Property owners will naturally want to know what these changes mean for their own modernisation plans and whether they are affected at all. To help you plan with confidence, we take a closer look at the new noise regulations coming into effect in 2026 and which output ranges are affected.From 1 January 2026, a heat pump will only qualify for grants if its sound power level is ten decibels below the applicable EU limit. This is double the five-decibel margin previously required in Germany. The requirements are therefore becoming significantly stricter, even if the numerical change may initially seem small.
However, the stricter noise regulations were not introduced at short notice; they were announced well in advance. Manufacturers were therefore able to adapt their product development, systematically reduce noise levels and plan new models accordingly. In practice, this means that, across all relevant output ranges, virtually all heat pumps available today qualify for grants. Fans, casing designs and insulation concepts have been adapted so that the units operate not only more efficiently, but also much more quietly.What should you bear in mind now?
For property owners, the most important thing is not to be unsettled by the new limits, as has happened all too often in recent years. If you choose a current heat pump model from the established output ranges, it will generally also meet the requirements that apply from 2026. As the changes relate solely to grant eligibility, existing systems are not affected.What the new rules mean for us
For every project, we always consider both the technical requirements and the conditions on site. We select units that already reliably meet the future noise requirements. Even without the new limits, our aim is to provide you with a system that offers maximum comfort, which naturally includes a comfortable noise level for you and those around you.With Archea New Energy, you can therefore be confident that you are in safe hands!
