Looking to buy to four

    North is the cold days of winter frost. After a hard day, come home if they can comfortably wash on a hot bath, could have been a very relaxing thing, but many consumers are bothered by this. Because some water heaters in winter is not easy to use one, especially .

    Solar water heaters as a green, energy-saving, environmentally friendly products are being more and more consumers. However, some solar water heaters in winter will not be able to use one, like a hot bath has become a difficult thing. \"315 day\" programs have received any listeners on this reflection. Delicate water users in our message on the microblogging program, said: his family\\ s solar water heater insulation is poor, a little heat of the night off.

    In addition, recently, Beijing, Tianjin, Changchun, Harbin and other places of consumer rights jointly launched a solar water heater usage survey also found that many solar water heater one winter strikes.

    Public Tip

    The purchase of solar to \"four to see\":

    Effect of concentrating collectors a look. Concentrating water heater capacity is a measure of the strength of an important indicator of performance strengths and weaknesses, but also affect the water heater was an important factor in the heat. Vacuum tube solar collector is the \"heart\", it will light energy into heat, so heat up the water tank, so the tubes have the same external conditions, the amount of heat, the water temperature directly affects the level. Consumers in the purchase of solar water heater, to the \"winter useful\" as an important selection criteria.

    Second, look at insulation. Water heater tank is the \"water storage\", which is mainly reflected in the performance of the merits of insulation effect. Not only look good holding tank insulation thickness, but also the thermal insulation materials and processes. Water tank insulation thickness and tank insulation material is the ability to influence important parameters. Especially in the area north of the Great Wall, the proposed purchase insulation thickness of 60 mm or more brands of solar water heaters.

    Third, look at bearing strength. Solar energy stand as people\\ s \"skeleton\", fragile, of course not. Current application is more streamlined tower bearing, it uses an enhanced, high base, to overcome the traditional fine thin rod holder is not the lack of wind, wind, rain and snow resistant, anti-hail, corrosion-resistant .

    Four to see manufacturers and brands. Should be possible to choose a good reputation, product quality, after-sales service guaranteed brand products. At present, solar water heater industry was mixed, many small workshops assembly, the production of products in quality, performance and after-sales service are difficult to guarantee. Choose the strength of the professional manufacturers of brand-name products, allow consumers peace of mind, the best protection.

    For solar water heater problems, China Consumer Association recently held in Beijing and other units\\ use of solar energy in winter to solve problems, promote new industry standards mature \"seminar on how to resolve the current consumer reflects the strong solar hibernation issues in depth, make solar energy industry to establish standards, from the roots of the problem, regulate the industry and safeguard the interests of consumers.

    At the meeting, Huang Ming Solar Energy Co., a live demonstration of the winter, easy to use as a standard water heater product research and development of gold, so that participants can see a turning point. Participants believe that the emergence of water heater, the solar industry is expected to become a sign of maturity.

Selection Guide of are there?

The first took the stuffy drying heaters. This is a collector and heat storage combined with the overall heat storage water heaters, generally two to three blacked-tube structure, the black coating to absorb heat from the water can heat the advantage of simple structure, low cost; shortcomings is a fast heat, hot water can not be used overnight, during the winter and rainy days can not be used, this product was only used in some remote rural areas, has basically been eliminated.

    1, first on behalf of nausea drying heaters. This is a collector and heat storage combined with the overall heat storage water heaters, generally two to three blacked-tube structure, the black coating to absorb heat from the water can heat the advantage of simple structure, low cost; shortcomings is a fast heat, hot water can not be used overnight, during the winter and rainy days can not be used, this product was only used in some remote rural areas, has basically been eliminated.

    2, the third took the flat-plate . It consists of flat-plate collector tank, generally using natural circulation operation mode. Flat channel heat from the heat-absorbing body, a transparent cover, back and side insulation layer and the framework composition. Domestic flat body of the letter are endothermic heat of the blow up process rolling composite pipe made of copper and aluminum plate, copper (copper wood) tube plate, welded stainless steel metal forming and other flat box structure. They are guaranteed clean water, heat-absorbing body sunny with acrylic top coat anodized black or colored with selective coating; collector back and side of the insulation materials commonly used in polyurethane foam, mineral wool and polystyrene vinyl plate (thermal contraction phenomenon, must be padded with heat-absorbing glass wool or reflective body separated), with a specially designed multi-framework aluminum (glazing and sealing materials). 5mm glass with a transparent cover. Features: low cost, high thermal efficiency, can produce hot water when there is sunshine, but heat faster, larger heat loss in winter, rainy days and difficult to achieve a bath temperature requirements.

    3, the third took the vacuum tube water heater. It consists of multi-vessel glass vacuum tube directly into the tank structure, the general use of natural convection heat transfer. Each vacuum tube is placed between the hole and water tank made of silicone rubber seal. Vacuum tube does not take the water, by the copper heat pipe inside the superconducting heat transfer medium, and high thermal efficiency without furring. Most of the domestic water heater real glass tube, which consists of a diameter of 37mm, 47mm and 58mm high borosilicate glass made of concentric tube sealing, tube between the pump into a 5 × 10-3Pa vacuum deposition with the outer surface of inner tube nitrogen gradient aluminum / aluminum selective absorption coating solar spectrum (absorption ratio a = 0.90 ~ 0.92, firing more than Σ = 0.06 ~ 0.1), the tube length with 1.2m and 1.5m two. Vacuum tube collector heat loss coefficient (U = 0.55 ~ 1.2W/m2.0C), so use it to make solar water heaters in the winter even better thermal performance, for in the North and the South suddenly overcast and rainy days suddenly Yang weather use. Characteristics: high thermal efficiency, absorbs heat quickly, slow heat, heat loss, as long as the amount of solar radiation to meet the requirements, rainy days and winter can also be used, the appearance of luxury, durability, up to 15 years, small footprint, ideal for home use.
