A portable steam-producing apparatus is disclosed. Methods of making and using portable steam-producing apparatus are also disclosed.

A heating system is connected to a source of supply fluid to be heated, and has an internal combustion engine provided with engine coolant and gases that flow to and from the engine, and are heated thereby. A heat generator is provided in fluid communication with a supply of heat transfer fluid for circulating the heat transfer fluid in the heat generator causing fluid friction to create heat directly in the heat transfer fluid, and provide heated transfer fluid that is not in fluid communication with the engine. A fluid heat exchanger arrangement is provided in fluid communication with the supply fluid, the engine coolant, the gases of the engine and the heated transfer fluid for transferring heat from the heated engine coolant, the heated engine gases, and the heated transfer fluid to heat the supply fluid.

A portable thermoshapable fabric composite heating device kit mainly comprises a portable heating device and a thermoshapable fabric composite; wherein the portable heating device includes a first box body and a second box body disposed above or inside the first box body. A heating space formed between the bottoms of the two box body bodies is used to accommodate a heating pack. The thermoshapable fabric composite can be accommodated within a receiving space of the second box body. After water is added into the first box body to flood the heating pack, and a lid is placed to cover the top, the heat-generating material in the heating pack contacts the water to generate water vapor during an exothermic reaction. The water vapor enters the receiving space, in which the thermoshapable fabric composite is stored, through the multiple pores at the bottom of the second box body. The generated thermal energy will heat the thermoshapable fabric composite without the need for open flame or electricity. That is, the thermoshapable fabric composite can be heated and softened, so that the thermoshapable fabric composite can be used in the field without reliance on external elements, such as conventional heating or electricity, in order to achieve the purpose of providing first aid such as bandaging and fixation, and to prevent secondary injuries.

A water supply system includes a main water tank that is configured to store water and includes a heater to heat the stored water to close to but below a boiling temperature thereof, to provide main heated water. A dispenser water tank receives a portion of the main heated water, and is free of any heating elements to add heat to the water stored therein, and providing dispensable heated water. A water mixer includes a first pipe for receiving the dispensable heated water from the dispenser tank and a second pipe for receiving utility water from a faucet that supplies utility-provided water, with a mixing chamber from which the waters from the first pipe and the second pipe are dispensed and/or in which these waters are admixed.
