Ground-Source Heat Pump Installer Resources

MassCEC provides grants for the installation of ground-source heat pump (GSHP) systems at residential, commercial, industrial, institutional and public facilities. This page provides resources for GSHP installers and designers about the process of applying for both residential and small-scale grants and commercial-scale grants.

  • A residential/small-scale GSHP project has a heating capacity of up to 120,000 BTU/hr.
  • A commercial-scale GSHP project has a heating capacity over 120,000 BTU/hr.

Best Practices

MassCEC’s program requirements are intended to ensure high-quality project designs and installations. We recommend double-checking the following to make sure the system meets program requirements and to minimize the delays associated with these common application errors:

  • You have included all documents on the application checklist.
  • You have recorded nameplate heating capacity, COP and EER correctly from the AHRI certificate, and the certificate is for the correct heat pump model. 
    • This is the most common application error.
  • Peak heat load on the application matches the Manual J software output and is for an appropriate design city.
  • AHRI-rated heating capacity is between 90 percent and 120 percent of peak load.
  • Bore grouting has a grout conductivity equal to or greater than anticipated earth conductivity of the drill site, up to 1 BTU/hr-ft-°F.
  • Bore hole depth is at least 150-feet-per-heating ton.
  • Horizontal-loop system design drawings are accurate.
