By replacing the existed central hot water devices such as electric boilers, oil boilers etc, morethan 70% of the energy required for domestic hot water can be taken form renewable source instead of electricityheating or fossil fuel burning. This almighty heat pump also can be used as an energy saving heating device inmany places, e.g as a second heat source of a solar heating system.ModelKRS-35B/N2KRS-50B/N2KRS-72B/N2KRS-90B/N2-LPower supplyPh-V-Hz220V/1PH/50HZ220V/1PH/50HZ220V/1PH/50HZ220V/1PH/50HZWorking tempºC-15ºC~43ºC-15ºC~43ºC-15ºC~43ºC-15ºC~43ºCMax. outlet Water temp.ºC60ºC60ºC60ºC60ºCWater Heating (A20/W55)CapacityKW3.557.29Hot water yieldL/h75107155193.4651763InputKW0.91.281.792.31COPW/W3.893.914.02 Rated currentA3.975.88.2311.17Hot water yieldm3/h    Max. input consumptionKW1.311.862.603.3Max. input currentA6.28.912.416.02631579Starting currentA18283561set Temp.ºC25~6025~6025~60 Water systemmaterials of water pipe copper copper copper copper water flowm3/h0.81.11.51.934651763Water different pressureKpa60506060Diameter,water inlet pipemmDN20DN20DN20DN20Diameter,water outlet pipemmDN20DN20DN20DN20Design pressure Mpa4.2/0.024.2/0.024.2/0.024.2/0.02Gas Weight (R410A)g    Outdoor noise level  (1 meter)dB(A)52535455Outdoor unitDimension(L*W*H)mm750*264*493935*282*5451002*302*6201002*350*620Packing(L*W*H)mm   1075*380*650NG/WGkg   73/87Warranty For the UnitMonth    NOTE1% free spare parts provided for maintenance(min order 20ft container, but mix less than 3 models, less than min order, no free spare parts provided).Testing condition: ambient Dry/Wet Bulb Temp.: 20ºC/15ºC; Water Inlet/Outlet Temp.: 15ºC/55ºC.
