Choosing between a gas boiler and a biomass boiler is one of the most important decisions for industrial steam users. The biggest concern is simple: which one is cheaper per ton of steam?
This guide breaks down the real cost difference and provides a free calculator to estimate your boiler operating cost instantly.
Quick Comparison: Gas vs Biomass Boiler Cost
| Facteur | Chaudière à Gaz | Chaudière à biomasse |
|---|---|---|
| Coût du carburant | Haut (depends on gas price) | Faible (cheap biomass fuel) |
| Efficacité | 90% – 98% | 75% – 88% |
| Labor Cost | Faible (automatic) | Plus haut (fuel handling) |
| Entretien | Faible | Moyen à élevé |
| Overall Cost per Ton Steam | Moyen à élevé | Faible à moyen |
Gas Boiler Cost per Ton of Steam
The cost of a gas boiler mainly depends on gas price and efficiency.
- Natural gas price: $8 – $15 / MMBtu
- Steam cost: $12 – $25 per ton
Avantages:
- Fully automatic operation
- Clean combustion (low emissions)
- Stable performance
Inconvénients:
- Fuel cost fluctuates heavily
- Higher long-term operating cost
Biomass Boiler Cost per Ton of Steam
Biomass boilers use fuels like copeaux de bois, balle de riz, or palm shell, which are much cheaper.
- Biomass fuel cost: $30 – $80 per ton
- Steam cost: $6 – $15 per ton
Avantages:
- Faible coût du carburant
- Renewable energy source
- Suitable for high steam demand
Inconvénients:
- Requires fuel storage space
- Travail plus élevé & entretien
- Lower efficiency than gas
Which One Is Cheaper?
Short answer:
- If fuel is cheap → Biomass boiler wins
- If automation & cleanliness matter → Gas boiler wins
For most developing regions (Africa, Asie du Sud-Est), chaudières à biomasse can reduce costs by 30%–60%.

FAQ
Is biomass cheaper than gas?
Oui, in most cases biomass is significantly cheaper, especially in regions with abundant agricultural waste.
Fuel handling, stockage, and labor are the main hidden costs.
Which boiler has lower emissions?
Gas boilers are cleaner, but biomass is considered carbon-neutral.
Conclusion
Gas and biomass boilers each have their advantages. If your goal is faible coût d'exploitation, biomass is the better option. If you need clean, automated operation, gas is the ideal choice.
