Thermal Photographs

We received a delightful email from a customer who made infrared images of one of our Kachelofen. The results are fascinating!

This is a side view of the unit. You can also see the outline of the front door to the immediate right of the oven.

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.

The outline of the firebox can be clearly seen at the bottom of this image.

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!

This is what the oven looks like “normally!”

Thank you so much to Patrick and Karen for sending us these infrared images!
