The Envision Series
Nearly 25 years ago WaterFurnace led the way by designing and manufacturing water source heat pumps for use in 
geothermal closed loop applications. In 2003 WaterFurnace developed the first R410A water source heat pump product 
line. Now the Envision Series breaks ground again by providing the first 30 EER and 5 COP (ISO 13256-1 GLHP) and the 
first 20 EER 6 COP (ISO 13256-1 WLHP) rated water-source heat pump on the market. Higher efficiency also means less 
heat rejected and ultimately shorter earth loops. WaterFurnace quality is well known and respected and is a result of 
quality engineering and manufacturing in the state of the art Fort Wayne, Indiana plant. The Envision Series provides:
Highest efficiencies and lowest operating costs.• 
Broadest R-410A product line.• 
Standard or extended range (geothermal) operation.•
