HERS Verification of Heat Pump Capacity
When heat pump systems are installed, and verification of the installed heat pump system capacity is required, the installed heat pump equipment shall be verified according to the procedure specified in this section. The verification shall utilize certified rating data from the AHRI Directory of Certified Product Performance at http://www.ahridirectory.org or another directory of certified product performance rating approved by the Energy Commission for determining compliance (product directory).
The procedure shall consist of visual verification of the model numbers of the installed system equipment and confirmation that the installed equipment is rated to provide the required heating capacity:
A. Record the manufacturer name and the model the number of the outdoor unit or package unit.
B. Record the manufacturer name and the model number of the inside coil if applicable.
C. Record the name of the product directory used to certify the system performance.
D. Record the certification number of the installed system if the certification number for listed products are published by the product directory.
E. Record the system's rated heating capacity at 47 degrees F published by the product directory.
F. Record the system's rated heating capacity at 17 degrees F if the value is published by the product directory.
If the installed system rated heating capacities at 47 degrees F and 17 degrees F are equal to or greater than the values specified on the Certificate of Compliance, the system complies. If the product directory does not publish capacity ratings at 17F, then compliance with capacity at 17F is not required.
