摘要： A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.
