Infinity® 20 Heat Pump With Greenspeed™ Intelligence 25VNA0 Taking Efficiency to the Next Level with Adaptable-Speed Technology The Infinity series heat pump with Greenspeed intelligence is the first of its kind. No other ducted, air source heat pump can beat its 13 HSPF rating for heating efficiency. It’s a winner too when it comes to cooling. But perhaps the biggest story is what it can do for your home comfort. Greenspeed intelligence pairs adaptable-speed technology with our Infinity control’s intelligence. The unique, variable-speed compressor of this unit, when managed by the Infinity control as part of a complete Infinity system, allows it to adapt its output to the needs of the home. With infinite adjustments between 40 and 100% capacity, it gives the home only the amount of cooling or heating necessary. This allows the system to operate longer at steadier, lower capacities, which ensures incredible energy efficiency and quiet operation with tighter temperature control than standard systems.
