Storage charging assembly

The storage charging assembly is available in different versions. The components are already pre-assembled on a platform which can be installed directly on the x-buffer layered buffer storage unit and which is supplied with the corresponding insulation. Alternatively, the pump group can also be used for wall installation. A switchover valve ensures a switchover between domestic water heating and room heating.
