An electrically powered space heating device comprises a housing arranged to dissipate heat generated therein to a space in which the device is located. The housing contains means defininga flow path for a fluid within the housing, fluid flow means for causing fluid to flow in said fluid flow path, and an electrically powered heating means (12) for heating fluid flowing in said fluid flow path. The housing is substantially made of metal. The housing is arranged to dissipate heat generated therein by convection; thermal transfer from the housing is assisted by means of a multiplicity of convector elements or fins (5) forming a convection airflow path through an/or around the device. The electrically powered heating means is arranged adjacent a side wall (4) of the housing. The electrically powered heating means comprises a heatable body and conduit means associated therewith for the flow of fluid over the heatable body. Preferably the conduit means forms part of the fluid flow path and the conduit means defines a convoluted fluid path around the body for the transfer of heat from the heatable body to fluid flowing in the conduit means.
