Heat-Pump Performance Data Reference
Find dependable inputs. Keep the operating conditions attached.
Explore sources for SEER2, COP17 and COP47, identify matched heat-pump systems and evaluate performance at defined operating conditions.
Source directory and equipment file review
Equipment records and performance summaries: to be provided. Sources reviewed: .
Heating at 17°F
Dimensionless heat output / electrical input at a stated operating point. Rated and maximum output differ.
Heating at 47°F
The same ratio at a different outdoor temperature. Match indoor conditions and power boundaries too.
Interpreting SEER2 and heating COP
There is no universal mathematical conversion from SEER2 to COP17 or COP47. Dividing a seasonal efficiency by 3.412 changes its units; it does not produce a heating COP at a particular temperature. Seasonal cooling efficiency and heating performance at a specific temperature must be evaluated separately.
For a single documented heating point, COP = heating capacity (Btu/h) ÷ 3,412.142 ÷ electrical input (kW). Both inputs must describe the same conditions and power boundary. A ratio calculated from reported values must be labeled as derived; it is not automatically a certified rating.

Performance data sources
Use the source descriptions to assess data coverage, access options and reuse requirements.
NEEP Cold Climate Heat Pump Product List
The reporting specification covers heating capacity, electrical input and COP at 17°F and 47°F, with separate minimum, rated and maximum operating points. Check each equipment record for the values reported.
- What it represents
- Cold-climate selection, not a sample of the entire market. Laboratory or engineering data in the extended table must not automatically be called AHRI-certified.
- Access options
- Enhanced subscriber access includes unlimited downloads of reported product performance information. Consult NEEP for the access arrangement applicable to your use.
- Use and attribution
- Commercial website display, redistribution, downloads and derived summaries need written permission. Public availability or subscription does not establish those rights.
AHRI Directory of Certified Product Performance
Use the exact matched indoor/outdoor combination and AHRI reference to check certified ratings. Do not assume every extended operating point is a certified field.
- What it represents
- Certified matched-system ratings. Confirm the available temperature-specific COP and electrical-input fields for the relevant equipment category with AHRI.
- Access options
- Public CSV export is limited; licensed access provides full export, with an optional Unitary API. Confirm the field definitions and API coverage for the intended analysis.
- Use and attribution
- AHRI explicitly requires a signed data license for reuse in websites, software or databases. Its FAQ also says static certificate copies should not be included in applications or catalogs.
Manufacturer engineering submittals
Request extended heating tables for exact matched systems: capacity, electrical input and COP at the same temperature, speed and airflow.
- What it represents
- Record model suffixes, furnace/air handler, refrigerant, power boundary, test procedure and whether defrost or auxiliary heat is included.
- Access options
- Engineering submittals and extended performance tables may be available through manufacturer technical libraries, representatives or technical support.
- Use and attribution
- Obtain written permission for website display and any redistribution or aggregated use. Preserve document revision and page/table reference.
DOE Heat Pump Field Database
A separate source for field studies and operating measurements, not a substitute for certified 17°F/47°F ratings.
- What it represents
- Site, weather, controls, sampling interval, installation and supplemental heat affect measured results. Keep each study and its boundary separate.
- Access options
- The NREL 2021–2023 cold-climate study page provides site-level links to raw, formatted and hourly data. Review the study methodology and file documentation when selecting observations.
- Use and attribution
- Review each study’s license, attribution and privacy requirements before reusing its measurements.
HeatpumpMonitor.org
Explore monitored heat-pump systems and their operating results on the original source website.
- What it represents
- Community field observations depend on installation, weather, hot-water use and the stated metering boundary. They are not certified SEER2, COP17 or COP47 ratings or a representative market sample.
- Access options
- Use the source website to inspect systems, time periods, measurement boundaries and data coverage.
- Use and attribution
- Source link only: EngineersUniverse does not reproduce this collection. Consult the publisher’s licensing and usage information for any further use.
Comparing heat-pump performance
Group systems by equipment configuration, compressor type and nominal capacity before comparing their performance. Keep compact ducted, ductless single-zone and multizone systems in separate groups. Preserve every matched indoor/outdoor model and furnace identifier; do not treat a nominal outdoor unit as a complete matched system.
Confirm public display, downloads, derived statistics, attribution, refresh terms and removal obligations in writing.
Keep certified seasonal ratings separate from manufacturer extended points. Record temperatures, output level, airflow, static pressure, defrost and auxiliary heat.
Verify documents and dates, remove duplicate matches and disclose selection bias before summarizing.
Sample coverage and variation. Statistical summaries should disclose unique-system count, manufacturer count, missing-value count, date range, mean/median and variation for each compatible group. A model-count average is not a sales-weighted market average. Cold-climate eligibility and repeated indoor matches can bias a sample.
Check a file before using its values
Load your own permission-cleared JSON file to inspect matched systems and compare reported conditions. This tool processes the file in this tab, does not upload it, and does not save it after you leave or reload. Importing is not verification or publication approval.

What does the template require?
One exact matched system per record; nominal capacity in Btu/h; separate source entries for certified, extended and measured data; SEER2 with its source; separate heating points at each temperature and output level; capacity in Btu/h, total input in kW and reported COP. Unknown numeric values must be null, never zero. Use “unknown” for undocumented condition descriptions.
Complete the blank template with sourced equipment values and documented conditions before opening it for review. Review and permission fields record the information supplied in the file; independent verification is required before publication or reuse.
Equipment data review standards
Equipment records intended for publication require a documented source and a consistent technical review:
- Traceable equipment identity: exact indoor/outdoor model combinations, applicable furnace identifiers and source references.
- Defined performance conditions: SEER2 and heating capacity, electrical input and COP at stated temperatures and output levels, with units and test procedures identified.
- Source verification: independent checks against the original documents, including revision dates and operating-point definitions.
- Controlled use and maintenance: documented reuse permissions, duplicate checks, sampling methods, updates and corrections.
Manufacturer-neutral summaries also require a comparable sample, disclosed coverage and measures of variation. The local workspace supports file review; publication and reuse permissions require a separate review.
