The radiated warmth of the monolith consists of long-wave infrared radiation. This radiated warmth passes through the air without heating it up very much, like solar radiation, and then it encounters solid objects such as floors, walls, furnishings, etc., and warms these up. The objects and walls heat up and then they in turn give off warmth. This creates an optimum heat distribution throughout the room. Air temperature both horizontally and vertically is very even. Strong air circulation leading to dry, dusty air is suppressed. The outer wall surfaces are warmed with radiation heating, so they also contribute to the feeling of comfort to a degree. Excess atmospheric humidity from cooling air can no longer condense on the walls because its temperature is controlled.
A person's skin has an area of approximately 1.5 to 32 square metres, and has more than four million receptors, which makes it the largest and most sensitive of human organs. It regulates our temperature and moisture balance. A quarter of our blood flows through our skin, and a third of our water reserves is stored here. The gentle radiated warmth now spreads a particularly soothing effect all over our bodies through our skin: our muscles relax, the entire organism is revived – people just feel better.

WHO DOESNT'T KNOW THIS FEELING FROM SKIING...
The mode of operation of radiated heat is very noticeable when skiing. In winter, the air temperature is cold. But if you stand in the sun, you perceive the temperature to be many degrees warmer than in the shade. This is radiated warmth at work.
In general, heat can be emitted by a stove system in two different ways: as convection heat – that is to say warm air, as radiated heat or a mixture of these two heat forms. A classic representative of mainly convection heat is the steel fireplace, for example.
Convection heat heats the air up. sets it in motion, generates vertically varying heat zones. Temperature differences of several degrees Celsius (floor cold – ceiling hot) are the result. In addition, the cold walls reflect cold back into the room.*
e.g. monolith depot
Radiated heat spreads smoothly throughout the room from the fireplace in long waves, creating a homogeneous heat zone, warming people, objects and walls. All of these objects and walls then radiate the warmth back themselves.*
