Frequently Asked Questions about pellets

Why the pellet?

The pellet is a fuel that has existed for several decades (50 years).

The pellet is currently the most stable non-polluting fuel in terms of biofuel, provided that it meets the quality standards guaranteeing a constant calorific value.
This small pellet composed of sawdust has a calorific value of about 5Kw per kilo of pellets which is 2 to 3 times higher than the calorific value of firewood.
A recent Swedish study tells us that we can heat all Europeans by using wood waste, wood chips and wood while guaranteeing sustainable management of our forests. The European forest park is constantly growing, and there is more forest than in the Middle Ages. Each tree with a diameter of less than 25 cm has no market value because it can not be used in carpentry. 10% of the felled woods (thinning of young stands, etc.) are left on site and could be reused in biomass.


What are the pellets made of?

The pellets consist of compressed noble sawdust, without any additives.

What is the consumption of a pellet stove?

1 kg of pellets = 5 KWH. The full tank capacity of the device allows a 30-hour autonomy.

Does the pellet stove produce a lot of ash?

The combustion of pellets yields only 1% of ash. The amount of waste is therefore minimal and therefore requires little maintenance. A simple vacuuming around the crucible is sufficient.

Will there always be pellets and at what price?

Pellet is a fuel in its own right. In Austria, Switzerland and the Scandinavian countries, 60% of new buildings are equipped with this heating system. It is a fuel of ecological future. In Europe, we have a lot of wood waste and at present a very small amount is recycled. As long as there is sunlight, there will be vegetation and therefore waste wood to be valued.
In Belgium the law obliged to replant every felled tree. As for the price of pellets, it is not subject to variations such as gas or oil. At present, its price is bound to decline, given the number of factories in Belgium, transport costs are reduced.

Is there a lot of dust?

No, the door of the stove must only open for maintenance (ash extraction and cleaning of the window), it is a closed combustion chamber, so there is no dust or soot or spark on the ground. Pouring a bag of pellets into the tank will not cause dirt. The pellet is a clean fuel, it does not smell, stain and can not explode.

Where can I buy pellets?

7 factories in Belgium produce pellets and new factories are appearing here and there. There are currently more than 230 factories in Europe.

How to store pellets?

The pellets are packed in waterproof bags and are easily stored in a dry place.

Can the power of the stove be reduced at certain times of the day?

Yes, the integrated thermostat and timer systems allow you to choose the desired temperature at any time of the day. For example, you can program your stove to turn on from the morning until you go to work and ask it to turn on again 1/2 hour before you return and go out at bedtime. Several programs are possible (week, weekend, night). However, you can always turn your stove on or off outside of programming hours by using the manual mode.

Heating with pellets, is it economical?

The pellet stove is equipped with a thermostat. When the desired temperature is reached, the stove automatically decreases its consumption. Indeed, the screw will rotate more or less quickly according to need. Thus delivering the required amount of pellets to the combustion chamber.

What is the performance of a pellet stove?

A pellet stove has a yield of +/- 87% (a wood stove represents a 65% yield), so almost all the heat is returned to the room. Our SÛTI pellet stoves have a yield of 93%

I do not have a fireplace, what to do?

The installation of a pellet stove does not require a chimney. A coring in an external wall. and a duct or a tight nozzle are sufficient (under the advice of a professional).
