At present, under the condition of ensuring quality, the general price of solar energy in the external market is between 120-160 yuan/tube. Because the specifications and materials are different, the prices are also different. Notice, it is recommended to buy a solar water heater. Take a closer look at the internal diversion structure of the water tank, compartment structure, water tank material and buyer strength!
Particular attention must be paid to the solidity of the buyer, as this implies after-sales service. It is recommended to refer to the following companies. At present, the maintenance rate of solar energy in a single warehouse. is still relatively high, while the maintenance rate of three-warehouse solar power is much lower! But don't forget to buy "fake three warehouses" and old three warehouses "first and second generationion”. Many of them are blocked by stainless steel plates in the water tank and are not insulated at all, while some still use an external downward bypass; and For outdated instruments, the failure rate is still very high.
1. If the water tank liner is leaking, it is usually due to aging or damage to the water tank liner. At this point, the water tank liner should be replaced with a new one. If the water tank liner leaks due to aging or damage to the sealing ring, you only need to replace the sealing ring with a new one.
2. If there is a water leak in the upper and lower water lines, it is usually due to aging or damage to the lines. At this point, the damaged pipes should be replaced with new ones. 3. If the solenoid valve or solar valve inside the heatersolar valve is damaged or aged, causing water leakage at the valve, the solenoid valve or solar valve must be replaced with a new one.
4. If the heating tube inside the solar panel is rusty, damaging the heating tube and causing water leakage in the heating position, the heating tube should be replaced with a new one. 5. If there is water leakage in the vacuum tube of the solar water heater, it is usually caused by the aging or damage of the sealing ring at this location. At this point the vacuum tube should be removed first, then the gasket. the ring must be replaced with a new one.
