Never heat the wrong way again: how an electronic combustion control works
A combustion control adjusts the combustion air of your stove all by itself, from lighting the fire to the embers. In just under three minutes our explainer film shows how it works and what you gain from it.
On most stoves the combustion air is still set by hand, usually by feel. If you close it too early, the fire gets too little oxygen and the wood starts to smoulder. This produces soot, fine dust and toxic carbon monoxide, and the glass quickly turns black. If the air stays open all the time, a large part of the heat escapes unused through the chimney, and the wood is used up quickly.
How the combustion control works
A sensor continuously measures the temperature in the firebox or at the flue outlet. The control unit evaluates it and decides how much air the fire needs right now. A small servo motor then moves the flap in the combustion air duct, exactly as far as necessary. You can see the status on the display or conveniently in the app.
Three phases of a good burn
- Lighting: The flap is fully open so that the stove quickly reaches its temperature.
- Main burn: The control throttles the air steplessly, and the fire burns calmly and evenly.
- Embers: The flap closes completely. No more cold air is drawn through, the chimney does not cool the stove down, and the heat stays in the room longer.
What you gain
- Less wood: up to 50 % compared with operating the stove with the air supply permanently open. How much it is in your case depends on how you have been heating so far.
- A clear glass more often: Nobody can guarantee it, but the chances are much higher. Read more under Why the glass turns black.
- Less fine dust and CO than with incorrect operation.
- More peace of mind: You no longer have to remember to close the air.
You can heat well by hand too if you are careful. With the control, however, the wood burns with less soot, for longer and more economically. This is particularly worthwhile for heat-storing stoves and water-bearing systems, because more heat reaches the storage.
Factory-fitted or retrofitted
Many manufacturers already offer the combustion control as a factory option. And where it is not available for your stove, we will find a solution with you. Talk to us or send us an appointment request right away.
