Energy cost, not only mass cost
- ▸Calorific value affects how many tonnes you need for the same heat demand. For reference: sunflower-husk pellets typically 16–18 MJ/kg, wood pellets — 16–19 MJ/kg.
- ▸Compare offers also on approximate cost per useful energy, accounting for boiler efficiency.
Operating cost
- ▸Ash content (2–4% for husk, ≤ 0.7% for wood) affects ash handling, maintenance frequency and downtime risk.
- ▸Moisture, mechanical durability and fines affect combustion stability and storage losses.
Logistics and documents
Packaging, Incoterms, delivery cadence, trial batches and the document package can change total deal cost more than a small difference in price per tonne.
How to compare offers
- ▸Same delivery terms and packaging
- ▸Clear technical parameters and COA availability
- ▸Approximate consumption / energy-cost view
- ▸Maintenance and compatibility risks for the specific boiler
