Solar water heater problem, help!!

Buying a 200-liter solar water heater can save about three degrees of electricity a day, and the daylight hours in winter are much shorter than in summer, so the energy generated is also different. Now the solar water heater has become very mature, just like the computer accessories in Guangdong. It is better for you to buy more or buy a well-known one, because there are still substandard products mixed in it, you are not an expert can not distinguish, in order to avoid unnecessary losses to buy a more well-known one, spend more money to buy rest assured.

Among the well-known products, there are also expensive series products and cheap series products. In fact, there is not much difference between expensive and cheap ones in terms of service life and thermal efficiency, you can just buy a cheap series. It also saves a lot of money.

The average family can hold 40 liters per person, and a hotel like yours needs about 60 to 120 liters per person. However, you can also count it as forty liters, because the water temperature is very high in spring, summer and autumn. To a lot of cold water so that the tank is equal to become larger.

General solar water heaters do not require electricity, but it is recommended to buy a solar water heater with electricity-assisted heating according to the local time of day, if there is fog all year round, or there is little sun.

A person generally needs 30 liters of water to take a bath, and you can calculate how many liters of solar energy you need according to the occupancy rate of your store, and there are generally two capacities marked on the solar energy, one is the capacity of the water tank, and the other is the total capacity, the water we use is only the hot water in the tank, so you need to see what the tank capacity is in it.

Or you can find a local solar dealer to install a collector project.

1 If your solar energy is used for hotel bathing, then you must install solar energy with electric auxiliary heating. As for how much electricity can be saved, as long as the solar energy with good effect is sunny and sunny, it does not use electricity at all, and only uses electricity when it rains on a cloudy day, and it is possible to start electric heating if the temperature is too low in winter.

2. About 50-80 liters of water for each person shower (about 50 degrees of water), solar water is used less when the temperature is high, and more when it is low, according to the water consumption of each person, you see how many people you use. In this way, the total water consumption comes out. You can see how much solar energy is used.

How many rooms are 20 rooms? A person would use about 50 liters of water if it was normal. Seriously, it is 50 liters of water, which refers to the water for bathing, not the high-temperature water in solar energy, which should be considered.

Also consider the water temperature of the solar energy, and the cold water temperature. It is recommended not to use tap water directly for cold water, as the temperature is low, which will affect the temperature of the water. And spend money to buy transparent vats or water storage irrigation, the water temperature inside is not low, can improve the use of solar energy, although it is a bit dirty, save money.

Secondly, it is best to have a large amount of solar water storage, sometimes the water storage temperature reaches more than 95 degrees, and the water of the solar heating tube is boiled, which is equivalent to wasting energy, which is equal to the water on the stove being boiled, but because the kettle is too small, the water is not enough to use. So to "big kettle". Buying something, I think you get what you pay for.

Among them, the brand is also very important, and the big brand is still good. It's a lot, it's messy, don't mind, it's my experience and feelings.

According to the calculation of 15---20 people: about 500 liters, and it is almost the same to install two sets of 30 58*180 pieces. **Probably 7,000---10,000 yuan.

The service life of solar energy is 3-5 years, and it is estimated that it is difficult to supply it when there are many users, you can go to the market to find out in detail.

I just installed Linuoret's, which is very good for home use, with a net capacity of 158 liters, which can purify water, install an anti-freeze line, and have water temperature and water level displays. And it's an aluminum alloy bracket that never rusts. It's just **expensive. This is the only Sino-foreign joint venture solar energy.

If you open a store, you should pay attention to the cost, you can install a second-tier brand, hundreds of liters of large capacity, you can save a lot of money. One can fit several rooms.

Generally, when there is sun, there is no electricity, so you can save as much electricity as you can when there is sun on how many days, and you can save about 10 kilowatt-hours of electricity a day. The main thing to buy solar energy is its quality and service, and now the quality is almost the same, and the most important thing is to look at the service.

<> Solar water heater controller failure: 1. The leakage is displayed, which means that there is leakage in the line or electric heating; It is recommended to check the electric plus circuit or replace the electric heating; 2. "Temperature level display" - water level display 20%, 100% bright; It may be that the direction of the four-core plug-in of the sensor is wrong or the contact is poor, the signal line is broken, and the sensor is damaged; It is advisable to check the wiring sequence.

This answer is applicable to most brands of water heaters such as Songshen Xiaonaxia, Wanhe, Gree and so on.

Generally, 58*1800 pipes 3-4 pipes per person in summer 5-7 pipes in winter So 4-5 people take a bath every day 24 pipes are enough Electric heaters are generally 1500w recommended.

