Wood chip boiler

Local benefits:

Heat water and habitat.

Travellers benefits:

Use a heating system that is efficient and using wood.


The wood chip boiler is an excellent alternative to the gas boiler. Much more environmentally friendly, it is also very economical and amortized quickly. Ideal for heating large areas requiring multiple boilers.

How does it work? How much does it cost?

At “la Ville Heleuc”, its operation simple :

  • Beatrice and Michel installed the boiler in 2004. It has been amortized over 7 years. The installation cost them a bit more than € 20,000.
  • Once a year, the shredder come to cut the wood into pieces. It costs them around € 600. The wood chips are then stored in a shed. (if you do not have pine trees, count € 25 for a cubic meter of wood chips, knowing that it takes, for this configuration, around 100 per year).
  • The boiler, installed a few meters down, works with a system of worm. The only switching operations are filling wood chips when it begins to fail, and empty the ashes once a month.
  • The boiler is connected to the four houses by underground pipes (for the installation, count € 100 per meter). Please note: the loss is very small: about one Celsius degree every 100 meters.

The advantage on gas (ecology aside)

A gas boiler costs about € 1,300. For 4 boilers, there should be 2 tanks of gas per year (approximately € 4,000).
