The operating principle of the solution is that the energy in the continuous flow of used hot shower water (gray water) is heat exchanged with the continuously incoming cold water on its way to the shower mixer during showering. According to independent studies, this operating principle provides the best possible conditions for highly efficient energy recovery from shower and gray water.
Thus, connecting a bathtub shower to the Enduce floor drain will work, provided you can access and open the floor drain strainer for cleaning. However, if no cold water is used by the shower mixer, no energy can be recovered when draining the bathtub water.
