. Note that the types of chips produced, for example, by landscape firms for composting and mulching are generally not suitable as a wood biomass fuel.

Wood chips however, can be used in automatically fed stoves and boilers. Automatic wood biomass energy systems, fed with an auger and/or conveyor, use chipped or pelleted wood which must be the correct size for the feed system to handle and so are generally designed to take wood chips at set specifications. Wood chip boilers can be sensitive to size and moisture content.

Wood pellets and briquettes are man made wood products that can be used in place of logs and timbers in traditional fires and modern log boilers. They range in size from a few millimetres in diameter and length to about 12mm (1/2″) in diameter and 50mm (2″) in length. Wood biomass pellets and briquettes are produced by compressing clean waste wood such as sawdust, wood shavings and joinery offcuts in a high pressure pellet mill. No additional materials are used as wood pellets must contain only pure wood.

The advantage of wood pellets is that they are easy to handle and can be used a wide range of semi and fully automatic biomass systems. They are generally stored in hoppers and bins. Wood biomass pellets and briquettes made from MDF (Medium Density Fibreboard), chipboard or other such engineered wood board materials must be burnt in purpose designed incineration equipment due to their high glue and resin content. The source material must be clean and uncontaminated in order to avoid undesirable emissions.

Fully-automated wood fired biomass heating systems are now commonplace around the world. Log-fired boilers and wood pellet-fired stoves such as the are now easily available online providing a clean, green, and convenient wood fuel heating system.

But wood biomass energy heating systems must also consider its associated economic costs and how they compare with the cost of heating from conventional sources of energy, such as fossil fuels and electricity. While wood fuel fired boilers and heating systems are robust and solid items of equipment with in some instances will have a longer life span than typical mass produced gas or oil fired boilers, wood fuel storage and delivery systems can be costly and take up a lot of space.

The size of a biomass boiler room and wood fuel store often necessitates the use of separate rooms or areas within a building whereas a natural gas or oil fired boiler generally fits in a small room (usually the kitchen) that is part of the building being heated.

However, as the costs of fossil fuels such as coal, natural gas and fuel oil continue to rise, the use of a wood fuel heating system will become increasingly attractive if the wood biomass fuel is easily sourced or the price go downs. Another major advantage of wood biomass energy heating systems is that they can achieve if burned efficiently, significant reductions in total emissions of greenhouse gases, principally carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), which are implicated in global climate change.

Once wood fuel was our only source of energy for heating and cooking but has been replaced by coal, oil and natural gas as our primary fuel source over the last two hundred years or so. Our increasing awareness of the environmental damage caused by our continued use of fossil fuels has lead to a growing interest in the use of wood as a sustainable, renewable, low carbon alternative. Today, wood biomass for energy is becoming increasingly more important as an alternative energy source in providing us with a major source of renewable heat energy.

The technology to generate energy from wood fuels is starting to become more developed with virtually limitless possibilities. The economic advantage of wood biomass energy is that wood fuel is less expensive than fossil fuels offering a sustainable and dependable supply from a variety of wood based products.

But the necessity of a larger-sized wood burning boiler, the complexity of automatic filling with augers and belts, slow response to peak heating demands, and the need for ash removal and disposal are some of the disadvantages that must be considered against what at first glance appears to be a cheap fuel source.
