Customers keeping their wood or solid fuel heating system in safe and working order may submit a level 1, 2, or 3 WETT inspection report, based on the recommendation from your WETT-certified professional. The inspection report must be dated within the 12 month period before or 6 month period following the date of the heat pump installation invoice and include the inspector’s WETT certification number, the site address of the wood or solid fuel heating system, and whether the installation is compliant with relevant codes.
