Clay with its thermal properties is a building physics issue that is apparently full of contradictions. In fact, the word 'apparently' is applicable here: from a real point of view, clay is a multitalented thermal technology. It transfers and stores heat and also keeps heat away that might penetrate the house from outside.Therefore, clay walls in connection with wall heating form a great partnership.

Clay has fantastic thermal properties: On the one hand, it transfers heat well. If you have two wall heaters with the same target amount of heat, one with clay and one plastered with lime, you can install two completely different amounts of heating pipe for the same heating output. In short: you need twice as much for lime plaster. Clay plaster dissipates heat well because of the water it contains. The more mass the wall heater surrounds, the better it can radiate heat well and evenly. On the other hand, even if that seems contradictory, it is an excellent heat store. A basic stove, for example, only works well if it has a decent amount of mass: if it is fired once a day, it stores the heat and releases it gradually and evenly as cozy radiant heat, just like wall heating neatly wrapped in clay plaster. These two important thermal properties, namely the good heat retention capacity and the ability to store heat for a long time, make clay, in combination with heating and stoves, the ideal building material.
