How can the whole tank of water in the solar water heater be completely empty in 1 night 5

Leaks, and I've had this happen, and the valves didn't close tightly, and after a tick, the water from the solar energy leaked out overnight.

Looking at the valve pipes, a tank of water should be easy to find the leakage.

There are several possibilities:1The valve is leaking. 2.Leaking pipes. 3.The glass collector tube is broken.

Manufacturers say that the service life of solar water heaters is about 15 years, and consumers should have a clear understanding of this. Reasons for the "short life" of solar water heaters First, vacuum tubes. The vacuum tube is the core component of the solar water heater and the "heart" of the solar water heater.

Its quality directly determines the performance of the whole water heater. The performance of vacuum tubes is affected by coating technology and cleaning, coating, vacuuming, sealing and other processes. However, some ultra-low-cost solar water heaters use vacuum tubes with the following drawbacks:

The vacuum level is low, only 1 100 for high-quality products;A large amount of impurities and water vapor remain in the pipe, which will turn into gas when it encounters high temperature, and the vacuum degree will be reduced; The stability of the film layer is poor in the low vacuum state, and the film will age and fall off within two or three years, resulting in a sharp decay of the heat collection performance and the inability to absorb enough heat. Second, the insulation layer. The hot water produced by the solar water heater during the day is stored in the water storage tank, and if the thermal insulation performance of the insulation layer is not good, it cannot be used overnight or on rainy days, or it is not easy to use.

The main reason for the poor thermal insulation performance of solar water heaters lies in the thermal insulation layer of the water heater, which determines the temperature of the hot water and the amount of hot water. A good insulation layer is made of imported raw materials, such as polyurethane, with low thermal conductivity and high temperature resistance; The insulation process adopts automatic constant temperature and high pressure quantitative foaming, and is cured at high temperature, with high thermal insulation performance and stable and durable. However, some inferior materials have high thermal conductivity and uneven foaming, and the temperature can drop by more than ten degrees overnight, and there is no hot water on rainy days.

There are also black-hearted enterprises, in order to reduce costs, even use self-made benzene boards, after a few months the insulation effect plummets, and after one or two years, it is basically not insulated. 3. Liner. At present, most solar water heater manufacturers say that the tank liner is stainless steel.

The same stainless steel, but the chromium and nickel in stainless steel are very different. A good solar water heater uses a stainless steel liner with high chromium and high nickel to ensure that the liner is durable and durable, and has strong corrosion resistance; Inferior liners are mostly made of low-grade stainless steel, which basically does not contain nickel, has poor corrosion resistance and short service life. 4. Installation and service.

Solar water heaters have very high requirements for installation, and professional installation is the foundation and guarantee for their easy use in winter. Some miscellaneous enterprises often recruit migrant workers to form a "guerrilla team", and they have not undergone formal training to take up their posts in a hurry, these people do not understand the design of pipelines, the fixation of the main body of the water heater and other professional knowledge, but also do not understand the maintenance of the product in the later stage, causing problems abound, directly affecting the "standard life" of solar water heaters. For example, the accessories used to fix the installation bracket of the water heater, the big brands mostly use steel wire strips, which are strong and corrosion-resistant, but some small manufacturers use iron wires to fix, resulting in some areas as soon as they encounter heavy rain, hail and other bad weather, many solar water heaters fall to the ground.

Check the valves, pipes and vacuum collector pipes, and there should be a big puddle of water that leaks overnight, and you can see it when you go up and look at it.

Leak, check in ** leakage, first fill the water and then see if the faucet for hot water is closed tightly, all closed tightly to the top of the heavy solar energy down to see if there is a leak in the interface

The reasons why the solar water heater does not produce water are as follows:

1. The water in the water tank has been emptied, and it can be used after it is full of water and heated.

2. The pipeline interface falls off or is blocked, and the pipeline is reconnected or dredged.

3. In winter, the upper and lower water pipes may freeze. The sun melts on its own about 3 hours after it comes out. In cold areas, a vent valve can also be installed.

4. The upper and lower water valves are leaking, the upper water valves are also leaking, and the water pipe has no water for a long time, resulting in water backflow, which needs to be repaired and solved.

5. The sprinkler valve or hot water nozzle is out of order, and it is not actually opened, and it needs to be repaired.

Summary. There are several possible reasons for the above situation:1

The check valve of the solenoid valve on the solar water supply valve is broken, and the hot water flows back into the tap water pipe when the water is stopped. The trap between the solar inlet pipe and the water pipe is broken, and the water in the solar case returns the same way after filling with water, so there is no water in the case. 2.

When the water is stopped, the water supply function is activated, the solenoid valve is opened, but the pipeline is empty, and the solar water flows back into the tap water pipe. When the water supply function is turned on, the pipe valve is open, and the water in the chassis will flow out if the tap water does not enter, which will also cause water loss in the chassis.

The solar water heater will be full of water for a while, and it will run out of water after a while.

What exactly is your question?

Do you want a solution or do you want to ask why?

There are several possible reasons for the above situation:1The check valve of the solenoid valve on the solar water supply valve is broken, and the hot water flows back into the tap water pipe when the water is stopped.

The trap between the solar water pipe and the water pipe is broken, and the water in the solar case returns the same way after it is filled with water, so there is no water in the case. 2.When the water is stopped, the water supply power is activated, and the solenoid valve is opened, but the pipeline is empty, and the solar water flows back into the tap water pipe.

When the water supply function is turned on, the pipe valve is open, and the water in the chassis will flow out if the tap water does not enter, which will also cause water loss in the chassis.

1. First of all, you need to determine whether you have set up the automatic water supply, if it is automatic water supply, it must display the water full state;

2. The following kinds of will cause the display to be full: water temperature and water level sensor failure; The solenoid valve is faulty, and it cannot be turned off when the water is full; The indoor water mixer is faulty, the cold water and hot water are the same, and it is in a slow water state;

3. If you do not set up the automatic water on the bucket water, but set the manual water on the water, but the water does not show that the water is full, it is caused by the failure of the water level sensing probe, just replace it, it is recommended to find a maintenance master or buyer.

How to put on water: When adding water to a solar water heater, users should first know what kind of water flow control system is installed on the solar water heater at home

1) If the overflow pipe is installed, the user can first open the stepless control valve water function or water ball valve to replenish the water to the solar water heater, if the overflow pipe installed in the room has water outflow, it proves that the water tank has been full of water, then close the stepless control valve water function or ball valve.

2) If the integrated valve is installed, the user brother or mill should open the water valve, the tap water starts to replenish the solar energy through the water supply and water pipelines, and the water is automatically closed when the water is full, and the water valve is closed when the water is used, and the water switch or mixing valve can be opened.

3) If the water supply function control system is installed, the user first clicks the water supply button of the control system, the solenoid valve is opened, and the solar energy is replenished, and when the set water level is reached, the control system stops feeding the solar energy.

Hello, I'm glad to answer for you: Huiqi may have the following situations First, the most likely reason is that the water tank of the solar water heater has too poor thermal insulation. Second, the water valve is not closed, or the Xinbi Jin meter is damaged, and it has been watering a small amount of water, and at the same time, it is also returning the base water.

This results in the water in the tank, where hot and cold water are constantly mixed. In this case, the water temperature drops rapidly due to the lack of sunlight at night. Hope it helps you and I wish you a great life
