Key to choose liner thickness
Face a variety of brands on the market quite a mixed bag of , how to choose the inexpensive, good quality product?
The very fact that to buy a new solar water heater with the onset of winter, in a semi-dormant state in the morning no hot water, the hot water only at night, the family wash inconvenience. According to the Provincial Consumers Association a solar water heater usage survey, there are currently up 40.87% of the solar water heater can not be used to winter. In addition, 71.80 percent of consumers do not know how to identify the quality of the pros and cons of solar water heaters.
Face a variety of brands on the market quite a mixed bag of solar water heaters, how to choose the inexpensive, good quality product? In this regard, a certain brand of solar water heaters dealers Li introduced, the key was focusing on insulation and heat-absorbing case, such as the water tank to check the thickness of the host and the material density, the general thickness of higher density, thermal insulation effect is better; also can be observed transparency and light transmission rate of the vacuum tube, the relative transparency, good heat absorption is better. \"Insulation effect good chassis, slapped together, will issue a crisp sound.\" Solar water heater can not be used in winter there are two main reasons, lower collection efficiency is a factor, and pipe freezing is another major factor. Solar water heater collector to achieve through the collector, and is the most important parts of its coating, vacuum, lighting the area etc will affect the stability of the film collector effect. If the vacuum tube collector is poor, small size, can lead to ineffective collector. Provincial Consumers Association recommends that consumers buy solar water heater, to the \"winter useful\" as an important criterion. Freezing in winter to test the ability of solar water heater, water tank insulation and other aspects of performance, the best period, not to buy a small workshop production of \"three noes\" products. Do not arbitrarily replace or assemble solar energy host, auxiliary equipment, piping and other accessories or control system, in order to avoid disputes rights is difficult, or cause safety problems.
