AQUECOIL HHU-GS-2 (21” x 21”) Heating Coil, Hydronic, C-Cab, Light Gray.

This AQUECOIL™ Hydronic Heating Unit measures 21" x 21 3/4" (fits 21" x 21") and works in conjunction with your preferred brand of Air Handler, and a hot water source, to provide residential space heating.

 It extracts BTUs from the hot water and uses the Air Conditioning Air Handler to distribute the heated air throughout the conditioned space. The AQUECOIL unit is designed to fit over the Air Handler's discharge or return in either horizontal or vertical applications. 

The AQUECOIL unit eliminates the need for a furnace or heat pump to provide space heating. Not only does the AQUECOIL unit offer a low-cost alternative to conventional space heating equipment, it also provides substantial heating capacity, at an attractively low fuel cost, when used with a high-efficiency hot water heater or boiler.
