Heat pump water heater is necessary to configure the electrical auxiliary

How much energy a heat pump water heater can handle depends on the economics of the heat pump product. Unit energy consumption within the heat pump water heater carrying more energy, indicating the better energy-saving effect, the greater the economic value; Conversely, the effect is worse, even without direct electric heating of the energy generated, such products have been There is no energy value, so there is no economic value at all. Measure the energy efficiency of products generally use energy ratio. Many people say that the heat pump water heater will be more than 1, and much higher than the electric heating, so do not need to use electric auxiliary. As a result, many manufacturers and distributors are quietly using electricity aids as heat pump water heaters fail in winter due to the lack of electrical assist. Heat pump water heater want to get a comprehensive promotion, can not do without the support of electrical assistance, electrical assist is also easy to use clean energy, the system is naturally one of the preferred objects supporting the auxiliary heat source. In fact, the use of electric auxiliary heat pump water heater has almost become the conventional configuration of the heat pump water heater electric auxiliary advantages: 1, heat pump water heater at low temperatures when the unit heat is too small, the heating rate is too slow, hot water supply Can not be guaranteed If electrical assist is used, the hot water supply speed can be increased without reducing the overall energy efficiency of the system. (In this case, the power of electric heating has no direct relation with the performance parameters.) 2. The working process of the heat pump water heater at low temperature has exceeded the optimum working range, the work efficiency is low, prolonged use will seriously damage the service life, Electric auxiliary, can reduce the work in this case the operation process can effectively ensure the service life of the product 3, by configuring the power of larger electric auxiliary heating equipment, both to improve the hot water supply speed, but also appropriate to reduce heat pump unit Compared to reduce construction costs, is conducive to heat pump product marketing.
