热水器企业对蓄热型电热水器这一产品并不陌生,许多人士都曾经研发过这种技术,还有一些企业也曾生产销售过这类产品。然而,由于蓄热材料的蓄热性能使用一段时间后就会衰减,导致产品寿命短,缺陷突出。一些发达国家研究了多年,也没有获得理想进展。 Water heater business is no stranger to the product of regenerative electric water heater, many people have developed this technology, there are some companies have also produced such products. However, due to the heat storage performance of thermal storage material will be used after a period of time will decline, resulting in short product life, outstanding defects. Some developed countries have studied for many years and have not made satisfactory progress.
