Whether in new construction or renovation: Wall cooling ensures pleasant temperatures in summer – quiet, efficient, and invisible. Unlike conventional air conditioning systems, it cools evenly and without drafts. The result: a natural, comfortable indoor climate. Variotherm offers a sustainable solution with its water-based wall cooling system for those who want to combine living comfort with energy efficiency.

A wall cooling uses water as a cooling medium. Pipes are laid in the wall through which cool water circulates. The heat in the room is absorbed by the wall and dissipated outside – without fans, drafts, or noise.

The effect is pleasant: The room air remains dry and evenly cool, and the climate feels natural.

Water is the ideal energy carrier: It can efficiently absorb and transport heat. In the Variotherm wall cooling, cold water is channeled through a pipe register in the wall. This surface radiation removes excess heat from the room – without any noticeable air flow.

Especially in combination with a heat pump, the system becomes particularly efficient and environmentally friendly.

The wall cooling is a water-guided surface system that is directly integrated into the wall. Cooled water flows through the pipes. These surfaces do not emit cold air, but rather pleasant radiant cooling – completely even and draft-free.

Depending on the construction situation, Variotherm offers two solutions:

Drywall Construction Systems (gypsum fiber boards with pre-integrated pipes)

Plastered Systems (rail system with pipes)

Both variants are energy efficient, silent in operation, and almost maintenance free. Especially in combination with a heat pump, the system operates energy efficiently – and climate-friendly.

The installation of wall cooling is simple and efficient – especially with the pre-configured systems from Variotherm. Depending on the construction method, either drywall construction elements or plasterable pipe modules are used.

Installation in 3 steps:

1.  Installation on the wall – e.g., gypsum fiber boards or pipe rails on plaster base.
2.  Connection to the manifold – the pipes are connected to the central system.
3. Plastering or filling the surface – ready for interior finishing.

Wall cooling is suitable for all rooms where pleasant temperatures are desired in the summer - without any disturbing noises or air movement. They are particularly popular in:

- Living rooms & bedrooms
- Offices & home offices
- Hotels & holiday apartments
- Passive and low-energy houses

In winter, it heats, in summer, it cools - with one and the same system.

Like any system, wall cooling also has its limits – here are the most important ones at a glance:

- Planning required: Installation must be planned early, especially in drywall construction or during renovations.
- Space requirement: To ensure sufficient cooling performance, enough wall space must be available – furniture or built-ins can reduce performance.

Conclusion: With good planning, the advantages clearly outweigh the disadvantages – especially in high-quality construction projects with a focus on comfort, sustainability, and design.
