For our heat pump group procurement in the Wörrstadt municipal association, which attracted 163 participants, we have a clear winner in the selection process:
Bernhard Frondorf Systemtechnik GmbH from Alzey

The owner-managed specialist firm stood out clearly from five other qualified competitors – particularly in terms of price, efficiency, scope of services and ability to deliver.

💡 What makes Frondorf special:
- A master craftsman’s company since 1968
- Proven expertise in heat pumps
- Around 95 employees (including 2 HVAC engineers, 2 refrigeration engineers and around 10 electricians)
- Financially sound and reliable
- Excellent references and customer reviews
The team has already been working on the realisation since the beginning of March:
Numerous personal consultations have already taken place to ensure that all interested participants can receive an offer by the end of April – demand is high.
In Frondorf, we have a partner on board that combines quality, scalability and reliability – all of which are crucial for a successful large-scale roll-out of heat pumps.
