The room temperature alone does not determine whether a room climate is comfortable or not. It is important how the heat is absorbed by the person. Because: Heating not only affects the room temperature, it changes everything Indoor climate.
In general, there are two different types of heat transfer in closed rooms. While radiators emit heat to the room through convection (air movement), surface heating systems work with radiant heat. But what's the difference?
What is convection heat?
Convection heat heats the air and distributes it around the room. The heat is transferred from one place to another by means of air movement, known in technical jargon as convection. The air is therefore the heat carrier. This often creates drafts in the room that are perceived as unpleasant.
A convector moves the air and thus stirs up dust. This can be uncomfortable for allergy sufferers.
What is radiant heat?
Radiant heat can be compared to sun rays: If these infrared rays hit solid surfaces (e.g. walls, furniture), they are gently and gently warmed up. This energy is released into the room as heat. The person is thus warmed “from within”.
Who does not know that? If you sit in the sun in a ski hut in winter, a T-shirt is usually enough. In the shade, however, you need a jacket in order not to freeze.
Which heating gives off convection heat and which radiant heat?
Conventional radiators, air heaters and convectors mostly work with convection heat. Surface heating (wall, floor, ceiling) and tiled stoves warm the room pleasantly and comfortably by means of soothing radiant heat. The heat is transferred directly from the surface to the body.
What is surface heating?
Surface heating emits its heat to the room through the wall, floor or ceiling. How? Heated or cooled water flows through the pipes integrated in the surface. The pleasant radiant heat makes people feel good. The surface heating is installed invisibly in the room and leaves a lot of freedom in interior design. And: In summer it cools the rooms effectively and comfortably.
If you want to install surface heating afterwards, the Variotherm dry construction systems can be installed quickly and easily.
Which is better: surface heating or convector heating?
This question can be answered clearly with "surface heating". Because in addition to the advantages mentioned above, it is a future-oriented and sustainable heating system. Since it heats and cools over a large area, it can be operated with low flow temperatures of 25 ° C to a maximum of 38 ° C. Due to their small size, conventional radiators work with a flow temperature of approx. 45-60 ° C. In this way, surface heating not only saves money, it also protects our environment.
