Today, the Heimeier brand is a key pillar of IMI Hydronic Engineering, which is part of the UK-based IMI plc. Most of its core thermostatic components continue to be manufactured at its historical base in Erwitte, Germany. The brand emphasizes energy efficiency and precision control within residential and commercial HVAC systems, maintaining a dominant market share in central Europe.
