Required Documentation:
• Proof of Existing Conditions: Photographs or documentation showing the current uninsulated state of the piping.
• Project Details: Detailed description or invoice of the insulation project, including the type of insulation used, total linear feet and confirmation of R-4 minimum insulation requirement.
• Verification of Fuel Source: Documentation confirming that the building’s space heating and domestic hot water are generated by natural gas-fired equipment.
Important Consideration:
• The bare pipe size must be 0.5-inch to 2.5-inch nominal pipe diameter. For piping of 3 inches or more nominal pipe diameter, apply in the custom section at the bottom of this application.
-
Applicability: Eligible for retrofit projects only.
-
Qualifying Efficiency Requirement:
-
Projects must use natural gas as the primary fuel source for space heating and/or domestic hot water production.
-
A minimum of R-4 (approximately 1 inch) of insulation is required to be added to existing bare metal piping systems.
-
The project must involve the insulation of a minimum of 10 linear feet and a maximum of 500 linear feet of piping.
-
Acceptable insulation materials include high-density fiberglass insulation or closed-cell elastomeric foam insulation, specifically shaped for piping applications.
-
Exclusions:
- Projects utilizing dual-fuel systems or where electricity serves as a backup or redundant fuel source.
- New construction projects.
- Pipes that are already partially insulated (more than R-0).
- Projects in non-conditioned spaces.
- Newly installed or recently repaired piping systems.
• Other requirements:- Insulation must be installed in conditioned spaces that are heated during the winter using electricity.
- The domestic hot water and/or space heating for the building must be generated by electric equipment, such as boilers or hot water heaters.
