We received a delightful email from a customer who made infrared images of one of our Kachelofen. The results are fascinating!
The inner flue system of a Kachelofen is built with much thicker firebrick at the bottom than at the top. As the heat travels upwards through the oven, the firebrick becomes thinner and thinner. This is done so that the bottom heats up more slowly than the top. In theory this means that the entire surface of the unit heats up at a constant rate.
Every oven will have a few “hotspots,” but the overall effect should be a thermal mass that radiates evenly and slowly. It’s so nice to see that effect in these photos!
Thank you so much to Patrick and Karen for sending us these infrared images!
We’re off to the Blue Ridge Mountains this December to install a two-sided kachelofen in an historic century cabin. It all seems like an idyllic winter wonderland, and a perfect location for one of our stoves!
The main stove will be decorated with a traditional, hand drawn slip-trailed pattern. This is a photo of the pieces laid out on the floor of our studio:
The home owner decided to add another unit on the other side of the wall. The flue network will pass through a shared wall. This way two rooms can be heated with a single fire. Here are the bricks for the second oven laid out:
The concave shape of the “Schüsselkacheln” increases the radiant surface area of the bricks. This allows a slightly more compact oven design to radiate enough warmth for the area that needs to be heated.
The bucket of blue “wedgewood” glaze can be seen in the foreground of this photo. This was a wonderful glaze to work with. We work exclusively with Spectrum Glazes to achieve a wide range of results! Spectrum is a Canadian company that is a worldwide leader in glazing technology.
