WaterFurnace NS-030 Envision Single-Speed Heat Pump

WaterFurnace Envision products established a new industry standard for efficiency, performance, reliability and quiet operation. Envision products are performance-certified to ARI ISO 13256-1 standards, are ETL listed, and are ENERGYSTAR® qualified. This model is available with either an ECM or PSC motor (an ECM [Electronically Commutated Motor] is a high efficiency [65-72%] programmable brushless DC motor that utilizes a permanent magnet rotor and a built-in inverter. A PSC [permanent split capacitor] induction motor is less efficient [12-45%]). It can be installed either as as a water loop, a ground water closed loop, or a ground loop. These options result in a range of capacities and efficiencies. The specifications below are for the ground loop configuration with an ECM fan motor.
