A radiator in particular for room heating, comprising a control or measurement unit accommodated in a container integral with the radiator and positioned so as to sustain the heat from the radiator as little as possible, while exploiting a cool air flow drawn by the same to cool the internal circuitry defining the unit. Said container is conveniently spaced apart from the radiator by means of insulating elements and a part of the same container is formed by a heat dissipator to which one or more electronic power elements included in said circuitry are thermally connected.
