-25 Ambient Temp. Cold Region Combining Type Air to Water Heating Pump Solution
-25 Ambient Temp. Cold Region Combining Type Air to Water Heating Pump Solution Features:
1) Combining design, big indoor unit with key conponents inside, never frozen, wildly be used widely even in -25DegC region, can be high COP reaching 5 above.
2) It meets +A grade above in ERP Energy Label according to EN14825.
3) Wide range of hot water temp. outlet: 35℃ to 55℃. With such ability, this device can accomplish low temperature space heating and high temperature space heating both.
4) We adopt intelligent control system to accomplish auto-alteration between sanitary hot water and space heating, firstly achieve 4-season hot water at 55DegC.
5)To prevent the spread of germs to harm human body, even death, control system of this series gives command to heat the water in storage tank to around 70℃ once a week.
At this temperature in water, more than 85% of germs are defunct. So the electric heater is required to install in water tank.
