A twin rotary compressor is the detail that separates a good small air to water heat pump from an average one: two offset rotors balance each other, which cuts vibration and lets the unit run at very low speed without the pulsation a single rotary produces. That is what makes low-load winter operation efficient. 3KW, 5KW and 7KW on R290 at Class A+++, galvanized housing with a two-year warranty.
