Oakfire and Greenheart Workshop Stoves
The Oakfire and Greenheart workshop stoves are very different stoves, both in the way they work and how they are made. It is important to choose the stove that suits your situation, the type of fuel you plan to burn and how you plan to use it.
The Greenheart stoves are a very competitively priced stove that will allow you to heat a workshop for the minimum cost. They are a much lighter construction than the Oakfire stoves and rely on their shape to give them their strength. A cylinder is a sturdy shape and resistant to distortion. However if it is over-fired, and the body is allowed to get red hot, then it will of course distort and the stove will be damaged.
Oakfire stoves have a much bigger capacity and are made of thicker steel. This gives them the ability to take higher temperatures but, just like a Greenheart stove, if the body is allowed to get red hot then it will distort.
The fuel used in joinery shops is often kiln dried timber and shavings and it will burn a great deal hotter than domestic firewood, which will have a much higher moisture content. Normal firewood will have a moisture content of around 25% - 30%, kiln dried joinery timber will be closer to 12%. Put 12% timber into shavings and you have 'rocket fuel'. For that reason a careful eye must be kept on the stove to ensure that it is turned down once the firebox has come up to its working temperature. Failure to do so can result in distortion to the body of the stove.
If you are burning shavings then you must mix in sawdust or the stove is liable to burn too hot. We also strongly advise the use of a flue damper if you intend to burn shavings.
Do not let the stove glow red hot or you will damage it - a stove is a heater which does need some attention - you should not simply fill it up, turn it up full and then walk away without keeping an eye on it. If the fire in a workshop stove is properly regulated then the stove will last for years and years. An over-fired stove on the other hand can distort the body and will burn out the air-tube.
So if you plan to largely burn sawdust, some offcuts and the occasional shavings (mixed with sawdust) then the Greenheart stove will give you many years of service. If, however, your workshop produces a lot of shavings then we would advise going for an Oakfire stove. And if you plan to burn shavings then definitely fit a flue damper and always mix sawdust with the shavings to slow down the burn rate. Shavings burnt on their own, without adequately restricting the air supply, can over-fire a stove.
