From 1 January 2027 the triggering facts remain unchanged: a water-based heating system installed after 30 September 2009 that is not a heat pump and is operated in a building with at least six dwellings or other self-contained units must undergo a heating check and heating optimisation within one year after 15 years have elapsed since installation. Where the system was installed before 1 October 2009, it must be checked and optimised by the end of 30 September 2027. What changed is the content of the check: the former catalogue of four items is dropped. The check now establishes whether the heating system is operated efficiently with regard to its essential settings, components and operating parameters. Optimisation continues to include adjustments to control, temperature and operating management and further operational settings, and advice on additional saving measures, in each case taking account of possible effects on the building fabric and on human health. Identified optimisation measures must be carried out. Further references: Section 60b(1) to (5) as in force from 1 January 2027, Section 108(1), points 10 and 11.

Ab dem 1. Januar 2027 bleiben die auslösenden Tatbestände unverändert: Eine Heizungsanlage mit Wasser als Wärmeträger, die nach dem 30. September 2009 eingebaut oder aufgestellt wurde, keine Wärmepumpe ist und in einem Gebäude mit mindestens sechs Wohnungen oder sonstigen selbständigen Nutzungseinheiten betrieben wird, ist innerhalb eines Jahres nach Ablauf von 15 Jahren nach Einbau oder Aufstellung einer Heizungsprüfung und Heizungsoptimierung zu unterziehen. Wurde die Anlage vor dem 1. Oktober 2009 eingebaut oder aufgestellt, ist sie bis zum Ablauf des 30. September 2027 zu prüfen und zu optimieren. Geändert hat sich der Prüfinhalt: Der bisherige Katalog von vier Prüfpunkten entfällt. Geprüft wird nunmehr, ob die Heizungsanlage hinsichtlich ihrer wesentlichen Einstellungen, Komponenten und Betriebsparameter energieeffizient betrieben wird. Zur Optimierung gehören weiterhin Anpassungen der Regelung, der Temperatur- und Betriebsführung sowie weiterer betrieblicher Einstellungen und Hinweise auf weitergehende Einsparmaßnahmen, jeweils unter Berücksichtigung möglicher Auswirkungen auf die Bausubstanz und die menschliche Gesundheit. Festgestellte Optimierungsmaßnahmen sind durchzuführen. Weitere Fundstellen: § 60b Absätze 1 bis 5 in der ab 1. Januar 2027 geltenden Fassung, § 108 Absatz 1 Nummern 10 und 11.
