ALFÉA EXTENSAAIR TO WATER HEAT PUMP• Six models: 5 to 16 kW single phase• COP (coeffi cient of performance) up to 4.5• Suitable for new build and renovationIndoor hydraulic moduleOutdoor inverter unit

Alféa ExtensaA LOW TEMPERATURE SOLUTION FOR TAILOR MADE APPLICATIONSLOW TEMPERATURE SOLUTION FOR TAILOR-MADE APPLICATIONSCOP to 4.5, Class A low consumption circulating pump, optional 1 or 2 zone(s) management, domestic hotwater production, cooling option; Alféa Extensa is the all-round low temperature solution in the Alféa range.Very easily adaptable and highly performant, its design and option range make it a benchmark in the heating sector!PERFORMANCE COEFFICIENT (COP)COP is an indicator of the heat pump performance. It correspondsto the difference between the amount of heat generated by the heatpump and the energy consumed for the equipment to work. A COP of4 means that the heat pump generates four times what it needs tofunction. So the higher COP is, the more performant the heat pump is.A SPLIT HEAT-PUMP FOR IMPROVED PERFORMANCESIndoor hydraulic moduleOutdoor inverter unitCHARACTERISTICS• Patented, coaxial heat exchanger andClass A low consumption circulating pump• COP up to 4.5• Water curve control for 1 to 2 zone(s)management• Possible to manage 1 hydraulic zoneand 1 electric zone from the heat pump(option)• Easy to install: ergonomics of hydraulicmodule (fast access to all components)• Complete programming functions includedSUPPLIESInverter outdoor unit:• Refrigerant circuit (R410A)• Scroll or Twin Rotary compressor(depending on model)• Full Inverter controlIndoor module:• Coaxial immersed exchangerin buffer tank• Class A circulating pump• Water curve control (ambient sensoras option)• Outdoor sensor• Expansion vessel, pressure meter, etc.• Auxiliary electric back-up (optional)2
