Compared to systems with vertical ground heat exchangers, this concept is significantly more cost-effective. however, as frost protection of the slab has to be guaranteed it works only with restrictions. You can prevent the ground from freezing either by reducing the inlet temperature or by lowering the heat pump's power. For more details download the CAD file from our cadbull site. This can be used by architects and engineers. Download this 2d AutoCAD drawing file.
