Cost: pellet or biomass boiler
Compare boiler, storage, feeding and connections together. Equipment-only offers cannot be compared with installations including storage and adaptations. Existing emitter compatibility needs assessment.
Editorial update on 18 September 2026
Break down plant room and storage
Separate boiler, storage, fuel feeding, connections and room works. Specify accessories, protection, access and commissioning. Price any tank treatment separately.
Examine operating expenses
Request consumption estimates with assumptions, then dated tariffs and delivery charges. Add maintenance and checks by scope. Neither stable fuel prices nor savings against another energy source are guaranteed.
Check the grant scheme
Klimabonus lists and conditions depend on equipment and project. Check the model, requirements, dates and evidence. Neither the word biomass nor removal of an oil boiler alone guarantees a grant or bonus.

Frequently asked questions
Will storage last a whole season?
Check usable capacity, consumption and delivery conditions. No seasonal autonomy is guaranteed without these data.
Can every radiator be retained?
Have suitability assessed. Choosing biomass alone does not establish compatibility.
Does biomass automatically mean Klimabonus eligibility?
No. Check the exact category, model and scheme conditions on Guichet before counting a grant.
