The wood heating has already made comeback for a few years now. This is not surprising given that it is an economical and ecological solution. High-performance wood-burning heating systems are available in a wide range of models, from stoves to boilers. Such is the case with the wood-fired boiler.
Wood: a fuel with many qualities
The firewood is a very advantageous fuel since its use and its acquisition will pose you no problem. In addition to its natural and ecological appearance, it can achieve significant savings. Indeed, it costs less than any other energy source such as gas, fuel oil or electricity. In addition, it can be in various forms: wood-logs, wood pellets, forest chips and shredded wood.
How does a wood boiler work?
The operating principle of a wood-fired boiler remains the same, regardless of the fuel used. Thus, burning wood produces energy that is used to produce hot water for housing purposes. On the one hand, there is the hot water of your heating network that feeds the radiators of your home or your floor heating. On the other hand, it contributes to the production of domestic hot water for the needs of the bathroom and the kitchen.

What are the different types of wood boiler?
There are three models of wood-fired boilers: the wood-log boiler, the pellet boiler and the shredded wood boiler Australia.
In the first place, the log boiler is the most affordable model. Small volume, it is very easy to use. For its performance, it can reach up to 85%.
Secondly, the pellet boiler is the most efficient model with a thermal efficiency between 85 and 95%. Moreover, it is very quiet equipment that offers a comfort of use of the most pleasant. This installation also has a very long autonomy which can be up to several months. Like the pellet stove, it is equipped with a tank that ensures its automatic feeding.
Finally, the boiler with shredded wood or with wood chips also offers a very exceptional yield which can be between 75 and 90%. Like the pellet boiler, it incorporates a silo for a better autonomy.
Some information about choosing firewood
The performance of your heating appliance depends very much on the characteristics of the fuel you are using. Use the following tips to choose your wood.
Wood species are classified into two major families according to their density:

  • Hardwoods (oak, beech, ash, chestnut, charm, walnut, fruit trees, etc.)
  • Coniferous and softwoods (spruce, fir, pine, larch, poplar, willow, etc.)

Hardwood hardwoods are the most popular for domestic heating, with the exception of the chestnut tree which bursts on burning. Soft and resinous hardwoods burn faster! If they are poorly stored, they degrade rapidly. Softwoods are nevertheless appreciated for their rapid rise in temperature.
Wet wood burning is not recommended for various reasons:

  • Environmental issues: the burning of “green” wood releases many pollutants;
  • Economic: a damp wood provides about half as much energy as a dried wood;
  • Practical: high-performance appliances will not reach their rated power with fresh wood. The material will get dirty faster and may deteriorate.


They are designed for burning wood and charcoal on the principle of gasification generator by an exhauster fan sucking the flue gases of the boiler.
The boiler body is manufactured as a welded steel plate quality a thickness of 6 to 3 mm piece. It consists of two chambers situated one above the other, the top serves as fuel tank, as the lower combustion chamber and ash pan. Among them is a new rotary screen is protected with patent, allowing perfect coal gasification, either separately or in common and easy ash removal. In the rear of the body of the boiler there is a vertical flue gas channel equipped with a valve on top. The top of the flue gas channel has a shot nozzle to connect with fireplace.
Wood Gasification Boilers are the modern version of the wood burning stove that burns the wood completely and leave no smoke, ash or creosote. The boiler saves up to 70% of your energy bills when installing on a plinth, radiant or forced air heating system.
Advantages of gasification boilers

  • Possibility of burning large pieces of wood
  • Possibility of burning coal and wood separately or together
  • Great fuel tank -time long combustion
  • High efficiency of 81 to 87% depending on the type – the primary and secondary air is preheated to high temperatures
  • ecological combustion
  • exhauster fan – dust collection ash, boiler room smokeless
  • Cooling loop against overheating – without the risk of damaging the boiler

Since the time when humans used to live in caves, wood was the major source of fire or rather heat. People would turn to wood for warmth, cooking, and safety. As, we started getting more advanced from we started using different ways to provide heat but by using the same fuel which was wood.


Wood-fired stove was the centerpiece of many kitchens. This was before the introduction of other fossil fuels which were not known to us, can be used for heating as well. And, also before the concept of central heating was ever there.


Then with modern advancements there were central heating systems which are now called as hydronic boilers, which use water as a source of providing heat throughout the house through pipes. But, also with the advancement of other heating options and other fuels available. There was a slight decline in the industry of wood hydronic boilers.


But with the price increase in the prices of oil, gasoline and other fuels there was again a steady rise in the demand of wood fired hydronic boilers, there were a few drawbacks which they had some of them were:-


  • There was a requirement for their heat exchanger brushed to be clean every 1-2 weeks during the heating season
  • Emptying of ash bins occasionally.

However, the modernization of wood fired hydronic boilers not only solved the above problems but also has improved the way heating can be done effectively, at a low cost and also in an eco-friendly manner.


    • Modern boilers come equipped with automatic cleaners for the heat exchanger so you do not normally have to do it.
    • They offer versatility if you happen to run low on the wood stock, you can always use it combine with other sources of fuel for that time being.
    • Concerns over the amount of pollution created by these boilers, there has been an environment friendly approach in which wood-based biomass heating systems are used which employ wood pellets to be used for heating and hence wood being a carbon neutral fuel, does not increase the amount of carbon dioxide and hence maintaining the level of emission.
    • Not only is it environment friendly but also is a cost-effective option. The facts will astonish you.
    • Cost of heat produced by burning wood pellets is about half that of heat produced by oil or any other fuel.
    • Modern-day boilers have web accessible controls that can help the owner run the boiler as well as peripheral devices, and hence keep a check on the temperature. Also, advancements have also made it possible to turn on the heating and turn it off whenever and wherever you need it.


All, of these advances surely give hydronic boilers the edge over other heating systems.
