Thanks to Kolant Epoch-Making new technolgy, Kolant new heat recovery heat pump efficency (COP) is up to 7.0 when central cooling + hot water; COP is up to 5.0 when central heating+hot water. It means 1KW electricity input equal 7KW output. 
Kolant Central Heating+Central Cooling+Domestic hot water with heat recovery Heat Pump available for 7KW,10KW,14KW,17KW,20KW,25KW,30KW,40KW,50KW,60KW Product Function: Central Heating, central cooling and domestic hot water function in one solution. Provide free hot water when cooling
5. Economic: The running cost of Kolant heat pump can be 85% less than that of a traditional gas boiler heating system; 6.Advanced timer setting function for heat pump: Single day timer and Weekly timer are both available.Can be different setting for every day of the whole week. 7.Phone remote control function for heat pump is optional Control the operation and check the operation mode through simple phone call. 8. Historical record for all heat pump operation for long years. Heat recovery heat pump technical data:
