There is nothing better than a fireplace: a fireplace with a heating cassette. The joy of the blazing fire remains, but there is also cozy warmth throughout the room. And when there is no fire, the fire pit still looks good.
Viewed soberly, a fireplace without fire is a cold one, drafty hole. When fire blazes in it, it is different, but not necessarily more comfortable: who is sitting in front of it, is heated from the front and cooled from the back, for the fire draws a steady stream of fresh ones, cold air. Most of the combustion heat disappears through the chimney. In numbers: The heating energy, stuck in the wood, comes only to about 15% benefit the room, 85 % remain unused. A heating cassette not only improves efficiency (85 % of energy are used), but is also comfortable. Don't worry about the fire anymore, when you leave the room, no ash, which is then distributed in the room. If the fireplace is burning now, the wood crackles and cracks and it just gets warm.
HOW TO WARM THE AIR
The heating cassette is built like a double-walled tub. At the bottom, cold air enters the intermediate space through the air inlet fins, heats up on the combustion chamber walls and the heat exchanger tubes and leaves the furnace at the top of the air outlet fins.
The combustion air is drawn upwards into the chimney, after it has passed the heat exchangers.
