High-Quality Fuel Easily and Inexpensively

Pellets are domestic, renewable bioenergy in a compact and efficient form. It is dry, dustless, odourless, of uniform quality, and manageable fuel. The heating value is excellent.

At its best, pellet heating is as easy as the old school oil heating. The price of pellet heating is about half of the price of oil heating. Read more about pellet’s energy content here.

Wood pellets are mainly prepared of industrial by-products such as wood shavings, grinding dust or saw dust. The raw material is hydraulically compressed into a grain, and wood’s natural binding, ligning, holds the pellet together. Pellet is dry wood, with the moisture content of 10 % max. This means that it does not freeze or go mouldy.

Utilisation

Pellet boiler with an integrated pellet burner built in the place of an old oil boiler. Pellet boiler fits into a very small space, and is a worthy and affordable alternative for oil heating.

Pellet is a truly multi-use fuel, which can be utilised in central heating in a pellet burner or a stoker burner. The most common pellet heating system in detached houses is central heating using water circulation with a pellet burner and boiler.Pellet can be burned in systems with bottom unloader or manual system, as it is or mixed with other fuels. For example, during freeze-up wood chips might be moist. Mixing in some pellets in gives the fuel some extra energy.

Simple measures can affordably make you a user of bioenergy. A good idea is to preserve and transform the old central heating boilers so that they are suitable for bio heating. This is done so, that the old burner is replaced with a pellet burner. A pellet burner with boiler fits into a very small space.

A silo for storing the pellets can be built of an old oil drum or a wheelie bin. The silo can be filled from a large pellet sack in every few weeks depending on the consumption. Read more about how to store pellets here.

If pellets are used in central heating and they are burned in a pellet burner, a special silo must be designed and built for storing the pellets. The fuel is automatically rationed with a screw conveyor from the silo into the burner.

Pellet burner can be installed into most wood boilers and into some of the old oil boilers. Often old oil boilers have a rather small water capacity, which means that a hot-water tank might be needed to ensure the sufficiency of hot service water.
