A horizontally located stationary drum supports a horizontally located rotor drum concentrically therewithin defining a relatively small annular space therebetween with a heat transfer fluid in said annular space. The rotor drum is rotated by a source of power thus generating frictional heat which is picked up by an air stream in a furnace type construction. In a further embodiment, the rotor drum is situated between an inner stationary drum and an outer stationary drum with annular spaces between the rotor and each of the stationary drums and with heat transfer fluid situated in each annular space thus increasing the heat generating capacity of the device.
