ABSTRACT:
A convector heater has a front plate 1 with a surround 2 spaced around the periphery of the front plate 1 so as to define a top, bottom and side air gap 3 between the front plate 1 and the surround 2. A back plate 4 is connected at its periphery to the surround 2 and is spaced from the front plate 1 so as to define a convection air space 7 between the front plate 1 and the back plate 4. The convection air space 7 is open to the surrounding atmoshere at the air gap 3. A heat exchanger, such as an electric heater, is disposed at the bottom of the convection air space 7 for heating air to induce a convection air flow through the convection air space 7 from the bottom air gap 3b to the top air gap 3a. A secondary air flow is induced into the air space 7 through the side gaps 3c, 3d by the main convection air flow. A control means is so disposed at a top corner of the convection air space the the air impinging on said control means includes air from said secondary air flow entering through the respective side air gap portion and is cooler than the primary convection air flow leaving the top air gap portion.
