However, molten wood for heating winter is increasingly used, even for heating water throughout the year. The fires are becoming increasingly closed, clean and efficient, like the ones below and the economy. Boilers that are installed outside the house are also increased.
Three molds firewood is used. Automated boilers are fed with a splinter and/or pellet. They feed by hand and most firewood fires. Alternative fuels are also being extended to wood, such as the bones of the fruit: cherry (Prunus avium), olives (Olea europaea), eggplant (Prunus armeniaca), peach (Prunus persica)... In addition to the bones of the fruit, the husks are very good fuels: hazel (Corylus pinavellana), walnut tree. To collect the latter we will have to grease the cascers. For wood, woodcutter and aizkolaris working in wood production shall be multiplied. Prices for these substances have recently been increasing steadily. We can start looking at the mountain and the forest differently!
Ash is the main residue generated by burning bones, skin and wood. The ash will not heat us up, but it will stimulate life on earth. Its main component is calcium, as well as lime, which can replace its work. It also contains other foods: potassium, phosphorus, magnesium… They are all good for soil fertilization.
A little seasonal work to return the sand from the wood to the ground: at this time we are planting onion (Allium cepa) and if we wet the roots in a light paste prepared with ash and water, the contact surface between the roots and the soil increases and the small plantations will stick more easily. Then the ash feeds the onion. And us.
