The reasons why hot water cannot be released:
1. For the top water method, the tap water pressure is not enough and hot water cannot be released. Sometimes the hot water pressure is higher than the tap water pressure and the hot water enters the cold water line.
2. The exhaust pipe of the open water tank is blocked and hot water cannot be discharged.
3. The hot water valve cannot be opened or is blocked by foreign objects.
The solution is:
1. If the hot water pressure is not enough, please buy a hot water booster pump from Will or other brands if the hot water pressure is higher than; tap water pressure, that is, if the cold water pressure is reduced, please buy a cold water booster pump from Will or other brands.
2. If the exhaust pipe is blockedproblem or if the hot water valve is blocked by a foreign object, you should ask a professional plumber or professional technician from the solar water heater manufacturer to remove it. it's yourself.
Detailed information:
Solar energy generally refers to the radiant energy of sunlight. Solar energy is a renewable energy source in a broad sense, solar energy is the source of many energies on earth, such as. such as wind energy, tidal energy, water potential energy, etc. The basic methods of using solar energy can be divided into four categories: thermal light use, electric light use, chemical light use, and biological light use .
Among the four types of methods of useation of solar energy, light-heat conversion technology is the most mature, has the most products, and is relatively inexpensive.
Such as: solar water heaters, water boilers, dryers, solar cookers, solar greenhouses, solar rooms, solar desalination devices and solar heating and cooling devices, etc. Solar thermal power generation has a higher solar energy conversion efficiency than photovoltaic power generation, but its application is not yet common. In photothermal conversion, the application of solar water heaters has the widest application range, the most mature technology and the best economy.
1. Photothermal use: It collects energy from solar radiation and converts it into thermal energy by interacting with matter for use. Currently, the most commonly used solar energy collection devicesUsed include flat plate collectors, vacuum tube collectors and focused collectors. Solar Power Generation: Large-scale use of solar power in the future will be used to generate electricity. There are two main ways to use solar energy to generate electricity:
(1) Light-heat-electricity conversion. In other words, the thermal energy generated by solar radiation is used to produce electricity. Generally, a solar collector is used to convert the absorbed thermal energy into steam as the working fluid, and then the steam drives a turbine to drive a generator to produce electricity. The first process is light-to-heat conversion, and the second process is heat-to-electricity conversion.
(2) Conversion of light into electricity. Its basic principle is to use the photovoltaic effect to directly convert energye of solar radiation into electrical energy. Its basic device is a solar cell.
2. Photochemical use: This is a photochemical conversion that uses energy from solar radiation to directly decompose water to produce hydrogen.Path.
3. Photobiological use: The process of converting solar energy into biomass through plant photosynthesis. Mainly include fast-growing plants (such as firewood forests), oilseed crops and giant algae.
Working principle
Sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the second glass layer, absorbing the heat from solar energy. The glass layers are vacuum insulated and the heat transfer will be greatly reduced (radiant heat transfer still exists, but there is nothermal conduction or thermal convection).
Most of the heat can only be transferred to the water in the glass tube, causing the water in the glass tube to warm up. The heated water will move gently upward along the heating surface of the glass tube and. enter the insulated water storage bucket. The temperature in the bucket will be relatively high. The bottom water enters the glass tube along the backlight surface of the glass tube for replenishment. This continuous circulation makes the water in the insulated water storage barrel heated continuously. thus achieving the purpose of hot water.
Daily maintenance
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When you use it for the first time, you can turn on the faucet. to remove debris first.
2. Water stored in the heaterSolar water should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase the flow ofwater. smooth exit.
6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can also use a hair dryer to blow on the water line, or wrap a towel around the water line and then slowly pour warm water over it. Do not cook it on fire, hit the water pipe, or scald it with boiling water, because. this will cause the pipe to burst. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
7. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. Users can also do some disinfection work themselves, such as purchasing disinfectants containingchlorine and add them. At the water. Pour it into your mouth, soak it for a while, and then release it, which can achieve a certain disinfection and sterilization effect.
8. Solar water heaters need to be cleaned inside the vacuum tube every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect.
9. If the solar water heater is equipped with special instruments, please pay attention to lightning protection and electrical protection. Do not take a shower and unplug the electric heater during lightning.

Why solar energy can't produce hot water:
strong>
1. This may be due to damage to the float valve. Or it may be due to it not being closed tightly, because in this case the cold water will conconstantly renewed, which will prevent the water temperature from increasing. So no hot water comes out.
2. It can also be caused by water leaking into the valves or seals, etc. You should ask professional repair personnel to handle it.
3. For solar cells with multiple water outlets, this may be caused by cascading water. It can be replaced with an independent valve so that it does not affect the use.
Precautions for using solar water heaters:
When using solar water heaters, the first thing you should pay attention to is the adjustment problem of temperature, and when using it in winter. , the solar water heater pipes are very sensitive. Freezing and blockage are likely to occur, and once the water pipe is blocked, it will affect the normal use of the water heater.
In order to avoid this kind of situation, it is preferablethe to insulate the pipes of the solar water heater as well as the water pipes of your house during their use in winter. For example, for families in the North, when using solar water heaters, they will basically choose to wrap several layers of quilts over the pipes.
