One is for adding water to the solar water heater (usually on the right side) and the other is the solar hot water switch. The add water switch is only turned on when adding water (clockwise rotation is off, counterclockwise rotation is activated). Tap water is added to solar energy due to its own pressure. The hot water switch is activated when the hot water switch is turned on. hot water from solar energy is used. If it is cut off, solar heat will be lost. The water has been cut off.
1. Pay attention to the water filling time.
2. Depending on the weather conditions, determine the amount of water to ensure the appropriate water temperature during bathing.
3. Check regularly to see if the water heater's pipes, vents, and other components are working properly.
4. Rinse regularlythe suction hose in areas with severe weather conditions, heavy sandstorms or dry areas.
5． After the water heater is installed, non-professionals should not easily move, load or disassemble the entire machine to avoid damage to key components.
Solar water heater - how to repair water leaks at the top joint of the pipe
Solar water heaters are installed on roofs homes in many places, so when the weather permits, you don't need to heat the water, just turn on the water heater and use it, which is energy-saving and eco-friendly. There is a water tank in the solar system which contains tap water. It will not leak under normal circumstances. If it leaks, you must find the leak point in time and pay attention to repair it.
Common causes of hp leaksolar water heater and maintenance faults 1: Water tank overflowCause: The solenoid valve is defective and cannot be closed. The hot and cold water pipes are connected in series, the cold water pressure is high; , and the hot water pipe enters the water tank, causing overflow: the sensor fails, only the low water level can be displayed, causing the illusion of always low water level alight.
Maintenance method: replace the solenoid valve; check whether the valves of the double faucet, electric water heater, gas water heater, etc. are working properly. of the user are closed; replace the sensor.
Fault 2: Water heater leaksReasons: The water tank liner is corroded and aged; the vacuum tube is broken; the sealing ring at the connection between the vacuum tube and the water tank is aged; the inlet and outlet water pipes are aged, causing ddisconnection or breakage.
Methods: Replace the water tank; replace vacuum tube; replace the seal ring; reconnect the water inlet and outlet pipes or replace them with new ones.
Fault 3: The water pipe is leaking.Reason: If the water pipes or sewer pipes are leaking, it is because the PPR water pipes or aluminum-plastic pipes have aged after being exposed to wind and sun for many years.
Method: Replace solar hot water pipes. A leaking valve is a valve failure. In this case, a new solar valve or solenoid valve must be replaced.
Can a leaking solar water heater be repaired?It can be repaired simply by replacing the corresponding parts. Leaks in the insulation barrel of solar water heaters are relatively rare. If after inspection you find that the water tank is indeed leaking, you mustz consider replacing it with solar energy. The quality and service life of the water tank directly causes the rust and leakage of the water tank. But generally speaking, as long as it is a branded water heater, such problems will not occur.
Is the water from the solar water heater safe to drink?It is not recommended to drink it.
1. Although the water entering the water heater is clean tap water, the water used to make the water heater pipes metals often contains excessive amounts of harmful poisons , such as lead, cadmium, manganese, arsenic, etc. Over time, these harmful substances become extremely harmful to human health.
2. When tap water enters the water tank, due to the secondary pollution of the pipe network, the chlorine in the water will increase the amount of trihalomethanes that produce substances carcinogenic.
3. The temperature of water heated by solar water heaters is generally between 40 degrees and 70 degrees, which is suitable for large-scale breeding of germs and viruses.
4. Water in solar energy is often stored overnight. Due to long-term retention and the influence of temperature, the disinfection residual chlorine in the water will gradually decrease or even disappear, thereby promoting the growth of microorganisms and bacteria in the tanks and pipelines. water storage.
1. Common water leak problems:
1. Water leak at the exhaust tee
2. and water tanks Water leaks at the interface
3. Water leaks from the shower
4. Water leaks from the connection between the vacuum collection tube and the water tank
< p>5. Vacuum collector tube is damaged and leaking6. Water tank leaks after solder joint cracksure
Second solution:
1. connection between the water pipe and the joint, it depends on the type of pipe used, hot melt In the case of pipes, the connection is not good enough when hot melting, causing water leakage in the case aluminum-plastic pipes, the screws are not tightened or the sealing rings are damaged. ?
2. The connection between the joint and the water tank pipe is often caused by the raw material tape not being properly wrapped, causing water leakage. ?
3. The connection between the water tank pipe and the water tank. There are two commonly used connection methods: solder type and silicone gasket type. If it is welded, the water tank will need to be replaced. If the warranty period has expired, you will need to find an argon arc welder to remove the insulating layer and weld it. If it is a silicone type of gasket, replacesimply the sealing ring. If there is no replacement in stock, you can replace the exhaust port seal ring on the top and use it.
Detailed information
Working principle
Sunlight passes through the first glass layer of the heat absorber tube and shines on the second. Glass layer. The black heat-absorbing layer absorbs heat from solar energy. Since the two layers of glass are vacuum insulated, the heat transfer will be greatly reduced (radiation heat transfer still exists, but there is no thermal conduction or thermal convection.), which is extremely Some of the heat can only be transferred to the water in the glass tube, heating the water in the glass tube. The heated water will gently move upward along the heating surface of the glass tube into the insulated water storage bucket. The relatively low temperature water in the bucket will be backlit along the glass tube. The surface enters the glass tube for replenishment, so that the water in the insulated water storage barrel is continuously heated, thereby achieving the hot water goal.
