Abstract: how can we fix the solar water heater after the strike? Today, the solar water heater on the roof is a new bright spot for modern homes and, unlike traditional solar energy, the solar water heater is placed on the roof because of chronic weather failures. The following is a compilation of some of the most common solar water heater failures and solutions to them。
Solar water heater maintenance methods
Common failures of solar water heaters and maintenance methods

B. Water pipelines are cut off。
Exclusion methods:
Replacement of vacuum tubes;
B. Connecting up and down the pipe or replacing fittings。
Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
4. What are the reasons for the water in the solar water heater? What should be done?
Reason:
A. Water heaters are covered with short daylight periods;
B. Low closure of upper and lower water valves;

C. Cleaning of vacuum tubes;
D. Cleaning of the vacuum tube and the surface of the raster;
E. Replacement of large-capacity water heaters or electrical heating systems;
F. Analysis of weather conditions and attention to water on water heaters volume
Note: in the event that a user encounters the above, do not dismantle itself and should contact the local service provider to exclude it。
Five. There's water in the hot tub
Method of exclusion: checking and wringing the back of the temperature-control valves on the collector board and the electrostatic heater when no solar light or electric heating is activated, whether the pressure-barrel core is resilient with the parent finger, or, if elastic, pressing the needle in the middle of the core of the valve in the middle of the flat opening. If both temperature-controlled valves are closed, the water return phenomenon should be checked; when the hot water valve is closed, the hot water pipeline (under the one-way valve) is opened to see if cold water flows, and if so, the water should be checked and discharged back to the water。
6. No water release from the hot water pipe (no water in the heatbox) and no output from the internal fluid control box (no red light)
Method of exclusion: check if the sub-water tank has cold water, and if so, whether the empty and leaking electrical switches in the control box have jumped, check if the liquid-level control power source has indicated that the green light is on, and check if the switch template has 220 v from the left number of first and second connections, if not from the sequence; if the liquid-level controller green light is on and the red light is not on, the second and third high-altitude water level lines on the right should be removed first, and if no output or no output of the red-level light is on, the liquid-level controller should be inspected or replaced; if the output is available, check the presence of rust short roads or dirt between the two lines of the water level probe, and clean up or replace the water level line and the probe。
Exclusion methods:
(1) checks the contact point for good contact on the wires and panels of the contacts。
(2) disconnect the power supply, replace the supertemperature protection fuses 2 and 4 with a steering line, connect to the power source and the contact inhaler, and check whether the supertemperature protection is automatically disconnected or burned due to cold water shortage; (a) disconnecting the power source to replace the hypertemperature protection component; if the contact pointer does not inhale, the power source is disconnected to remove the contact pointer's lead, and the circle is checked with a mass-use watch, if the loop is short or broken, replace the contact pointer, and the failure is resolved。
7. The contact is inhaled when the water level of the tank is above the high water level probe; when the water level of the tank is below the low water level probe, the contact point is not inhaled
Exclusion methods:
(1) check that the surface is connected。
(2) take down high, low-water-level leads and connections. Take step two。
(3) prepare three guide lines, one for the ground, one for the low water level and one for the high water level。
(4) short-link the surface line and the low-water-level lead line, at which point the liquid-level controller should have an output or, in the absence of an output, the liquid-level controller would have malfunctioned or, if there was an output, proceed。
(5) shorten the high-water and low-water lines and the ground line, at which point the liquid-level controller should have no output and, if there is an output, the liquid-level controller would have malfunctioned. If no output is available, proceed with the next step。
(6) high, low-water-level lead lines shall be attached to each other at this time and the high-water-level lead lines shall be severed. The water level line shall be replaced if the liquid level controller does not output failure。
8. Inhalation of contacts, leaking switches in position to join, but slow heating
Method of exclusion: the heat pipe shall be inspected for damage and, in the absence of a table of mass use, the electrocution or hearing examination may be performed separately. (if the heating tube leaks an electric switch, the heater should be replaced)
Nine!
Reasons and exclusion methods: long periods of sunlight or inadequate sunlight, if any, then check whether the local water pressure is due to the absence of cold water during the daytime and the use of cold water during the night, or the lack of air in the collector board, which prevents access to the solar heating panel, so that no hot water is produced during the day, so that the electric heater is automatically activated during the night, resulting in large amounts of electro-heating and no solar energy, and the failure should be resolved by contacting the factory's professional technicians。
Knowledge on the use of automatic water-upper solar water heaters
1. More than water
Reason:
A. Excessive length of single tube into and out of the water valve chain;
B. Poor quality of water, which makes it easy to generate water or impurities to accumulate on the core of the valve, so that the valve is not closed;
C. Damage to the valve itself。
Exclusion methods:
A. Interrupting redundant chains by standard length;
B. Stop valves with filters;
C. Replacement valves. Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
2. The sound of solar energy in the water
Reason:
When the water tank is close to full, if the water is overpressed and floats up or down, there will be a sudden opening of the valve. When the flounder valves are suddenly closed, a space vacuum is created by the sudden lifting of the valve core, which cannot be replenished by running water, which is the best medium for sound transmission, resulting in considerable vibration。
Exclusion methods:
Add limit flow valves. Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
Auxiliary electric heating
No heat
Reason:
A. Actual water temperatures are higher than the temperature of a thermostat; b, an overheating shield jumper due to mishandling; c, thermostats; d, power lines are damaged。
Exclusion methods:
A, add a little cold water to reduce the water temperature in the tank to start electric heating;
B. Manually press the small superheating protection button after failure;
C. Replacement of thermostats;
D. Measure whether the power lines have burned down, especially at the various interfaces of the power lines, using a universal meter and then exclude them. Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
B. Fault protection plug failure to deliver electricity
Reason:
There's a leak in the electro-heating system
Exclusion methods:
Each component of the electro-heating system is measured and excluded on a single scale. Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
Three, heated
Reason:
Burning the heat relay
Exclusion methods:
Replacement of thermostats. Note: in the event of a situation, please do not dismantle yourself and should contact the local service provider for exclusion。
