Hafencity Hamburg

With HafenCity, a new city quarter has been created in the heart of Hamburg. It is currently the largest inner-city development project (155 hectares) - and it is setting standards throughout Europe with its mix of apartments, offices, recreational facilities, retail trade and culture. The goal for HafenCity was to develop an energy supply concept that fulfilled the strictest economic and environmental requirements, and the city planners chose a solution based on the combination of the existing, well-proven Hamburg district heating system with decentralised, local heating distribution units. Danfoss has been the main supplier of District Heating components and units.

Unless a specific supplier has been asked for, Danfoss has been chosen as the default supplier of units and components for the project. “If the operator or planner does not specifically request a different manufacturer, we always choose Danfoss products. They offer a good balance of technology, performance and price,” says Olaf Ebeling, heating supervisor on the project.

In HafenCity, Arne Stüber Heizung und Sanitär GmbH has installed Danfoss equipment in several new buildings in the “Am Kaiserkai“ area – the complete district heating transfer station in buildings No. 33, 31, 29 and 27. This included projects with underfloor heating and others with radiator heating - Danfoss controls are easily fitted in both versions.

Project manager Judith Huber-Jahn, Reese Beratende Ingenieure, also sticks with trusted products for control of district heating and domestic hot water supply: “Given a choice, I would certainly opt for Danfoss products. The quality of the equipment is outstanding, and the available service and support is also a big plus. For more complex installations, Danfoss specialists help us with questions regarding the construction and design. And if something does not go according to plan on a construction site, Danfoss employees are on hand to come and advise us on site.”
