and a solar water heater?
Friends who have visited rural areas can find a very common phenomenon, that is, almost all households will have a solar water heater on the roof of each house, but this is rare in the city, and it is impossible to even see it. For what ? Is it because solar water heaters are not easy to use? Of course, this is not the case. If it wasn't easy to use, this product would probably have been off the market a long time ago.
Infact, solar energy can directly use the sun's energy to heat the water in the water tank, and 95% of home solar water heaters are vacuum tube home solar water heaters, which use mainly heat. collection tubes, water storage tanks and supports. It is composed of related parts and components. The conversion of solar energy into thermal energy mainly relies on evacuated collector tubes. water to achieve the required hot water. In this way, it is not only environmentally friendly and healthy, but also saves a lot of electricity bills at home.
Although city dwellers rarely use it, the reason why it is very popular in rural areas is also very simple: First, most cities are high-rise buildings and water heaters Evacuated tube solar panels are usually placed on the roof. , Ahousehold at a time. Installation, this type of operation mode is difficult to achieve in the city, and residential property also allows private installation of large objects on the roof, unless there is an independent outdoor balcony on the top floor. It's different in rural areas. Generally speaking, people in rural areas build houses on their own property. The place is relatively large and bright, and it is only a small building with no more than three floors, so it is very convenient to install. solar water heaters, as shown in the picture below.
The second is that if you use a solar water heater, the hot water will definitely be sufficient in summer. Even if it's cloudy or rainy, you don't have to worry about running out of hot water. water at home. But in winter, if there is not enough sunlight, hot water will not be enough. But it is still possible to wash your face and brush your faceclench your teeth, but it is very difficult to take a shower. But it's different in rural areas, once winter comes, many people don't have heat or heat in their house. There is air conditioning, so I don't take a bath at home, but I'm going to a public bath. Additionally, public baths in rural areas are very inexpensive. If you have a bath ticket, you can basically take a bath for two yuan. whereas in the city, it costs less than ten yuan, and it would cost thirty or fifty yuan more. This is therefore one of the reasons why city dwellers hesitate to use solar water heaters.
So what can we use if we don't use solar water heaters during urban decoration? There are generally two types. One is an electric water heater, which is usually converted by electric heating and then stored in hot water before it can be used. Water heater, it is generally suitable for owners with a small number of people at home.
The other is a gas water heater. The gas water heater mainly uses natural gas energy conversion to heat hot water and can be heated at any time. It is an instantaneous water heater and it is very practical. use. In recent years, it has also become very popular among homeowners. But before installing a gas water heater, it is best to first determine if gas supply is available in the community. Some communities do not provide it. When installing, be sure to install the gas water heater in a ventilated area and not in the room. bathroom.

There are heatersto domestic and commercial air-energy. Domestic air-to-energy water heaters are water heaters that provide domestic hot water. some shopping centers, hospitals, bathing centers, equipment that provides hot water in places with large amounts of hot water, such as public baths and swimming pools.
Air-to-energy water heaters
What are the differences between air-to-energy water heaters and solar water heaters:1. The main sources of heating energy are different.
Air water heaters use the energy of the air, that is, the free thermal energy present in the air, while solar water heaters use the solar energy, i.e. the energy of thermal radiation from the sun, as heating energy.
2. Different adaptability to external weather conditions.
Solar water heaters are seriously affected by weather conditions and do notcan only be used on sunny days with abundant sunlight. In case of rainy, snowy or nighttime weather, they can only rely on electric auxiliary heating (the cost). (the electric auxiliary heating is very high). In winter, intense cold can also freeze the water heater. But air-to-energy water heaters are different. They are not affected by the external environment when operating and can operate ideally in all weather conditions. Some models (such as Gemeiyue's low temperature air-energy water heaters) can also be stable in cold weather. ambient temperature of -30°C.
3. The requirements for installation locations are different.
In order to absorb sunlight, solar water heaters must be installed in a special place, usually on the exterior roof, and occupy a relatively large area. The air-energy water heater occupies a surface area rerelatively small, especially the specially “scaled down” all-in-one machine. It can be installed not only on balconies, air conditioners, bathrooms, etc., but also in the living room.
