WHO WE ARE
District heating in Europe is shifting from fossil-fuelled boilers to systems that electrify heat supply, integrate multiple sources, and store energy across seasons. The technologies to solve this already exist. The rarer skill is making it all work together inside a network that’s already running. That is what we work on.
We help utilities and municipalities decarbonise their district heating networks — without losing the reliability or affordability customers expect. Heat should be available when it is needed, integrated from any source, and delivered without waste.
We design and deliver thermal systems that capture heat from any available source, store it across seasons, and put it to work where the network needs it. From large-scale heat pumps and pit thermal energy storage with the patented floating lid to multi-source integration, every project is engineered to the network’s actual conditions.
The company used to be the Low Temperature division of Aalborg CSP. In 2026, the work continues as aalborg hc systems, an independent company within the Alois Müller Group. The corporate structure is new. The team and the engineering approach are not. Since 1988, our work has stood behind district heating networks running across Europe.

OUR IMPACT
2026
The Alois Müller Group acquires the low temperature division of Aalborg CSP. The work continues as Aalborg Heating & Cooling Systems, an independent company within the Alois Müller Group.
2020
The patented PTES lid technology is acquired. Lid solutions delivered to Marstal, Høje Taastrup, and other large-scale European seasonal storage installations.
2018
Increasingly, large-scale heat pump systems enter the project portfolio. Projects delivered range from 1 to 18 MW, working with sources from wastewater and geothermal to ambient air.
2016
Flat panel solar district heating projects begin in Denmark (Solrød, Smørum, Halskov, and others) followed by the first German project at Stadtwerke Sondershausen.
2014
Delivery of first-of-their-kind hybrid solar systems in Denmark: Brønderslev (CSP combined with biomass-ORC) and Tårs (CSP combined with flat-panel collectors).
2011
Strategic focus to district heating under the Aalborg CSP name. The Thisted CSP plant is commissioned, Denmark’s first concentrated solar power installation built for a district heating network.
1988
Company is formed with focus on thermal systems in the city of Aalborg, traditionally known for world-class boiler development.
