The Variotherm SystemWall and the EasyFlexWall are clever solutions all-round. They are heating and cooling systems in one. In the winter, they provide wonderfully cosy radiant heat. In summer, when cold water circulates through the SystemWall or EasyFlexWall (e.g. via a heat pump) they are wall cooling systems with excellent cooling capacities.The Variotherm SystemWall guarantees a particularly pleasant room atmosphere, as the components have been tested and approved by the Austrian Institute for Healthy and Ecological Building (IBO quality seal).
