Manufacturer, Exporter and Wholesale supplier of Heat Pump Water Heaters (HPWH). Rather than generate heat as an electricity resistance heater does to deliver hot water, a heat pump water heater moves heat from air through a refrigerating cycle and releases it into water, thus saving electricity by up to 70 percent. According to strict lab test results, even at an ambient temperature of as low as -10ºC or as high as 43ºC, our HPWHs still work reliably with a 2.0 plus COP value. The chilly winter of 2004 proofed that the performance of our HPWH is incomparable in China market, while other manufacturers encountered serious defrost problems.
