was only 3 months quilt insulation package
Last May, Mr. Chen, who lives Wangchengpo special purchase of a common brand of . \"Who knows, after three months, holding on to die, large noon, hot water, at 9 pm on the cold was not a bath.\" Thinking still under warranty, then call the manufacturer Presbyterian, but the repairs did not last long after the boom. Repeated several times, Ch\\ en had this big guy wrapped in blankets, to enhance the insulation effect.
As the solar water heater market is relatively confusion, Provincial Consumers Association received many complaints, the Provincial Consumers Association relevant staff told reporters that consumers encounter such cases in addition to complaints promptly call 12315, buy their own solar water heater, it should grasp \" four key \"to avoid unnecessary trouble.
Buy solar \"four note\"
Provincial Consumers Association staff, at time of purchase, consumers first look at the effect of concentrating collectors. Currently, there are two tubes on the market, one is using the traditional gradient membrane tube manufacturing process, has a \"high temperature, anti-cold, more efficient,\" features three high vacuum tube, which is the former alternative, the water heater heat gain increased by 30% solve the traditional tube light in the rainy days when water temperature is not high enough, the winter temperature drops when solar energy is not good to use more problem.
Second, depending on insulation performance. Water heater tank is \"hot water storage.\" Not only look good holding tank insulation thickness, but also the thermal insulation materials and processes. Water tank insulation thickness in the tank insulation material impact force is an important parameter.
Third, look at bearing strength. Solar energy stand as people\\ s \"skeleton\", the current application is more streamlined tower bearing, it uses an enhanced ultra-high base, rod holder of traditional customer service does not thin the lack of wind, wind, rain and snow resistant, anti-hail, corrosion-resistant.
Fourth, look at the brand and services. Solar water heater host outdoors, exposed to the elements year round, needs professional repair and maintenance. The current domestic production of solar water heaters up to thousands of manufacturers, product quality varies greatly, some of the products quality tests, installation services are not in place, to the users trouble. Therefore, choose the strength of the manufacturers of the winning numbers are also important products.
Solar not buy the bigger the better
Provincial Consumers Association also prompt consumers to change the use of solar water heaters in error. Provincial Consumers Association staff noted that solar is not to buy the bigger the better. Buy a big price doubled, more can not afford to never use hot water. Reasonable method of calculation is the resident population by household water capacity, the family usually 50L / person, that according to (46-56) L / person calculated the most reasonable.
Bought not only for water heaters and bath water should be the life of the protagonist. With hot water to remove pesticide residues in vegetables, washing dishes when the oil has the ability to efficiently, can make full use of laundry detergent, washing can be used to protect the paint.
The use of solar water heaters in the winter is not good, can not use is a huge misunderstanding of consumers. Although the winter sun is not sufficient to produce the hot water temperature is low, but more than ten degrees higher than the water temperature, with a small amount of electric auxiliary heating, water heating than electricity or gas more economical electricity.
