The insulating layer is intended for laying on a floor and the heating element extends between the cladding and the insulating layer. The cladding is intended to support a floor covering and comprises a force distribution layer for transmitting a force which is exerted on the cladding in a distributed manner to the insulating layer. In as far as (a part of) the heating element is at the location or in the vicinity of the exerted force, the load which will be exerted on it will be lower than the original load, due to the force being transmitted in a distributed manner. This lowers the risk of the heating element being damaged.
