Germany mandates hydraulic balancing for home heating under new building energy law

Germany's Building Energy Act (GEG) now requires mandatory heating system checks and hydraulic balancing for single- and two-family homes. The measure aims to improve heat distribution efficiency, lower heating costs, and cut overall energy consumption. The regulation aligns with the federal Energy Efficiency Act's target to reduce final energy use by 27 % by 2030 compared with 2008 levels, with a longer‑term goal of a 45 % reduction by 2045.

Implementation will involve precise measurement and adjustment of flow rates and pressure in heating circuits to match actual demand, especially in older buildings with varied pipe networks and control systems. Industry players are adapting by offering data‑driven monitoring and control solutions, while manufacturers such as Stiebel Eltron have introduced new heat‑pump models to meet the stricter standards.
