This system, in spite of its great success, is still relatively unfamiliar to most people.
So let’s take a look at the main features of the latest generation of stoves.
Wooden pellets are made from waste produced by the wood industry, compacted into small cylinders with a diameter between 6 and 8 millimetres and a length of up to 30 mm using pressing techniques.
This fuel is heavier and more compact than wood, thanks to its compression; therefore, when used in equal volumes, pellet combustion produces more heat than the wood products usually employed.
Wooden pellets are considered a renewable energy source, as the trees used to produce them are left to grow steadily and replaced with younger plants the moment they are felled, in a continuous cycle.
As it is a very compact material, it only requires a small amount of storage space.
One cubic metre can hold 650 kg of pellets; this is a tiny area if you consider the bulky containers used to hold liquids and gases.
The most common are semi-automatic stoves, which are switched on by pressing a button and run independently for a period of 15 to 45 hours.
These models are activated by a thermostat, which can be set to suit your requirements and which even allows the heating system to be switched on and off in line with certain time-based requirements.
On a visual level, models can be more modern or more "vintage" in style, but those which create the most welcoming atmosphere have a glass door, allowing you to see the burning fire from outside.
