Three phases, one contact — from first visit to delivery.
1. Technical audit
On-site assessment, heat-load calculation, building energy profile, options with CAPEX and OPEX projections — all in a single document.
2. Proposal ready for general assembly
Clear document for the general assembly: timeline, cost per apartment, energy savings and subsidy eligibility. We attend the meeting to explain.
3. Phased execution
Hot water and heating remain available during switchover — we plan around residents, not against them. Syndic receives a weekly progress update.
Options we typically recommend
We compare the two main routes based on your building envelope, age and budget.
Cascade condensing boilers
2 to 4 modular gas boilers sized for demand, with a single hydraulic header. 95-98% efficiency, redundancy if one unit fails. Brands picked to suit: Buderus, Bosch and Vaillant.
- Efficiency 95-98% (HHV)
- Redundancy on failure
- Compact: usually fits existing boiler-room
Hybrid: heat pump + peak-load boiler
Air/water or geothermal heat pump covers 70-80% of annual demand, existing or new gas boiler covers peak cold. Big CO₂ cut, minimal envelope work.
- 70-80% of annual demand on the heat pump
- Subsidies for collective heat pumps in 2026
- Compatible with existing radiators
