I am not getting enough heat from my multi fuel stoves

Most people. thankfully do get enough heat from their wood burning stoves. It is rare for this to be an issue however, there are a few common and easily sortable causes which we have come across over the years.

Damp fuel does not give a great deal of heat. It is calorific value of the fuel used in the wood burning stoves or multi fuel stoves which gives the heat. Damp wood creates steam. Logs should always be seasoned (air-dried) for at least a year before being burned. Although bought in wood fuel is always sold as dry and seasoned we have found this sometimes not to be the case. if your wood is damp, or green wood, then it will require to be put away for a while to season or dry for longer. Persevering with damp fuel is a waste of time and money. Look on it as an assett for later and source drier wood in the meantime. In saying this there are some types of wood which simply burn badly, ie have a very low calorific value. You may wish to refer to our guide"What do different woods do."

Another issue to give consideration to if not warm enough is that heated air may be unable to circulate if the woodburner or multi fuel stoves installation has been too tight into the fireplace. It may be that to move the logburner forward in your hearth, by rear venting using either one 90 degree bend or two 45 degree bends which create a larger 90 L bend, onto the stoves rear outlet, between the logburners rear exit and stove flue pipe, therefore, pushing the stove forward into your room allowing for more airflow and preventing heat loss up your chimney, may solve this.

Heat loss up a chimney can also be a cause. Again the solutions are simple. Rear venting your woodburner as decribed in the previous paragraph is one solution. A metallic register plate with a reflective surface blocking the chimney breast area is another solution. The register plate in this case should be made from reflective steel or zinc acting both as a draught excluder, as any register plate does and also a reflective surface for reflecting heat downwards.

Heat loss in chimneys and vaulted ceilings are caused by heat rising. In our office at Country Kiln our ceiling is vaulted, 4.5 meters high. We have installed an eco fan on top of the wood burning stove and multi fuel stove that we use to heat our office. This prevents heat loss, instead of the heat rising to the apex of the vault, it is pushed by the eco fan forward and thereafter circulated around the room.

We use this same method in our inglenook fireplace as heat tends to be retained. We place the fan on top of the multi fuel stove to project the heat out the fireplace using air circulation from the eco fan.

In deepest winter we top up our wood burning with coal, using wood and coal combined to benefit from the use of Country Kiln as multi fuel stoves.

A raised hearth, i.e. the multi fuel stoves being put on a hearth raised up to several feet in height would also detract from heating the core base of your room, simply because heat rises.
