Heating System Performance Factor (HSPF) is a similar metric determined by measuring heat transfer rates during the heating season.
(6.) Tier I air source heat pumps have at least 14.5 SEER and 12 EER and 8.2 HSPF. Tier II air-source heat pumps have at least 15 SEER and 12.5 EER and 8.5 HSPF.
Additionally, the changes affect the FTC EnergyGuide label (yellow "hang tag") attached to the heating and cooling system which contains SEER and HSPF ratings for the unit.
HSPF model requires the input data including digital elevation model (DEM), land use, soil data, and meteorological data.
Introduction to HSPF and the Model Application Process.
We offer products up to 23 SEER and with HSPF ratings up to 11.9 in a variety of fan coil types and compressor technologies, which allows our customers the flexibility to pick the right product for the right application," said Bob McDonough, president of Carrier Residential and Light Commercial Systems.
The heating efficiency is taken into account within the HSPF (heating season performance factor) rating The main point I'd like for you to understand is that both of these efficiency related numbers refer only to the piece of mechanical equipment.
The units feature efficiencies up to 13.00 SEER and 7.70 HSPF (Region IV) for operating cost savings.
The heating-season performance factor (HSPF) indicates the heating efficiency.
The new SH10B heat pump from Ducane has a 10 SEER cooling efficiency, two- to five-ton cooling capacity, and cools and heats quietly up to 7.00 HSPF. Its scroll compressor has fewer moving parts for quiet operation and an insulated cabinet delivers superior sound control.
