Selection of solar water heaters

1. First of all, pay attention to the appearance. Observe whether the appearance is made of fine materials, whether the production process is exquisite, whether the overall

is beautiful and generous, the outline is smooth, the water tank shell is smooth and bright, the bracket is balanced and without distortion,

whether the vacuum tube color is uniform and without cracks, and the end cover is flat and without burrs.

2. Secondly, pay attention to the performance of the collector tube. The surface of a high-quality vacuum collector tube should be smooth and flawless, and the coating should be pure black or blue. Check whether the selection of materials and structural installation of the reflector are reasonable, so that the corrosion resistance will be stronger. The surface of a good reflector has a lasting luster and beautiful patterns.

Some products use imported stainless steel plate mirrors, such as reflectors with assembly line curves, and the concentration rate will also be relatively improved.

3. Thermal insulation performance of the water tank. Whether the water tank and the shell end cover form a whole without gaps,

this will have strong corrosion resistance and a longer life.

4.The tightness of the water tank and the firmness of the bracket. The inner tank of the solar water heater is made of stainless steel. Observe carefully whether the welding joint is basically the same as the parent material; secondly, whether the bracket is firm.

5. Finally, when purchasing, you should choose a brand with a good reputation. At the same time, you should also pay attention to whether there are complete instructions, certificates, warranty sheets, trademarks, etc. Don't focus on price and ignore quality (including product quality and service quality). Only in this way can you buy a satisfactory solar water heater.
