Independent Trade Directory for Heating & Heat Pumps in Germany.

Our Mission: Clear Guidance for Heating Modernization

Heating installation and heat pump transitions in Germany are governed by complex GEG requirements (Heizungsgesetz) and KfW subsidy regulations. heizungruf.de connects building owners with verified, certified local heating engineers (Heizungsbauer & SHK-Meisterbetriebe).

Every profile includes verified contact details, specialization in heat pumps (Luft-Wasser, Erdwärme), hybrid systems, solar thermal, and authentic Google Maps review counts without commercial paywalls.

Quality Assurance & Real Business Data

We combine continuous automated validation with manual trade verification:

• Real Business Verification: Direct integration with Google Maps business listings and public company registries.
• No Paid Placement Bias: Ranking reflects regional relevance and real ratings, never hidden sponsor fees.
• No Fake Reviews: Unrated businesses are clearly labelled; no fabricated reviews or synthetic scores are ever used.
