Pellet boilers: sustainability and long-term savings

• ✅ Renewable and more sustainable fuel.
• ✅ More stable pellet price and less dependent on oil.
• ✅ Significant reduction in CO₂ emissions.
• ✅ Automatic feeding systems with silos that provide autonomy.

• ❌ They require a large space to store the pellets.
• ❌ Higher initial investment compared to an oil boiler.
• ❌ Require more frequent cleaning and maintenance (ash and soot).
• ❌ Less convenience in systems without automatic loading.
• ❌ Lower energy density: a larger volume of fuel is needed for the same output.

Diesel boilers: power and immediate comfort

• ✅ Simple installation, especially when replacing old boilers.
• ✅ High power and performance, even in large homes.
• ✅ High autonomy thanks to large-capacity diesel tanks.
• ✅ Less maintenance and cleaning than a biomass boiler.
• ✅ Modern condensing versions with savings of up to 20% in consumption.

• ❌ The price of diesel fluctuates and depends on the oil market.
• ❌ Greater environmental impact compared to biomass.
• ❌ Need for space for the fuel tank.
• ❌ Increasingly strict environmental regulations in some countries.

Which one to choose this winter?

• If you are looking for sustainability and also have space to store pellets, biomass is your option.
• If you prioritize convenience, power, and quick installation, especially in rural areas or second homes, the oil boiler is the best choice.
