A panel heater (2) comprises a metal casing (4) having respective spaced apart front and rear walls (6, 8) respective side walls (10, 12) and respective top and bottom walls (14, 16). The top and bottom walls include a plurality of slots (54) arranged in groups. A heating element is secured to the rear face of the front wall (6) and is arranged in operation to conduct heat to the front wall (6) which, in turn, radiates heat into a room in which the heater is disposed. Additionally, air can flow into the casing (4) via slots (54) in bottom wall (16) and over a rearwardly facing face of the heating element which heats the air. The heated air flows out of the casing, via slots (54) in the top wall (14), and into the room as convected heat. The construction of the heater (2) is arranged to maximise the transformation of electrical energy into thermal energy dissipated as useful heat within the room. |
