A fuel-operated vehicle heater especially of the type intended as an auxiliary or additional vehicle heater and which has a nozzle sitting on a nozzle holder to which fuel is fed from a fuel line by a filter, a fuel pump and an interposed solenoid valve. In a preferred embodiment heater, the nozzle holder, fuel pump, filter and solenoid valve form a subassembly that can be handled as a single unit. Advantageously, this subassembly can be fastened by screws to a flange within a housing part of the heater. On this flange can also be fastened an ignition spark emitter an a central connecting device, such as a burner motor. Advantageously, the feed line and/or the return line for the fuel supply are formed in the flange.
Fuel-operated vehicle heater having an atomizing burner, an atomizing nozzle carried by a nozzle holder, a fuel pump for delivering fuel to the atomizing nozzle via a filter and an interposed solenoid valve, and a combustion air blower driven by a drive motor, wherein the nozzle holder is in the form of a housing by way of which the heater components comprised of the atomizing nozzle, the fuel pump, the filter and the solenoid valve are combined into a unified subassembly carried by said nozzle holder as a single unit.
