How high must the heat storage capacity of building materials be? As always, the answer is "it depends". In a tiled stove the heat source (the fire in the open) is not controllable in its intensity. Here it is crucial that the material of the stove absorbs the heat energy, stores it for a long time and slowly releases it into the room. The disadvantage is obvious: the reaction time is extremely slow. However, if the heat source can be controlled by thermostat, as is the case with wall or ceiling heating, then a high heat storage capacity leads to unnecessary inertia of the system.
The naturbo therm wall heating or ceiling heating system takes the golden mean here: it has sufficient mass and thus heat storage capacity that it can emit heat very well. At the same time, the mass is reduced to such an extent that it belongs to one of the fastest reacting, water-guided heating systems.
