More Heat From Your Stove
This short article is aimed at new stove owners and explains how to get more heat from your stove and use less fuel as a result.
It goes without saying that the choice of fuel is critical. If you’re using logs which have a high moisture content then you’re never going to manage to get your stove up to temperature. What is a high moisture content? – 20% or over! Freshly felled wood can have a moisture content of over 50% which means literally that every log is half water. All you’re going to produce is steam. Assuming you’re using good quality fuel – and our kiln dried mixed hardwoods are just about the best you can buy, then there are a few simple do’s and dont’s to get more heat from your stove.
The most common error stove owners make is to overfire their stove – air controls fully open and a roaring log fire as a result. It looks great but most of the heat generated is being whisked up your chimney. You risk damaging your stove and will go through fuel at an alarming rate and assuming you’ve invested in good quality fuel, there really is no need to have a gale whisting through it all.
We would recommend investing a few pounds in a magnetic stove thermometer which is placed onto the stove flue. Adjust the air controls so that the pointer rests in the green zone – usually around 480C. This is the temperature at which both your stove and fuel will operate at maximum efficiency and greatest economy AND be less polluting, ensuring that more heat is radiated into the room and not forced up the chimney giving you more heat from your stove.
To give an example, our stove, an 8kw Hunter Herald, operates with the bottom air vent fully closed and the top air vent only just cracked open or very often even shut if it is a windy evening. Each stove is individual so you may have to experiment to get the most efficient burn and more heat from your stove.
Remember too if you are looking for more heat from your stove and you own a multifuel stove, close the grate completely – logs burn best on a bed of ash and do not require air flow from below.
