An environmentally friendly appliance which provides both heat and hot water is the wood boiler. It is an alternative choice of heating compared to more conventional sources of heat, but is still able to provide central heating throughout a whole building.
Wood burning boilers are large units that are installed in either an outbuilding or utility room, and operate by gasification; heating wood to wood gas to produce an efficient source of heat.
How Do Wood Boilers Work?
The wood gasification boiler, as it is otherwise known, incorporates a firebox which is filled with logs. The logs are then burned, producing low level emissions, and the heat from the wood can be stored in a hot water tank until needed, but is most often connected directly to the central heating and hot water systems.
Inbuilt programmers allow the owner to decide when and how the home or business place is heated, which automatically draws heat out of the wood burning boiler.
Wood Pellet Boilers
Not just logs, wood boilers burn many types of wood, a popular one being wood pellets. Wood pellet boilers use what is regarded as a carbon neutral energy source as they are made of 100% natural wood. Shavings and sawdust are compressed under high pressure, and pressed into small cylindrical rolls. This not only results in the production of a clean, convenient fuel, but the wood pellet boiler also utilises fuel that is environmentally friendly.
Wood Chip Boilers
Wood chip boilers are similar to wood pellet variations, though this particular wood fuel source may be more cost effective. A wood chip boiler is an ideal option for those with access to waste wood as less money is spent when burning your own waste. As wood chips do not flow as easily as wood pellets, these boilers use agitator mechanisms, which stir the chips, otherwise they would solidify and cause blockages.
Wood Burning Stoves with Back Boiler
Not solely for heating one room, wood burning stoves with back boiler features can be used to supplement existing central heating systems even though the stove is only fitted in one room. The wood burning stove with back boiler feature also supplies hot water to the building by burning wood to create fuel in a separate boiler at the back of the firebox. The majority of heat produced from the stove feeds back into the back boiler which produces heat and hot water to the whole building, in addition to the stove itself.
Wood burners with back boilers are generally made from cast iron to maintain a traditional style, but using advanced technology to operate them.
Benefits of Wood Boilers
Wood boilers are robust, reliable, and very efficient appliances for burning wood with low level emissions. Their large combustion chambers accommodate more fuel than other sources of heat, decreasing the number of times wood has to be added, another benefit of these boilers.
Wood burning boilers are ideal for those who have sufficient room to store the large capacity boilers and firewood, particularly people with access to woodland or cheap wood. Though, as these boilers are large appliances, they would also be suitable for business use in industrial settings or farming and rural locations.
