How can the heating transition be achieved in areas where the large-scale expansion of district heating faces economic and urban planning constraints? In places where decentralised heat pumps are not feasible due to a lack of space or noise control requirements? It is precisely this question that is currently preoccupying many local authorities and municipal utilities following the completion of their local heating plans.
The presentation demonstrates how the Klimaturm – an innovative, vertically constructed large-scale air-source heat pump – can bridge the supply gap between centralised district heating and individual heat pumps. Depending on its capacity, a single Klimaturm can supply up to 400 flats in new-build developments or 200 flats in existing buildings with green heat. Its space requirements – equivalent to approximately two car parking spaces – and its whisper-quiet operation mean it can be deployed even in densely built-up, existing urban neighbourhoods. Intelligent control and storage technologies also reduce heat production costs.
The presentation focuses on practical experience gained from the commissioning of the first Klimaturm in June 2026 in Bremen, as well as the concept of the ‘Klimaturm swarm’ . Instead of having to make high initial investments in large-scale district heating networks, municipal utilities and local authorities can gradually connect neighbourhoods using climate towers and local heating networks, and link these together as demand grows. The presentation demonstrates how this concept can accelerate the implementation of municipal heating plans, reduce investment risks and enable an affordable heating transition.
