System Description

Wall heating is very similar to floor heating in terms of principle of operation and operating conditions. The advantages of this method are large-scale radiant heat and particularly the capability of a rapid response and thus faster room heating. These properties make wall heating a viable solution for a wide range of applications such as health care, industry, public buildings as well as private homes.

Another possibility of use is special areas where it is necessary to prevent dew formation on the walls (swimming pools, baths).

Due to the heat radiation from the wall and owing to almost ideal temperature distribution it is possible to reduce the room temperature by 3 oC – 4 oC and any room temperature reduction by 1 oC represents energy saving of 6 %.

In the areas where wall heating is installed, there is no piping which allows greater flexibility of interior equipment and visual expansion of the room. The great advantage of wall heating is its use as separate heating but also as a supplement to floor heating.

Wall heating is suitable for:

  • family houses
  • community buildings
  • sanitary facilities
  • outdoor swimming pools
  • rooms with an indoor swimming pool
  • rooms with a higher moisture content
  • industrial and production halls

Hot water wall heatingis a piping system placed in a wall through which water flows. Just as floor heating, also wall heating is one of the radiant heating methods while the share of the radiant component in the overall heat transfer from the heating surface is higher than the heat flow by convection (65% : 35%).Since the heating pipes are a part of the wall structure, this makes wall heating a large-scale heating solution.

Depending on the temperature of the heating medium the system's aim is to heat (in winter), eventually cool (in summer) the wall surface.  In terms of harmless environment the relative air humidity is significantly higher, corresponding to a lower air temperature at the same thermal comfort, and  wall heating does not create a significant air flow, no air turbulence and dust overburning

Wall heating pipes RadianoxyUNIVENTA Radianoxy 14x2 mm

The basis of wall heating is a top-class RADIANOXY pipe with a polybutylene core which is perfectly flexible. The pipe contains 100% oxygen barrier of aluminium. By using this pipe the system is perfectly protected against air intake.

  • original polybutylene PB 4135
  • homogeneous core
  • polyester reinforcement
  • 100% oxygen barrier
  • the maximum temperature difference between the supply and return piping must be maintained in the range between 5 °C and 10 °C (heating)
  • the maximum temperature difference between the supply and return piping is max. 3 °C (cooling)
  • in terms of ideal temperature distribution and from a hydraulic point of view, we recommend to choose a maximum length of piping of 60 lm to 80 linear metres while the length of heating circuits should be approximately equal
  • the design of wall heating should be appropriately based on the same medium temperature of heating water for each room
  • the heating pipe should be placed on the wall with a minimum distance of 10 cm from the edge of the wall (or from the edges of windows and doors)
  • placement of the heating pipe is selected so that the inlet is at the bottom of the wall
  • the inlet water temperature to the wall heating system should be in the range from 55 °C to 60 °C; it should never exceed 45 °C while using gypsum plaster
  • wall heating is normally placed to the maximum height of 2 m above the floor
  • expansion joint of the heating surface. The heating wall needs to be separate along its entire perimeter. When the length of building parts is more than 6 m the expansion joints must also be planned. In order to create expansion joints, the finished dilatation profiles can be used, or the wet plaster can be cut and the joint filled with a flexible sealant. In the case of pipe passage through the expansion joint or the wall, it should be secured by a PE protector at the passage point with 250 mm overlapping on both sides. The exact layout of expansion joints depends on the composition of a plaster mixture and needs to be discussed with the plaster mixture supplier
  • the location of the manifold for wall heating must be situated so that the transports into individual rooms are approximately the same
