Pellet stoves

What do these innovative stoves consist of? It is one of the most efficient heating systems that we can find today. These stoves work by generating heat through the combustion of small wood pellets, also considered as biomass. This ignition occurs in a closed chamber emitting the heat it creates to the entire space in which it is located. The result is a warm and pleasant atmosphere, which leaves behind the winter cold in our home.

Thanks to the high calorific value of pellets, not only is an environmentally friendly system achieved , but also a high performance is obtained.

What do pellets consist of?

These are nothing more than a type of fuel, which is also ecological and economical. It has one of the lowest emission levels that currently exist, and they are also very practical. Although to be sure of all these characteristics, the pellet must be properly certified.

Today, the purchase and use of pellets is fully approved and standardized. Buying them in a standard way, taking into account a series of requirements allows, in turn, to compare this product with others in equivalent conditions.

Some characteristics of pellets to compare them with other fuels are:

  • 100% composed of untreated wood
  • It has a calorific value of 4.8 kWh per kilogram
  • Its length varies from 6 to 10 millimetres

Pellet stove operation

Its operation is purely automatic, so the risk of suffering any kind of burns is non-existent: it is totally safe.

When the stove is lit, the electrical resistance it has becomes incandescent. After this, some pellets begin to burn, which starts the ventilation in the fire chamber. In addition, an air stream passes through the ashtray. Thanks to this, the flame is fanned.

As soon as the stove is started, normal operation begins. It loads the ash pan by means of the worm screw and at the same time ventilates the chamber. Because the stove has several heat sensors, when the sensor corresponding to the fire chamber detects fire in the ash pan, the stove knows that it is lit. Thus, it will start the ventilation of the exchanger to remove the heat from the stove to the outside.

When another heat sensor discovers that the desired temperature has been reached (the one we have previously indicated on the control panel), the stove will stop the combustion and will start heating again as soon as the temperature is below what has been indicated.

How does the stove heat? The stove heats mainly by means of adjustable ventilation. The cold air that enters the machine passes through an opening at the back of the appliance. It then passes through the heat exchanger and is expelled through the front (or even ducted)

There is no need to worry about any problems related to fire or combustion gases from the appliance, as the air is never in contact with them.

Pellet stoves, likewise, heat the space in which they are located through the window corresponding to the “combustion chamber and chassis”. When the stove is turned off, the auger mechanism finishes pouring pellets into the ash pan, and the appliance ceases to function.

If what you want is a ductable pellet stove, perhaps the way it operates will change. This is because a ductable pellet stove needs more power to be able to distribute the heat throughout the house through ducts. At the same time, it must have the appropriate channeling for it, which is usually installed on the roof of the house.

Types of pellet stoves

The types of pellet stoves can be differentiated in design or operation. If we are interested in the first group, we find the round ones, the corner ones, the inserts, the corridor ones, the built-in ones or the wall ones. But if we want to go deeper into the second group, we should know the following:

  • The ductable air stoves: these are used so that the heat is distributed by means of special ducts. They work in a very similar way to air stoves, but they expel all the warm air through the front of the appliance. These in particular, are a good option for homes with several floors or rooms.
  • The air stoves are designed to heat the room in which they are located. They use a fan at the front of the stove that the space to heat up quickly. In a simple way, they are characterized by a programmable and electronic on/off system

Inside, a fan blows hot air to the outside that the walls of the appliance exchange with the flame. They have a system to know if there is an excess temperature for greater safety, with a door on the stove that opens.

  • The hydrostoves or thermo-stoves to get closer to what they are, we should describe them as a type of “boilers”, which have the capacity to heat the whole house, through their connection to the radiator circuit connection with the circuit of the radiators already in the house. An interesting feature is that they are able to produce domestic hot water if an external storage tank is installed

Like the air stoves, they are equipped with a safety mechanism to detect if the appliance reaches too high a temperature, or even a pressure above normal. They also have at their disposal a programmer and an electronic ignition system.
