The industrial group Danfoss and the digitalization subsidiary of the Eon Group, Eon One, have launched a digital heating control system for existing and new buildings.

Danfoss and Eon One are pooling their expertise to establish an integrated solution for intelligent heating control in buildings. The centerpiece is the combination of the cloud-based Leanheat Building software from Danfoss and the Intelligent Heating Control Box (IHC) from Eon One. The target group for the joint solution is primarily housing companies, property managers, investors and operators of heating networks.

According to the two companies, control is automated and based on current weather data, building thermodynamics, consumption patterns and signals from the heating networks. This would enable heating energy savings of up to 30 percent. CO2 emissions could also be reduced. The technology is designed for use in new and existing buildings and, according to information from Eon One, can be installed without structural interventions.

Pilot projects from the second quarter of 2025

The strategic partnership will start with pilot projects in Germany. Further installations at energy suppliers and housing companies are planned from the third quarter of 2025. A market launch in Poland, Sweden and Finland is set to follow by the end of the year, with expansion to other European countries planned for 2026.

The IHC Box continuously records measurement data in the boiler room, such as outside, flow and return temperatures. This data is transmitted to the Leanheat software, which uses AI algorithms to adapt heating curves individually for each building. The software is already being used in over 200,000 residential units, primarily in Northern Europe, and is now to be scaled up to Central European markets, the partners write in their press release.

Building owners can access all relevant monitoring and control functions via a dashboard. If a building is connected to a heating network, it can act as a virtual heat storage facility. This flexibility enables suppliers to operate their grids more efficiently and smooth out peak loads.
