The floor heating has a kink after the repair!

The bending of the heating elements, as shown in the photos, is completely insignificant from a heating technology perspective. Whether the heating elements are embedded in the concrete or in the lower screed cross-section: the heating elements can also tolerate smaller bending radii. What happens is that with many bends/changes in direction the internal pressure increases. But this is also completely insignificant, as the heating engineer performs the hydraulic balancing. This compensates for the internal resistances that inevitably and unavoidably occur in different heating circuits! So: please relax again!
