wood
When the eco-village first started wood was a popular fuel, as it was relatively cheap, easily obtainable and in effect co2 neutral. Many of the older houses are therefore heated by wood burners of mass ovens. Today there is an increased focus on particle pollution, and most new houses are build with an other heating source.
Most of the houses that are heated by wood burning have a mass oven, which is a big, heavy brick or stone oven in the middle of the house, it is fired once a day to very high degrees, which gives a cleaner combustion and less pollution. The pricks or stone then absorbs the heat and slowly releases it during the day, thus keeping the house warm. Furthermore many mass ovens have build in oven space for baking bread or other cooking.
The building Under solen, which contains our bakery, shop and cafe, is heated by excess heat from the baking oven, which runs on rapeseed oil.
