ALDI Farmington, NY
ALDI has a less-is-more approach to grocery retailing, and everything they do, from selecting suppliers to scouting locations to building and operating stores, facilitates savings substantial enough to impact the every-day living of its customers.
Geothermal heating and cooling is a natural fit for ALDI, and Eagle Mountain worked with ALDI to design and install a geothermal heating and cooling system for its location in Farmington, NY.
ALDI, Eagle Mountain, and APD Engineering & Architecture collaborated to design and implement a geothermal heating and cooling system with an anticipated payback period of 7.3 years. The Farmington, NY location is ALDI’s first store with geothermal, and this project will be used as a case study for future implementation of geothermal heating and cooling technology.
Geothermal System — Ground Loop
The Farmington, NY site utilizes 3 horizontal slinky geothermal loopfields. The loopfields are 132 feet long and vary in width based on the number of loops. Two 8-loop fields are located under the parking lot and a smaller 2-loop field is located behind the store in a grassed area. Redundant circulators can be seen in the following photo:

Geothermal System – Heat Pumps
The geothermal system operates with two 12 ton and one 4 ton horizontal water-to-air Geomax geothermal heat pumps suspended from the ceiling. A custom designed hydronic pump panel connects the two 12 ton units to the loopfield, and a standard pump pack supplies the smaller 4 ton heat pump. Hot and cool air is distributed through ducting.

Geothermal System – Heat Recovery Ventilation (HRV)
The ALDI store uses 2 Fantech Heat Recovery Ventilators (HRV) to increase operational efficiency of the geothermal HVAC system. HRV units exchange heat between intake and exhaust air, avoiding wasted energy from exhausting conditioned air.
