Brief summary
• The basic principle of wall heating: As an invisible surface heating system, it utilizes free wall areas to emit cozy, even radiant heat into the room. This eliminates bulky radiators, allowing maximum freedom in interior design.
• The different types of systems: Beyond cost-intensive electric heating mats, modern hydronic systems form the core segment. Depending on the construction project, a distinction is made between prefabricated gypsum fiberboards in dry construction (ideal for renovations/sloped ceilings) and plastered systems (direct mounting on the wall covered with plaster).
• Functionality and energy efficiency: Warm water circulates through large-surface heating pipes installed in the wall. Due to low flow temperatures, the system is extremely energy-efficient, responds quickly, and pairs perfectly with heat pumps or solar thermal energy.
• Additional benefits and a healthy climate: Because heat is transferred via radiation rather than convection, there are no air or dust swirls (a major benefit for allergy sufferers). A special bonus: In summer, the hydronic system can be converted into a silent, draft-free room cooling system.
A wall heating is the modern answer to the need for cozy, even warmth in your own home. As an invisible surface heating, it ensures a pleasant room climate over the wall surface – without radiators that take up space or stir up dust. Whether in new construction or during renovation in old buildings: Wall heating offers a future-proof, energy-saving solution for almost any home.
How does a Wall Heating work?
The wall heating uses the wall surface to emit heat into the room through radiation – making it one of the most comfortable systems. It creates an even, pleasant warmth. The heat is transported via heated water in heating pipes that are mounted over a large area in the wall. In contrast to classic convection heating, there are no air turbulences – this is particularly advantageous for allergy sufferers.
Water-guided Wall Heating
This variant is particularly energy efficient and is ideal for combination with heat pumps or solar thermal systems. Warm water flows through pipes located in the wall. It is durable, sustainable, and provides a particularly comfortable living experience.
A wonderful side effect: With water-based systems, cooling via the wall surfaces is even possible in summer – pleasant, quiet, and completely without drafts.
Electric Wall Heating
Electric wall heating systems operate with integrated heating mats or films. In practice, however, they are significantly less efficient than water-based variants. The power consumption is comparatively high, which can lead to considerable operating costs, especially in continuous operation. Additionally, an electric wall heating system cannot be used for cooling, making it less attractive as a long-term overall solution.
Laying Wall Heating - This is how it works
The installation depends on the chosen system: In drywall construction, the wall heating (a gypsum fiberboard with integrated pipes) is mounted on substructures. In plastered systems, the heating pipes are directly attached to the wall and covered with clay or lime plaster. The installation should be carried out by professional companies to ensure optimal heat distribution and efficiency.
One system - many advantages
With a Wall Heating from Variotherm, you choose a modern, energy efficient, and comfortable heating solution that can be optimally integrated into any home.
Wall Heating = wall cooling
With a Variotherm Wall Heating, you can create a pleasantly cool indoor climate even in the summer months. How? It's simple: By circulating cold water through your surface heating system. And just like that, your Wall Heating becomes a healthy and silent cooling system. Free from air and dust turbulence, quite the opposite of conventional air conditioning systems. In summer, it remains pleasantly cool, like in the shade of a tree.
Additionally, a surface heating/cooling system is invisible and leaves plenty of free space for ideas in interior design.
