Johnson Controls has delivered Germany’s first seawater heat pump , a highly efficient system that will supply a new district in Neustadt in Holstein with thermal energy from the Baltic Sea . The innovative SABROE DualPAC turns seawater into a heat source for district heating networks, contributing to the decarbonisation of buildings in the country.
The system, developed in Denmark, provides up to 700 kW of power in winter conditions . During the coldest days, when the water temperature drops, the DualPAC can extract around 500 kW of thermal energy , which is then boosted by electricity before being distributed into the city grid.
The technology will enable the port of Neustadt to have a stable supply, integrating green energy and reducing the use of fossil fuels. At times of high demand, the system will be supplemented by a nearby waste incineration plant and a heat storage facility .
New heat pump reduces emissions in Europe
Johnson Controls, world-renowned for its smart building solutions, has highlighted that heat pumps represent a key technology for the electrification of heating systems . David Emin, managing director of the company in Germany, said: “ This project is a clear example of how we can take advantage of available natural resources to reduce carbon emissions .”
With the implementation of this seawater heat pump, the municipality of Neustadt is positioning itself as a benchmark in Europe’s energy transition . Thomas Anthoni, project manager for the municipality’s heating system, said that this technology ” marks a breakthrough in the use of environmentally friendly solutions in Germany .”
Eco-friendly heating systems for European cities
With over half a century of experience in designing environmentally friendly heat pumps , Johnson continues to expand its production capacity in Europe to meet growing demand. The company has strengthened its facilities in Denmark, Turkey and France, and with the DualPAC model it hopes to transform the way heat is managed in low-temperature conditions.
This seawater solution offers a sustainable and efficient alternative to traditional fossil fuel- based methods, representing a model to follow in the transition towards green urban networks throughout Europe.
