Biofuel

Bio energy is the most ancient form of energy in the world. By bio energy, one refers to biologically dissolvable materials such as wood, straw, grass, waste, manure, alcohols and bio diesel (rape seed oil). These energy sources are regarded as renewable as the CO2 absorbed as the trees grow cancels out the emissions when the wood is burned. Most of us are familiar with firewood and its heating capabilities, but new ways of using wood can make such heating more effective and controllable. When using for example a pellets burner, pellets are filled in a separate container and automatically fed to the burner when necessary.

Environmental impacts


An important advantage with bio energy is that it is neutral when it comes to climate gases.

 

The carbon dioxide which is created when burned has previously been absorbed by the plant and thus, it does not represent a net emission as long as the trees are replanted.

Pellets


Pellets can be used in boilers which are connected to a central heating installation. The installation of a pellet boiler is a large investment, but as opposed to for example a heat pump the pellet boiler can cover the entire need for heating, even during the coldest periods. There are currently pellet boilers with automatic start/stop, automatic sweeping of the boilers standing smoke tube and automatic ash removal. These boilers, combined with vacuum feeding (vacuum cleaner principle) of pellets from a larger, dust proof silo provide the most comfortable heating with pellets.

 

Compared to installing a pellets burner in an existing oil boiler, these solutions are rather expensive, but by choosing this solution everything will be automated and you will experience a far better comfort. Such a fully automated installation requires considerably less work, but a pellets boiler still requires quite a lot in terms of maintenance. Normal pellets boilers require attendance on a weekly basis. Regardless of the solution, a pellets boiler will require considerably more service than oil, gas and electric boilers. Pellets should be stored in non-flammable containers. And since pellets is a fairly new fuel it might it might be hard to get pellets and pellets boilers in some parts of the country due to limited availability.
