In late 2025/early 2026, Natural Systems Engineering (NSE) completed a design and installation of a 3-ton water-to-air ground source heat pump (GSHP) system in DeWitt New York.  The heat pump is a Geostar Sycamore system and the ground loop consisted of one 350-ft vertical closed loop with 1.25″ HDPE piping and thermal grout.  

For this project we worked with partners Utter Well Drilling (Lodi, New York) and EMM Heating Services (Croghan, New York) for the ground loop and the heat pump install, respectively.  

The ground loop design report, energy model, and rebate application along with supporting documentation were prepared and submitted by NSE to support the National Grid Clean Heat Program rebate application. This system was one of the first to leverage the latest Clean Heat Program rebates for 2026 of $20,000 (!) for full-load installations.
