Who must maintain a copy of a heat load calculation?

The requirement for maintaining a copy of a heat load calculation falls upon the licensee, who is generally the individual or entity holding the necessary credentials to perform heating system installations. This responsibility ensures that the heating system is designed based on accurate calculations of the building's heating needs, taking into account factors such as insulation, square footage, and climate conditions.

By retaining this documentation, the licensee can provide evidence of compliance with local building codes and regulations. It also serves as a reference for any future modifications, maintenance, or troubleshooting related to the heating system, promoting accountability and professionalism in the work performed. This practice helps to ensure that the heating system operates efficiently and safely, ultimately benefiting the property owner and occupants.

While contractors, property owners, and local authorities may all be involved in the process of heating system installation and inspection, it is the licensee who is specifically tasked with the responsibility of maintaining these critical calculations.
