Overview

• The units will replace conventional heating in Vonovia’s housing where no district or local heat connection exists.
• Thirty systems are slated to be operating in Germany by the end of 2025, with more than 1,000 planned to supply heat to over 20,000 apartments by 2029.
• Each cube integrates an air‑source heat pump and core heating components, fits on a parking‑space footprint, includes noise protection, and is intended to run on rooftop solar power.
• EnerCube developed the technology, and DFA in Aachen will handle series manufacturing following a pilot phase.
• The companies report a Donauwörth pilot cut tenants’ energy costs by about 40 percent, and Vonovia presents the rollout as part of its 2045 climate strategy that drew praise from NRW minister Mona Neubaur.
