Industrial process in Luxembourg: how to secure your renewable heat supply
Industrial biomass heat in Luxembourg: APS-phase methodology to secure pellet supply and maximise Klimabonus. Practical guide for architects.
Updated 22 August 2026·4 min read
Why biomass for an industrial or tertiary site?
A 70+ kW pellet boiler can supply an industrial or tertiary site with stable heat.
Unlike gas or oil, biomass is local, renewable, and less exposed to global price swings.
- Local, renewable energy source.
- Price stability over 10 to 15 years.
- Reduced carbon footprint for the site.
- Compatible with EN 303-5 standard.
How to secure pellet supply?
For a continuously running installation, supply security is critical.
Four concrete levers to integrate from APS onwards:
- ENplus-certified pellets with a delivery contract.
- Buffer tank to smooth load variations.
- On-site storage covering 3 to 6 months of consumption.
- EcoDesign 2015/1189 compliance from the design phase.
Klimabonus 2026 and communal subsidies
Klimabonus 2026 is active and applies to wood pellet boilers.
For a heat network: up to €6,000, capped at €24,000.
- Bonus +15% with buffer tank.
- Bonus €1,000 flat with solar thermal.
- Single-family home: up to €8,000 (€4,000 without replacement).
- Communal subsidies: variable, check via Klima-Agence simulator.
Method from APS: four key points
From the design phase, architects and project owners should:
These four points save time and secure the budget.
- Calculate the site's exact heat demand.
- Plan the pellet silo and feeding system.
- Verify EcoDesign emission values.
- Integrate Klimabonus and communal subsidies into the budget.
