Background

The use of hot water and/or steam is commonly required in applications such as garment ironing, fabric finishing and sizing, the use of adhesives, food production, biomedical production, dish disinfection, sauna, winter heating, and vehicle cleaning, among others. For example, the cleaning of the interior of a vehicle, which typically does not allow the use of water but should be carried out with steam, a miniature dual-purpose steam-water boiler with good mobility would undoubtedly be favored by the car wash industry.

In view of the foregoing, there is a need for improvement, and the technical solutions described below are made in this context.
