Overview
- Germany’s heat pump market rebounded with a 35% sales increase in the first quarter of 2025 after a dip in 2024.
- Installation costs for water-source heat pumps in single-family homes range widely between €20,000 and €63,000, and nearly half of initial offers omit detailed cost breakdowns.
- Fees for deactivating, decommissioning, or removing gas connections vary by operator from zero up to €6,000, with the average disconnection cost around €1,750.
- Legal experts including Miriam Vollmer note that no clear federal rules define which disconnection costs network operators may pass on to consumers.
- Consumer protection groups and the Bundesverband Wärmepumpe are calling on lawmakers to establish uniform cost-sharing regulations as municipalities prepare mandatory heat plans for 2026 and 2028.
