A multi-fuel stove makes a house a home, especially in the wintertime. When you have this type of heating appliance installed, you can enjoy a warmer and cosier environment as well as increased flexibility. Besides burning wood, a multi-fuel stove can also burn peat or coal. Therefore, you can choose from among many fuel options, especially if you experience a power outage. There is a fantastic article you can read on stoves.
A Warmer and More Hygienic Indoor Environment
When you can heat your home with solid fuel, you can do so for an extended period. What’s more, the heat from the stove will extend to the surrounding rooms. Regardless of the type of fuel you use, you do not need to worry about condensation appearing. Condensation can lead to the formation of mould. Therefore, a multi-fuel stove promotes a warmer and more hygienic indoor environment.
Two Grate Designs
Multi-fuel stoves in Northamptonshire work because they feature a grate. This grate is located at the bottom of the appliance. Usually, the stoves feature one of two grate designs:
- Central grates feature an ash pan beneath them
- Raised grates display moving bars
Both of the above grates are easy to maintain and clean. As the fuel is burning, the deposits of ash collect beneath the grate. Whether a stove burns wood or various types of fuel, air must be introduced into the stove for combustion purposes.
The Combustion Process
A multi-fuel stove features two inlets for the circulation of air. One inlet is located beneath the stove, and the other one is situated close to the top of the stove. When an inlet is open, the air ignites the embers, thereby causing the hydrocarbon particles and gases to combust.
Burn Each Fuel Separately
If you elect to buy a multi-fuel stove, you have to keep in mind that wood and coal burn differently. Therefore, you do not want to burn both these products together. Even though a stove may be classified as a multi-fuel stove, you should burn each fuel separately.
For example, you should not burn wood on a bed of coal and open the top air intake unit. The coal will produce high levels of CO2 and carbon monoxide and will suppress the wood gases. These gases, which usually mix with oxygen, will travel up a chimney and deposit creosote – a flammable material.
If oxygen levels and combustion temperatures are too low, the latter stage of combustion will not take place. During this last phase, the soot particles from carbon should burn. If they do not, they will exit the chimney in the form of fine dust and endanger the quality of the air.
Alternatively, if coal is burned on top of the wood, the burn will be incomplete. Also, when wood is burned, it produces a good deal of ash, which will block the grate, thereby reducing the amount of available oxygen. If the coal is smokeless, a high level of sulphurous materials will be disbursed. These materials are highly corrosive and can easily damage the steel liners of the stove.
