Overview

• Verband Privater Bauherren advises inspecting heating systems during the off-season to identify inefficiencies and decide on component modernization or full replacement.
• Homeowners can choose partial modernization to swap boilers and control units for lower upfront costs but full replacement ensures compliance with current technical standards and enables integration of renewable technologies.
• Pairing heating upgrades with building envelope improvements such as wall, roof and window insulation helps minimize heat loss and amplify efficiency gains.
• Energy consulting services range from free online tools to on-site visits costing about €40 for initial advice and €1,600 to €2,000 for comprehensive renovation roadmaps.
• Only consultants listed on Energie-Effizienz-Experten.de are eligible for BEG subsidies and in-person assessments prevent oversights common in photo-based evaluations.
