01

Official sources first

Figures come from public registers such as the German BAFA heat pump list, the Dutch RVO ISDE equipment list, the UK OZEV charger scheme, the ENA inverter register and the EU EPREL energy-label database, then manufacturer datasheets.

02

Every value traceable

Each specification shows where it came from and when it was checked, so you can verify it yourself instead of relying on marketing claims.

03

Rules per country

The same heat pump or charger is judged against local rules: noise distances, subsidy and grant eligibility, and smart-charging requirements.
