In the late summer and early fall, the urban retrofit geothermal project located at 248 Bryant Avenue in Syracuse, New York was completed. Pipes were fused and run into the basement and pressure tested. The wells were then grouted with a flowable cementitious grout (See Photograph 1).
Following completion of the site work, the mechanical contractor, Renaissance HVAC (Verona, New York), completed the installation of the 4-ton GeoStar Cypress Combination heat pump see Photograph 2). Wells were completed by purging and filling with a 20% ethylene glycol solution for freeze protection. The combination heat pump system allows the heating of the house both with air and radiant hot water and air conditioning in the summer. The geothermal heat pump will be powered by the grid-connected 6.4 kW solar array mounted on the home’s rooftop.
Piping and the heat pump system were provided by Phoenix Energy Supply who, along with Renaissance HVAC, also provided tremendous support on this challenging project! The next steps on the path to net-zero are to connect domestic hot water to a heat pump and switchout the natural gas fueled stove and oven!
