Hello, it is recommended to look at the vacuum tube type, bracket thickness, water tank material and strength of the buyer! At present, under the condition of ensuring quality, the general market price outside a single warehouse is between 110-150 yuan/tube. Because the dealers are different, the prices are also different. It is recommended to refer to the following. several companies.
Recommended "Dr. Sun" solar energy, three warehouse models (no need for water level probes and solenoid valves), heating and hot water utilization rates are fast in rainy weather, and the after-sales service rate is also greatly reduced, saving time. It also saves electricity. This model only takes 20-30 minutes to heat without sunlight, while the single-tank one takes 2-3 hours.
You speak! about 18 tubes! He should do58*1800. If it is this model, the seller's price should not exceed 1,600 yuan including installation and material costs
But I advise you that the registered trademark is similar to. “Beida.” 99% of manufacturers like "Tsinghua" only go through colleges and universities, that is, the brands are not registered at all. Whether the quality is good or not depends on your luck. The brand "Tsinghua Sunshine" is a registered trademark, but during this year's solar water heater industry summit, it is very likely that the brand "Tsinghua Sunshine" will no longer be used in the second half of the year
< p>Our industry has relatively low production and technical thresholds and poor monitoring. In recent years, the phenomenon of competition with Beijing brands and universities has emerged. nothing to do with universities. In recent years, there has been a tendency to compete with device brandss, such as “Haier Sunshine” and “Haier Sunshine” and “Meide Sunshine”. other large companies. They can be produced in their own backyard by the couple, the seventh aunt and the eighth aunt. Those carrying the banners of "Hong Kong Four Seasons Muge" and "International Emperor Ming" are all fake. >As for the website, there is no authoritative one. You can only check brands one by one.
< p>The key elements of a solar water heater are the insulation of the water tank, the material. and the thickness of the cladding steel, as well as the quality of the vacuum tube. However, even those in our industry cannot use these items without damaging the product or using precision instruments but once the quality is substandard and damaged. , it cannot be repaired. For example, if the inner tank of the water tank is leaking, you need to find the leak point, destroy it completely.nt the end cover to one end of the water tank, dig out the insulation layer and weld it with argon. arc welding. Re-foam the polyurethane and secure it with a new end cap. The cost is about the same as buying a new water tank, and the welding joint will not last long.So, I. I advise you to pay more. Spend a little money and buy a brand.
I recommend a few brands, ranging from good to slightly not so good, but they are all useful, Yicanon, Sijimuge, Sunyu, Sangle, Sangxia, Meiling, Royalstar, etc., and of course there are which I don't remember. As for which model you want, the prices of these brands should be above 2800 yuan.
