Heat Pump Boom in Germany Meets Hurdles From Installation Cost Gaps and Gas Exit Fees

Consumer advocates want uniform regulations to address opaque gas disconnection fees fueled by volatile heat pump prices

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.
