Wall heating - the assembly


More and more often, the wall heating is selected as a heating system with special advantages. Although the installation of the wall heating is similar to that of the underfloor heating, it is much simpler. We will then summarize how you will install a wall heater.

Convection heating versus radiant heating

The wall heating works as a radiant heater. This sets them apart from conventional heaters with radiators that generate convection heat. In the convection heating, the room air is heated, in the radiation heating of the illuminated body or object.

While for the sensation of 21 degrees Celsius room temperature in the convection heating actually have to be reached 21 degrees, the radiation heating for the same sensation only 18 degrees are needed. Considering that for every degree of heat more than 18 degrees in a convection heating six to seven degrees more energy is needed, the benefits are already evident.

Large area requirement for the installation of wall heating

For this, the wall heating must be designed over a large area. When designing the wall heating, you can roughly assume that 20 to 30 percent of the living space is needed as a wall surface. In addition, the wall heater must preferably be mounted on the outer wall. For example, what are the consequences of a wall heating in the old building without heat insulation, you can read here.

Therefore, an external insulation is extremely important because otherwise radiates much heat to the outside. This will require a higher flow temperature, which means more energy costs. Before installing the wall heating must therefore first be done the wall insulation. Alternatively, a facade insulation from the outside is possible.

For the installation of wall heating you also need material:

  • Clamping rails, suitable for the composite pipe
  • Heating tube, preferably a plastic-metal composite pipe
  • possibly a distribution box (distributor for several cycles)
  • alternatively connection distributor on the heat generator

Assembly of the clamping rails for the heating pipes or heating coil

First, the clamping rails are mounted on the wall. Depending on the manufacturer, these can be glued on beforehand and screwed on after fixing. When fastening the clamping rails, make sure that the distances to the wall, floor and side walls are correct.

Because outside the clamping rail, the heating tube must later be bent in a sufficiently large radius. The manufacturers of the clamping rails usually provide instructions for use, from which the exact distances (also to each other) emerge.

Laying the heating coil

Now the heating tube is used. They start from below with the inlet. Then the heating coil is laid meandering, so a narrow radius for the next row, on the opposite side of the opposite radius for the next row, etc. From top to side outside then the return is still down. Now supply and return can be connected to the distributor.

Tips & Tricks

You can dress the wall heating in dry construction. Alternatively, you can plaster the wall heater. Especially when plastering plaster and thermal stress are matched. Our guide shows in detail what to pay attention to.
