Water heater.
Depending on the specific situation, if your solar water heater can meet your needs, there is no need to purchase a new water heater.
If your solar water heater is not powerful enough or cannot meet your needs, then you will need to purchase a new water heater.
Are solar water heaters suitable for commercial building users? For what?
Friends who visited rural areas may have discovered a very common phenomenon, that is, almost every household has a rooftop solar water heater, but It's rare in town, even though it was said you couldn't 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.
In fact, solar energy can directly use energyfrom the sun to heat the water in the water tank, and 95% of home solar water heaters are vacuum tube home solar water heaters, which mainly use 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. , one household at a time. Installation, this type of operating modeement 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 exterior 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. 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 teeth, but it is very difficult to take a shower. Mays it's different in rural areas. Once winter arrives, many people do not have heating or air conditioning at home, so they do not take a bath at home, but go to a public bathhouse. Additionally, public baths in rural areas are very busy. cheap. If you have a swim ticket, basically two. You can wash it once for only 1 yuan, while in the city it costs less than ten yuan and more than 30 or 50 yuan. 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 homeowners with a small number of people at home.
The other is a gas water heater. Gas water heaters mainly use natural gas. It converts energy into hot water and can be heated at any time. It is very convenient to use and has become very popular among homeowners in recent years. 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.

Should I still install a gas water heater if I already have a solar water heater?
Most of the newly built high-rise commercial buildingspurchased are now equipped with solar water heaters installed by the developers upon delivery. However, I found that some users directly took it apart when decorating. Waste of electricity. Although it is solar energy, when the sun is not good, you still need to use electric energy. This solar electric heating function is not as good as the heating effect of a separate electric water heater. The high rise house I bought doesn't have a lot of OK sun, so I might as well install a separate electric water heater.
Solar energy is green and environmentally friendly. The bottom line is that we don't need to spend a penny when building the house, which can be called original supporting equipment. So why do it. some owners still have to pay for this? Has it been dismantled? My house is also equipped withthis solar water heater. Let's first see what it is. High-Rise Solar Water Heaters High-rise solar water heaters, as the name suggests, are solar water heaters installed in high-rise residential buildings, also known as wall-mounted solar water heaters. Most are split type, consisting of a flat solar collector and a water storage tank. The collector and the water storage tank are completely separated. The sensor is installed outside the balcony, on the south side of the house, and the water storage tank. is installed indoors, usually on the balcony. They are connected by two tubes.
The collector part is designed to be separated from the water storage tank. The collector does not need to store water and is much lighter. This not only solves the problem of users of high-rise residences who cannot do this. install water heating systemssolar, but also makes full use of the outdoor space and achieves the perfect combination of solar energy and architecture. This type of solar water heater has electric heating function when the temperature is not enough in rainy weather, electric heating or heat preservation can be used to meet the hot water demand of the user for 24 hours. Energy saving, solar energy is inexhaustible, and its circulation also relies on physical circulation, even in winter, this energy saving is undoubtedly due to the independent adjustment of the water storage tank, which can completely increase electrical energy. heating function, so that in continuous rain, rainy and snowy weather in winter, it is equivalent to installing an electric water heater. You don't have to worry about using hot water 24 hours a day.
Disadvantages of using hot waterhigh-rise solar water heaters. Now that I have learned so much about solar energy, I still feel like this thing is very good, but why should we take it apart? After understanding it, I got the following answer. Although this type of solar power is split design, due to its physical circulation characteristics, the water storage tank should be installed close to the collector and higher than the collector, so that the storage tank water heater is usually installed on the balcony wall. There is usually a distance between the balcony and the bathroom and kitchen. During normal use, the cold water in this section must be drained before hot water can be available, which is equivalent to wasting some of the water. Takes up space. For this type of solar water storage, if you want to have enough hot water, the water storage tank must be large. ByTherefore, a relatively large water storage tank will occupy the already small space of the balcony, which is why users are disgusted.
Gas water heaters are the most dangerous and expensive water heaters to operate. Solar water heaters generally have electric auxiliary heating. When there is no sun, it is a good electric water heater in itself. Why install a gas water heater? Even if you have a large family and are worried about the lack of hot water from the solar water heater, do not install a gas water heater. Simply install a tankless water heater. It is best to use it in series with the solar water heater. the water temperature of the solar water heater is sufficient, turn off the electric water heater; When the water temperature of the solar water heater is not enough, turn on the instant electric water heater to warm it up. This method is good, buthe pipeline is a bit complicated and not all installers may know this.
