Heat pumps in Leipzig
Heat pumps in Leipzig at a glance
The city council adopted the municipal heat plan on 28 May 2026, before the federal deadline of 30 June 2026. The city used the "Wärme für Leipzig" portal and the "Leipziger Wärmewende-Kompass" for public participation. From 1 July 2026, only heating systems with at least 65 per cent renewable energy may be installed in Leipzig because Leipzig exceeds the 100.000-resident threshold.
Saxony does not offer direct grant funding for heat pumps, but rather reduced-interest loans through SAB. Owners in Leipzig combine KfW 458 with SAB programmes.
