Infrared heating


Infrared - radiant warmth

Infrared heaters are radiant heaters. They produce a simple heat radiation that is transported by infrared waves.There are both dry and water-bearing models. This type of heating does not heat the room air, but bodies, components and objects that are hit by the infrared wave. The ambient air remains significantly cooler - and therefore also fresher. Infrared heating thus contributes directly to a higher air quality in the room.

The human body absorbs the infrared and thus heat radiation emitted by the wall in its entirety. The transfer and absorption of heat energy is thus much more efficient than, for example, with underfloor heating, where the heat is only absorbed via the feet. The lateral heat radiation feels similar to the warming radiation of the sun, which is also transmitted via infrared waves.

The building biology concept envisages and strives to adopt optimal natural conditions and to continue or imitate them in the living space structurally.

Advantages and installation

Water-bearing infrared heaters are very energy-efficient due to the very low flow temperatures of around 35 ° C, especially in combination with a solar thermal system. In Autumn and Spring, solar thermal systems reach these flow temperatures very quickly and thus record good utilization, as the thermal energy is used directly.

Another advantage of wall heating is the even surface temperature of the wall and window surfaces. (As an exaggerated counterexample, use the large, single-glazed window, including a powerful cast iron radiator with a surface temperature of 60°C: warm legs and a cold upper body are the result. The human body perceives such different temperatures as extremely uncomfortable. The goal is one evenly high perceived temperature in all areas of the living room. The wall heating with a flow temperature of 35°C is as warm as a double-glazed window.)

It is ideal to mount such a flat heater on an outside wall. This wall is significantly drier than an outside wall without heating. As a result, it has better insulating properties, the risk of mold formation is significantly reduced and thermal bridges can be avoided.

Infrared and wall heating can be ideally integrated into the planning of the living space, as they are perfect for 'comfort zones' in the house: in the dining room, work room, quiet zone or sitting area, the heating elements are condensed, other rooms that are not used for permanent residence are only provided with a few heating elements that ensure the basic heat. For structural support, wall heating can be used specifically in places that are only weakly insulated. The lack of insulation can be compensated there.

Determine the heat input

Before installing wall heating, there is one important thing that you should consider: it cannot simply be installed on every wall and on every surface. The total heat loss of the building should be calculated beforehand in order to determine the required heat input. With this knowledge, the necessary total length of the heating pipe can be determined. A comparison with the existing wall surface shows whether the possible heating surface is sufficient for the building. Wall heating is profitable and makes sense with a minimum insulation value that can easily be achieved in a half-timbered house. In an existing building without further insulation, you should do without it.

Further wall use

A further restriction or at least a risk with regard to the installation or use of a wall heating system results from the fact that there is a risk of hitting one of the pipes when hanging objects on the wall. If the exact position and distribution of the heating pipes is no longer known, this can be easily checked, especially with clay plaster, by popping a small hole in the intended place with a screwdriver. A thermal film indicates warmer and cooler places, and the position of the pipes can also be determined with an infrared thermometer or a thermal imaging camera. A risk-free nailing and screwing into the wall is possible. If the planning of the heating installation allows it, it is advisable to equip the wall behind large furniture such as cupboards only very sparingly. Too much heat energy is lost through wardrobes in particular. Small furniture and also bookshelves (without a back wall) allow enough warmth into the room.
