Recently, the China Consumers Association conducted a comparative test on the safety and performance of some branded water storage electric water heaters sold in the market, involving 25 models of water storage type electric water heaters of 20 brands. One of the sample nameplates has no manufacturer name, and the measured values ​​of the inherent energy consumption coefficients of the two samples do not match the explicit values. It can be seen from the results of the comparative test that the safety quality of the storage type electric water heater products currently on the market is high, and the performance of most of the storage type electric water heaters can be consistent with the explicit values, but the 24-hour inherent energy consumption of individual samples. If the coefficient is too high, the company needs to improve in time to improve quality.
The China Consumers Association reminds consumers to recommend that consumers purchase storage-type electric water heaters as much as possible to purchase products with large sales and high brand awareness from regular sales channels. At the same time, they should choose storage-type electric water heaters with CCC mark. product.
According to the installation method, the storage type electric water heaters are divided into three types: wall-mounted horizontal, wall-mounted vertical and floor-standing. The power also has various specifications. When purchasing, you should choose the product that suits your needs according to the actual needs of the family.
The product logo should be complete, including the company name, specification model, voltage parameters, power parameters, rated pressure, etc. The installation instructions for the appliance should have detailed instructions for installation and operation, detailed maintenance methods, etc. The water mark should be clear and securely fixed.
Good quality appearance of the paint is uniform, bright color, no shedding, no dents or severe scratches, crush marks; various switches, knobs are beautiful in appearance, fine processing; the writing marks such as the dial should be clear.
In addition, the product packaging box should be complete and firm, the manual, certificate of conformity, warranty card are complete, and the accessories are complete. Pay special attention to the energy efficiency mark. The general energy efficiency mark will be stuck in the conspicuous position of the outer casing. Consumers should pay attention to whether the product model of the energy efficiency mark is consistent with the model of the water storage type electric water heater to be purchased. The smaller the energy efficiency rating in the middle of the energy efficiency indicator, the higher the energy efficiency rating and the lower the energy consumption. The "24-hour intrinsic energy consumption coefficient" in the lower part of the energy efficiency sign mainly reflects the thermal insulation performance of the water storage type electric water heater. The lower the value of the coefficient, the better the insulation performance of the model product, and the habit of using the water storage type for a long time. For consumers who plug the water heater power plug into the socket, the better the insulation performance, the less the number of repeated heatings per unit time, the more power saving.
The "hot water output rate" is mainly reflected in the ability of the water storage type electric water heater to provide hot water. The higher the hot water output rate, the higher the utilization rate of the hot water in the inner tank of the storage type electric water heater, one continuous supply. The more hot water there is. Consumers should choose a suitable storage type electric water heater according to factors such as the number of users, frequency, and winter water temperature.
