3kw Air to Water Heat Pump for House Water Heating

3kw Air to Water Heat Pump for House Water HeatingThe 3kw Air to Water Heat Pump for House Water Heating has been built in a waterpump for hot water circulation between the water heat exchangerinside the heat pump and an external 80Ltrs to 500Ltrs hot watertank where hot water stored and ready for use in 24 hours.FeaturesConvenient and High EfficiencyCompact design with small dimension makes the heat pumpthat is convenient to be delivered, stored and installed at anyplace, especially for apartment, villa house, beauty saloon,restaurant, hostel and hotel.Save EnergyThe heat pump has good quality and optimized refrigerant system with high COP up to 4.5 which means when inputs 1kW electricity and 4.5kWheat energy transferred to heat up hot water, save up to 70% energy bill. Variable ApplicationsHeating capacity range from 3.5kW to 7.5kW, the heat pump delivers 75 to 160 liters per hour hot water to hot water storage tank as individual system, also it works together with electric geyser and solar water heater as backup and combined system, in order to obtain best efficiency. System Operating Process1. Tap water goes into water tank; 2. Water pumped to heat pump; 3. Water heated in heat pump and pumped back to water tank for storage, and repeat process 1-3; 4. Hot water 55°C ready for use; Note: Water tank need to be ordered separatedly.ComponentsNo.Part NameNo.Part NameAController systemEWater heat exchangerBCompressorF4-way reversible valveCFan grid/ fan blade / fan motorGExpansionDWater pumpHAir heat exchanger Technical ParametersModel003005007Nominal Heating Capacity 1)kW3.557.5Nominal Power Input 1)kW0.831.151.71COP 1)w/w4.24.34.3Max.
