<p>A mobile power washer includes a heater module that is displaceable from an operative position, beneath a vented panel, to an access position enabling easy servicing or replacement of the module. The module includes a heater and a heat exchanger for heating water drawn from tanks for delivery at high pressure through a spray gun attached to a hose. A buffer tank is provided for retaining water heated by the heater for mixing with cold water from the tanks prior to further heating in the heat exchanger and delivery from the spray gun.</p> |
