Installer Resources - Modern Wood Heating

MassCEC provides grants for the installation of modern wood heating systems at residential, commercial, industrial, institutional, and public facilities. This page provides resources for modern wood heating installers and designers about the process of applying for both residential and small-scale and commercial-scale grants.

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

Residential and Small-Scale Installer Emergency Replacement Resources

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.
  • Peak heat load on the application matches the Manual-J software output and is for the appropriate design city
  • The heating system’s configured capacity is less than 110% of the building’s Manual-J design load.
