Our corporate philosophy is clear: We want to make a difference - and actively promote the heating transition. We do not see ourselves as teachers, but as Reliable project partners and employers, who are themselves convinced of the benefits of modern energy technology. This is precisely why we implement sustainable solutions not only for our customers, but also for in your own company consistently. An important milestone is our PV and PVT roof system at the Kaufbeuren site, which was a particular focus in 2025.
