Water Source Heat Pump (WSHP)
SmartSource® High-efficiency Horizontal WSHP

Models GSH, GTH

SmartSource water source heat pumps (WSHP), from 1/2 to 6 tons, combine industry-leading efficiencies with low-noise operation, high indoor air quality, and consistent air temperatures. 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 geothermal heat pump units perfect for LEED® projects and rebate opportunities.
