Lehm und Feuer uses modern technology and trusted furnace construction tradition. Our artistic values and 17 years of experience help us to create constantly a new face for the classic tiled stove. The challenge of any project is to meet the requirements of the customers individually, the characteristics of the place and the existing and future heat supply. Ultimately, it is the whole concept, which does not impress only by its technology, but by donating heat to the people simply because of its shape.

We want to establish not only artistic values, but we are convinced that holistic approaches are the path to genuine quality. We place special emphasis on sustainability – not only ecological building materials, but also CO2 neutral heating and a conscious use of our resources are part of this holistic approach.

For us as furnace manufacturers and certainly as artists, the whole house, its inhabitants and their habits are always taken into account since a furnace as a heat generator and as an art object has a significant impact on all three factors mentioned above. This responsibility is a new challenge every time and depends on the cooperation of all parties involved. We create unique items that have a real connection to the house and its inhabitants. The coherent form is therefore always the result of the technical needs of the customers and the creative process that connects us with everything in the project. A vibrant, timeless design has a big impact on the space and creates a constant atmosphere of well-being.

The furnace is the heart and center of the house. For generations it has been the common meeting place of the family, the retreat and the source of heat. The furnace invites you to touch, use and rest. It combines radiant warmth with effective heating.

Clay and fire – that’s Peter Löffler, Daniel Koch and Maximilian Löffler


CO2 neutral heating:

Burning wood releases only as much CO2 as the tree has bundled during its growth and would release during the composting process.
In consequence, all furnaces use only renewables and no fossil fuels like oil or gas. Even if the price of wood has been increasing for years in Germany, it always remains at a much lower level than the price of other fossil fuels. A major point of criticism for the responsible use of this renewable resource is the effectiveness of the system. Unfortunately, the effectiveness of so-called “DIY stoves” is insufficient, although these stoves are largely the motor for the increasing demand for firewood.

Ecological building materials:

We use clay plaster from CLAYTEC, Grünlinge (unfired clay bricks) and color/clay- fixation from HAGA.

Below you will find a brief summary definition of the great benefits of this specific building material stated by the Umbrella Association of Clay:

“Like no other building material clay fulfills biological and environmental building requirements. It is available locally, protects resources and is freely recyclable. The production is energy efficient; it is comfortable to work with and produces no pollutants. The building material clay improves the indoor climate significantly. By the uptake and release of water vapor, it regulates the humidity in a natural way. It also offers good sound insulation due to its mass and thermal storage properties.”

Conscious use of resources:

Since the durability of the furnaces is very important to us, we can rely not only on ecological building materials. For example, on the issues of fire protection and reinforcement, we do not make any compromise. With the first issue, fire protection, we rely on vermiculite, which is completely harmless to health but needs a lot of energy during the production process. We are forced to use the prescribed silicate-based adhesive otherwise the insulation loses its approval. However, the quantities used are rather small – as well as the use of fiberglass, which we need to create a crack-free clay oven. We are constantly looking for more suitable materials and are optimistic to have access to better ecological building materials in the future.
