SmartSource Horz High Efficiency
SmartSource® High-efficiency Horizontal WSHP

Models GSH, GTH

Now available with low-GWP R-32 refrigerant that increases efficiency using less refrigerant than typical R-454B refrigerant water source heat pumps (WSHPs), SmartSource combines high efficiencies, low-noise operation, high indoor air quality and consistent air temperatures for industry-leading performance. These WSHPs are exceptionally quiet (46 dBA) with EC motors that are standard on all units. They are ideal for schools, clinics, office buildings, multi-unit living facilities and other projects, both new construction and retrofit, where high efficiency is a key specification. High EERs that far exceed ASHRAE 90.1 standards make these heat pump units perfect for LEED® projects and energy-saving rebate opportunities.
