The convector heater has a housing accommodating an electric element, and openings in the top and bottom for the convection air. An axial-flow-fan with the element is mounted in the housing and discharges via an opening in the side of the latter. The fan rotor is enclosed in an air guide tube extending part-way into the housing and secured to a ventilation grille fitting over the side opening edge. |
