However, since it takes some time to install a water heater and to be able to supply hot water, it was not sufficient as an emergency measure. In addition, it was only possible to respond on a small scale, and it ended up being a temporary response.

  As a disaster response, it is not sufficient to be able to cook for disaster victims in emergency evacuation areas, etc., and it is desirable to be able to supply hot water and electric power together, but to supply them The actual situation is that emergency facilities are not always available.

  The technique of Patent Document 1 supplies power and water using an existing cogeneration system, and has a limit that it is limited to an area where such a cogeneration system is installed. In addition, the technology of Patent Document 2 considers the supply of fuel gas to individual consumers, and is an urgent need to supply fuel gas to people gathered at specific locations such as evacuation sites during a disaster. Was not suitable. Furthermore, in the event of a disaster, not only the supply of fuel gas but also the supply of hot water is required, but the hot water supply equipment has not been considered.
