A method of electrically heating spraying media in hand spray appliances, flow heater and other atomizers comprises the spreading out of the medium into a thin film-like stream before or during the heating in order to obtain rapid absorption of heat. In Fig. 1 spray medium flows as a film between the heated base A of a reservoir B and a baffle C to a spray gun. The reservoir may be arranged below the gun. In a flow heater type atomizer a baffle C, Fig. 3, directs the medium as a film onto the heated part A. Grooves or spirals may be arranged on the baffle or heated surface to increase the spray medium path. An automatic control of the heating is described in which the heating current is switched on only when atomizing gas is fed to the appliance, and the heating is then controlled by a thermostat switch.
