An energy label helps compare products under defined conditions. For a procurement team, the useful task is to check that two labels describe the same application, rather than treating A+++ as a promise about every installed system. This guide owns label interpretation; the seasonal-performance article addresses field measurement.
Matched performance data
COP is heat output divided by electrical input at an operating point. An A7/W35 figure describes a stated air and water condition; it cannot be compared fairly with a value taken at another temperature or system boundary. Request both output and input, not just the ratio.
Operating assumptions
SCOP describes seasonal performance under a standardized profile. Compare the climate, water-temperature application and supporting product fiche. An installed system may have different hot-water demand, pumps, backup use and weather. A measured SPF is not automatically equal to the label SCOP.
Rules and eligibility
Read the energy efficiency class and seasonal space-heating efficiency directly from the applicable label and fiche. Do not convert a SCOP into a label class using an unsourced universal threshold table. Individual products and packages can have different scope; hot-water performance is a separate question.
Supplier evidence and responsibilities
For a distributor comparison sheet, keep one row per exact model and record document revision, climate, temperature application, capacity at the local design condition and modulation. Missing data is a request for clarification, not evidence that a competitor performs worse. Keep running-cost scenarios separate from verified product figures.

Before requesting a project quotation
| Check | Information to prepare |
|---|---|
| Project scope | State the country, project type, operating conditions and required delivery date. Identify which decisions still need an installer or designer. |
| Topic-specific evidence | the energy label, product fiche and rating conditions |
| Responsibility and acceptance | Record who supplies, installs, commissions and services the equipment. Ask which documents and checks are included, and confirm exclusions in writing. |
This checklist helps define a request; it is not a model performance claim, installation design or promise of availability.
