APARTMENT BUILDINGS

Collective boiler-room renovation

Aging boiler-room in your co-ownership? We plan and execute phased replacement, with minimal downtime and clear cost-sharing for residents.

Our approach for co-ownerships

On-site assessment, heat-load calculation, building energy profile, options with CAPEX and OPEX projections.

Clear document for the general assembly: timeline, cost per apartment, energy savings, subsidy eligibility.

Hot water and heating remain available during switchover — we plan around residents, not against them.

2-4 modular Buderus gas boilers sized for demand, with a single hydraulic header. 95-98% efficiency, redundancy if one unit fails.

Air/water or geothermal HP covers 70-80% of annual demand, existing gas boiler covers cold peaks. Big CO₂ cut, minimal envelope work.

Individual metering per apartment can be added on top of any option — fair cost-sharing based on actual consumption.