The solar water tank is the key, and the main tank is in the inner tank, the inner tank is mainly divided into stainless steel and enamel liners, and the stainless steel material process is simple, that is, the purchase of stainless steel iron sheet can be welded, which is why there are so many solar manufacturers and brands now, it is because it is too simple!! The high-quality, high-end solar products, such as split solar energy, balcony wall-mounted solar energy, are made of enamel liners, and the characteristics of enamel liners mainly include:

1. Better thermal insulation, real thermal insulation wall (rather than the thermal insulation wall of conceptual hype), 2. No corrosion, no leakage (metal and water contact at 60 ° will oxidize, corrosion, enamel liner is made of silicide glaze layer baked at 900 degrees, water and metal do not contact, so it will never rust);

3. No scale, clean water quality, no secondary pollution.

Because the production process of enamel liner is complex, the technical requirements are high, and the production cost is high, so the enamel liner is mainly used in high-end and high-end products.

With the gradual maturity of the solar energy market, solar energy upgrade products--- enamel liner solar energy is becoming popular.

At present, the market is mainly Jiangsu Guangguang Group produced by the light blue diamond solar energy for the enamel liner products, the liner is the light group electric water heater liner directly used in solar products, its blue diamond enamel liner is a high-tech product followed by many high-end solar products. At present, the enamel liner produced by Ray Technology Company has reached the national fatigue test standard of 160,000 times for electric water heaters, the 250,000 times fatigue test standard for Australia, and the standards of Europe and the United States, becoming the only enterprise in the solar energy industry to meet these standards.

According to the amount of water consumption, each person can be calculated according to 50-80 liters, the power of the auxiliary power is generally 1500 watts, and the power consumption for one hour of energized work is the degree. It is recommended that when the weather is bad, do not fill the water tank, just add half, so that the water temperature rises quickly through the auxiliary electricity, and the water temperature rises slowly if the water is filled. Now the quality of solar water heaters at the same price is similar, the key is to ask clearly, all kinds of accessories are best produced by the original factory, the quality is better, otherwise you will use very poor quality of the original accessories, such as water pipes, water valves, joints, insulation sleeves, electric heaters, etc.

The fitting should be copper, and the thicker the insulation sleeve, the better.

1. The purchase of solar water heaters should consider the local climate, the demand for hot water and the population to decide the size of solar energy.

2. At present, the vast majority of solar southern machines are equipped with electric heating auxiliaries, with power of 1000W, 1500W, 2400W and 3000W; Taking Huangming Solar as an example, the average temperature can rise by 6 degrees per hour, and if the electric heating power is 1500W, the power consumption will be 1500W.

3. Solar energy can also be upgraded, and the technical content is also very high. Xianghuangming Solar's Winter Crown series water heater can be upgraded; When the demand for hot water increases, adding an outdoor unit will have limited space and the same capacity as the previous model will have to be purchased, but the capacity will be too large. However, it is only necessary to add an indoor unit, and it can be heated immediately - upgraded to a 3G household hot water center.

4. If you live in the south, it is recommended to choose Huangming Shuangteng water heater; If you live in the north, you can buy a Huangming winter crown water heater.

The purchase of solar energy is mainly based on your actual water needs, your permanent population of 4-5 people, shower or bath, do you still need hot water in the kitchen, if the regular population is just bathing, other water is generally calculated according to 40 liters, if there is a bath, the water consumption is relatively large in comparison, choose assured solar energy, including pre-sale sale and after-sale every part is very important, now most of the solar energy is equipped with auxiliary heating, electric heating only plays an auxiliary role, The power is generally 1500w 2400w 3000w models are not the same, the power is also different, you can consult more, learn more, I wish you to buy a satisfactory product.

About 160L, the electric auxiliary heating power is generally 1500W, and it is generally not used; The one I use at home is Linuoret's, and the quality is stable.

16 58 tubes of Huangming, Linuoruite, and Sun Rain can be used, and they all have auxiliary heating, and the quality of the inner tube is to see if the surface of the inner tube is smooth and has not fallen off.

First of all, there must be an exhaust vent, and if there is more water, it will flow out. Unless it is installed with a pressure water heater with no exhaust holes, there is no need to worry about water flowing out.

If you use solar energy is a single pipe for water supply. The connection at the bottom should be a mixing valve. If there is hot water flowing out, there will be no cold water flowing in, and there is no need to worry about cold water flowing into the tank.

If there are two pipes, one on the water and one on the water, then the cold water you are using will have nothing to do with the water heater. You can use it to your heart's content.

So you use it as much as possible and don't need to worry about the tank overflowing.

Normally, if there is water overflowing from the tank, it means that the plumber made the wrong waterway.

Can you send a **, I will look at your valve position and situation, you should have more than one valve.

Is there a display board that shows the water temperature and water level in the room, if it is a manual water supply, there should be an overflow pipe at the bottom of the water tank, and the water will flow after it is full.
