Contact us nowWhat is concrete core activation?
In concrete core activation (also known as concrete core temperature control or thermal component activation), pipes are located in the floor and ceiling slabs of buildings. These function as heating surfaces and, due to their size, manage with very low flow temperatures.
What does concrete core activation cost?
Roughly speaking, you can expect costs of between 45 and 65 euros per square meter to be heated. If the heat is then to come from a solar thermal system, the corresponding costs must also be factored in
