The pellet stove: the principle

The Principle

The principle of the pellet stove is to produce heat by burning a fuel.

The fuels used are wood pellets from industrial waste from the wood industry.

There are also wood pellet boilers that are installed to replace a conventional boiler.

This makes it possible to heat the home and produce domestic hot water.


A very high efficiency of up to 95%.

The possibility of automated pellet supply and therefore the programming of the start up.

A simplicity of implementation.


The pellet stove using wood as fuel is eligible for the tax credit to promote the use of renewable energy.


By using industrial waste from the wood industry, the trees are preserved.

An ecological gesture to preserve the planet.

How How does it work?

How does it work?


Pellet stoves have the same operating principle as a fireplace. It uses the heat emitted by the combustion of pellets.

Pellets are made from the waste products of the wood industry. More compact, it facilitates storage. Their combustion is slower and emits much less ash than conventional wood logs.

Pellet stoves are usually equipped with an automated pellet refill system.

thus allowing an autonomy of several days of operation.

Some models are even equipped with a timer and an automatic ignition giving a comfort of use unequalled by a classic fireplace.

A very pure aesthetic: Pellet stoves do not require any exterior cladding and contribute to the decoration of the room with very design and contemporary lines.


Pellet boilers have the same operating principle as a classic boiler.

The combustion of wood pellets will emit heat for the heat transfer fluid that feeds the central heating circuit of the house (usually water).

The wood pellets are replenished directly from the silo to the boiler via a pouring system that can be automated because of the small size of the pellets and the ease of transporting them in a circuit.

The installation of a pellet stove: implementation

Mise and oeuvre

The installation of a pellet stove is not very restrictive because it only requires a flue pipe.

The pellet stove is then either connected to an existing chimney flue or to a horizontal outlet via a vent created on the wall.

A power supply is also required for ignition. This is done by means of an electrical resistance that will ignite the wood pellets.

The power station will autonomously manage the operation of the pellet stove according to the various data recorded: desired temperature, programmed heating period, etc….

Pellet stoves are equipped with an ambient air temperature sensor for optimum comfort. The room air fan will spread the heat emitted by the pellet combustion in the room to be heated.

A worm gear motor automatically feeds the pellets into the combustion tank until the desired room temperature is reached. The pellet stove then switches to economy mode.

Pellet stove tanks have a capacity of between 15 and 35 kg of wood pellets.

The ashes from burning wood pellets represent only 1% of the pellets.

Since the heat emitted by pellet stoves is very dry, they are generally equipped with a humidifier that allows essential oils to be added to the air to perfume the house.




Pellet Stove ConstructionTechnical characteristics of pellet stoves

Technical characteristics

Pellet stove power (in kW): this is the heating capacity of the stove. The choice of the power will be made according to the surface area of the room to be heated but also according to the energy performance of the house and the climatic data of the place.

The efficiency (%): This is the amount of energy produced in relation to the amount of energy consumed. Note that to be eligible for the tax credit, a pellet stove must have a minimum efficiency of 70% for which the carbon monoxide concentration must be less than or equal to 0.6%.

The average consumption (in kg/h): Important data to take into account since it corresponds to the consumption at the time of pelleting. The programming of pellet stoves, which allows them to be switched to economy mode as soon as the desired room temperature is reached, significantly reduces the average consumption of the stove.

Tank capacity (in kg): The larger the capacity of the tank, the longer you can heat the pellet stove.

How much does it cost to install a Pellet Stove?

What is the cost?

Installing a pellet stove is a major investment

which will be amortized by the energy savings achieved.

Since the price of a pellet stove depends on the heating power needed to heat a room, it is difficult to give a price range.

As far as wood pellets are concerned, this energy is more economical than the commonly used energies (fuel oil, gas…) and varies between 190 and 360€ per ton.

Tax credit for the installation of a pellet stove A REDUCED INVESTMENT THANKS TO THE TAX CREDIT.

The French state wishes to help the development of the use of renewable energies.

15% tax credit for heating or hot water production equipment

running on wood or other biomass.

What amount of expenses does the tax credit apply to?

The tax credit covers the price of equipment and materials, excluding labor, meeting the characteristics.

What is the amount of expenses eligible for the tax credit?

For the same taxpayer and the same dwelling, the amount of expenses eligible for the tax credit may not exceed, for a period of five consecutive years between January 1, 2010 and December 31, 2015, the sum of € 8,000 for a single person, widow or divorced and € 16,000 for a couple subject to joint taxation. This sum is increased by €400 per dependant within the meaning of Articles 196 to 196B.

To find out your rights to the tax credit, you are advised to refer to the provisions of article 200 quater of the General Tax Code.

For the application of this measure, it is strongly recommended to refer to :

The website (page on the tax credit)

Article 200 quater of the General Tax Code, Article 90 of the 2005 Finance Act, Article 83 of the 2006 Finance Act, Article 109 of the 2009 Finance Act and Article 80 of the 2010 Finance Act.

The tax instructions 5B-26-05, 5B-17-06 and 5B-17-07

The decrees of February 9, 2005, December 12, 2005 and November 13, 2007 issued for the application of articles 200 quater and 200 quater A of the general tax code relating to capital expenditure on the main dwelling and amending annex IV to this code

Sections 81 to 83 of the 2012 Finance Act

Financial aid for the installation of a pellet stove from the AIDES REGIONALES, DEPARTMENTAL, and ANAH.

Some regions, town halls or the ANAH also subsidize the installation of photovoltaic panels by granting financial aid. Find out more directly from these administrations or from your ESPACE INFO ENERGIE.

VAT reduced for the installation of a pellet stove VAT REDUCED TO 7% FOR LIVINGS OVER TWO YEARS.


You divide by 2 your energy consumption for the heating of your home compared to an oil heating system.

This can represent several hundred euros per year.

With the tax credit, the various financial aids and the energy savings made, the investment of a solar water heater installation is amortized in a few years.

Pellet stove: environmental impact

Environmental impact

Wood pellets are made from wood chips and sawdust resulting from waste from the wood industry.

The environmental impact is net since the quantity of wood pellets burned for heating corresponds to the quantity of tree not felled and therefore preserved.

Global agreements are being put in place so that the removal of wood from forests is compensated by the planting of young trees to preserve future generations.

Finally, unlike other fuels, wood does not contain sulphur and the carbon monoxide emitted during its combustion can be divided by 40 for high output automatic boilers.
