Wood pellet fuel is most common in biomass boilers. It is estimated that 1 litre of diesel is equivalent in calorific value to 2 kg of pellets. A kilo of pellets is approximately 0.23 ct / € compared to 0.85 ct / € heating gasoil (diesel prices see here.) Moreover, the cost of pellets is more stable than fossil fuel by not trading in international markets subject to financial speculation.

Certain providers guarantee that the price of pellets will never exceed the CPI + 1% while maintaining the price at a certain percentage below the price of oil.

Pellet quality

When choosing biomass as an energy source we have to evaluate several key aspects, including the efficiency and reliability of machine and fuel use. For us, a first class boiler is worth nothing if the pellet lacks quality.

Din Plus certification ensures optimum pellet and reliability. However, there are many distributors that sell pellets without this certification, and this does not necessarily mean that their material is of inferior or low quality.

We have done this review because biomass is a source of energy that is growing very fast, thus pellets are emerging that offer a quality that doesn’t exactly exist.  By contrast, Spain has an excellent raw material to produce pellets and we do not have to be wary, just aware of what we’re buying.

Here is a map with some distributors spread throughout the peninsula provided by the Spanish Assessment of Biomass Energy. As you can see, some dealers offer Din Plus certification and others do not, without this being a problem for sale. See map
