The following components of the monolith depot work together for this:
The heart of the monolith depot is the accumulator core. This is where the first phase of heat storage takes place. The entire accumulator core consists of heavily compressed accumulator refractory clay system elements. The formulation of the refractory clay is adapted specifically to the requirements of the monolith depot. The manufacturing process involves compressing this special refractory clay material into the shaped parts under extremely high pressure and then firing it.
The accumulator core functions according to the "floor burner principle" – i.e. it consists of a fire chamber and the following ducts, the smoke extractors – all made from refractory clay. The high temperatures and gases which are then formed during burning are diverted through the smoke extractors on the way to the flue and are stored there. Refractory clay is ideally suitable for storing heat. The smoke gases cool down on their way to the flue – as much energy as possible is kept in the stove – only the bare essential heat is allowed to reach the flue.
For example, in tests the monolith depot_G1 achieved an efficiency level of more than 90%.1
The second storage medium after the accumulator core is the natural stone casing.
Natural stones are formed over millions of years under enormous pressure. The consequence of this is that natural stone is typically extremely dense and very heavy. Accordingly, natural stone is a very good heat storage medium. Very heavy materials usually have greater storage potential than materials with less mass. For example, natural stone has greater mass than kiln ceramic. The two constituents natural stone and refractory clay thus make an excellent combination and are ideal for delivering long-lasting, comfortable radiated heat for many hours.
The monolith depot_L2 | L3 stove models weigh over 800 kg, for example.
Each monolith depot consists mainly of three different components specially harmonised components:
This represents the first storage unit and ensures a high degree of efficiency
This assures good insulation and durability
The sophisticated design and combination of these elements delivers an enormous storage mass, and consequently also outstanding storage effect and very high efficiency.
The exceptional storage mass of the monolith depot means that heat energy is radiated for a long time The result: Many hours of radiated heat without recharging. In comparison: In a steel fireplace, wood must be added much more frequently, because its storage mass is smaller. The constant heating and cooling leads to more pronounced temperature fluctuations – with the monolith depot, the room temperature is more constant.
The entire accumulator core consists of heavily compressed accumulator refractory clay system elements. The formulation of the refractory clay is adapted specifically to the requirements of the monolith depot. During the manufacturing process, this special refractory clay material is compressed into the shaped parts under extremely high pressure and then fired.
