Abstract: An automobile temperature control system has a motor chamber on which a secondary cell or a fuel cell is mounted for driving wheels by a motor and a cabin and controlling a temperature of portions of the automobile. The temperature control system includes at least one catalytic heater and a fuel tank. The catalyst heater generates heat when an oxidizing gas and fuel from the fuel tank are supplied to the catalyst. At least part of the gas supplied to the catalyst and heated by the generated heat is subjected to circulative supply to the catalyst. The temperature of the portion of the automobile is controlled by using heat generated by the catalytic heater. As a result, a system is provided that efficiently controls the temperature of a portion of the automobile so that performance deterioration is prevented and comfortable running is realized even in a cold region.

Abstract: A compact vehicle heating system and method is provided which includes mechanisms to selectively shut down heating systems. For example, when domestic hot water is required, space heating and engine preheating systems can be shut down in order to provide priority heating to the domestic hot water. When the demand for domestic hot water is lower, the space heating and engine preheat systems can be reactivated.

Abstract: A heater of a motor vehicle is provided which is operated with liquid fuel. The heater is especially a water heater in the form of an auxiliary heater or parking heater. The heater has a burner and heat exchanger in a housing with a cover, in which the connecting branches for the water feed and air feed and for the water return and the air return are arranged. At least one of the connecting branches is designed as a rotatable elbow branch (rotatable elbow socket). An antirotation lock may be provided for easy individual line guidance requiring little space in the automobile.

Abstract: A wind deflector shield for the ventilation opening in the door of a water heater closet of a vehicle. The deflector shield is resiliently flexed to install the shield in the ventilation opening.

Abstract: An attachment for a recreational vehicle of a type having a gas-fired hot water heater inside and having an exterior skin therearound. The hot water heater includes a burner and a vent for permitting outside air to communicate with the burner of the hot water heater. A rigid wind guard is operatively and removably attached to one side of the vent on the outside of the recreational vehicle for preventing wind from blowing out the burner when such burner is operating.
