Principles

Variotherm system wall or easyFlex wall heating/cooling installations are a source of well-being. they provide heating through horizontal radiant heat instead of the ascending warm air provided by conventional heating systems. this avoids the permanent movement of air and the associated stirring up of dust. rooms are evenly heated without different temperature zones in the heated rooms. By the way, solar heat is also radiant heat.

Cosiness

cosiness is not only created through a certain air temperature in the room. the temperature of the surfaces enclosing the room is of equal importance. The perceived temperature is roughly consistent with the arithmetic mean of both temperatures.

What Makes People Feel Cozy?

People feel cosy when the following basic “thermal cosiness” equation holds:

Principles

Heat Production = Heat Loss

in this context, it is important that heat loss from the human body is as evenly distributed in all directions as possible. We feel uncomfortable if too much heat is lost in one particular direction (e.g. cold surfaces, draughts) or the heat loss is prevented in one direction (hot surfaces or vapour-tight, thick clothing).

The lower the inside air temperature is, the warmer the surrounding surfaces (wall surfaces, floor and ceiling, as well as doors and windows) must be to ensure cosiness.

compared to other heating systems, the system wall or easyFlex wall heating/cooling installations significantly increases cosiness. the installation of surface heating on an exterior wall, especially under windows, can largely cancel out the unpleasant effects from the radiation exchange between your body and cold exterior walls and windows. you can set the room temperature lower than you would with convection heating, since radiant heat raises the perceived air temperature.

Energy Savings

Energy losses are minimised with a lowered room air temperature along with the increased cosiness. The approximate cost savings per 1 °C lower room air temperature are 6%. The low room air temperature has the additional great physiological advantage of significantly increasing the absorption of oxygen in the body. The wall heating system is ideal for use with low-temperature energy sources such as condensing boilers, heat pumps and solar collectors because it operates with low surface and heating medium temperatures. With the Variotherm wall heating you can achieve energy savings of up to 30% compared to conventional heating systems.

Adapts To Suit Your Home

The Variotherm wall heating utilises the existing or intended exterior wall, either as an additional storage medium (if full exterior insulation is present) or as insulation. The wall heating surfaces can be individually adapted to suit the local situation (windows, doors etc.). Visible radiators under the windows are a thing of the past.

Temperature Variations/Wall Structure

Various different wall fittings at a wall surface temperature of 30 °C and a standard outdoor (air) temperature of -14 °C.

System Description

Variotherm offers two different systems for installing a plastered wall heating/ cooling system – systemWall and easyFlexWall – which differ in the type of plaster and pipe dimension used. Depending on the subsurface, the VarioBars are attached to the (outer) wall using screwFix or nail anchors and the VarioproFile pipe is clamped into the VarioBars, starting from the distribution manifold. There are own retaining clamps for fastening the return to the wall. the plaster is applied after installation.
