Embodiment Construction

[0029] Figure 1 shows a domestic water heater (or domestic water heating unit) 10 according to the present invention. The domestic water heater 10 has a domestic water tank 12 . The tank has a cylindrical basic shape and is arranged horizontally in the exemplary embodiment. The domestic water tank 12 has a domestic water inlet 60 on its lower side and a domestic water outlet 62 on its upper side. These inlets and outlets are located near opposite end faces of the cylindrical body (barrel), thus diametrically opposite each other. Domestic water 20 to be heated is accommodated in the domestic water tank 12 . The loss of thermal energy in the area around the domestic water tank 12 can be avoided by suitable thermally insulating (thermally insulating) walls 32 . At the center of the end face of the domestic water tank 12 adjacent to the domestic water outlet 62 is a counterpart of the flange connector 63 to which the flange connector 64 of the heat exchanger 14 is fastened by f...

Abstract

The invention relates to a domestic water heater (10) for mobile uses, which comprises a domestic water reservoir (12). The invention is characterized in that the domestic water heater (10) is provided with a fluid / domestic water heat exchanger (14). Thermal energy can be supplied to the fluid (16) by means of an additional heater and the thermal energy of the fluid (16) can at least be partially (20) transferred by the heat exchanger (14). The invention also relates to a method for heating water for domestic use.

Description

technical field [0001] The invention relates to a domestic water heater for mobile use with a domestic water reservoir. The invention also relates to a method for heating domestic water for mobile applications. Background technique [0002] Currently, in a motor home, household water is mainly heated using electric energy or gas as an energy source. Electric energy is a convenient, fast and safe heating option for stationary operation. However, electrical energy is usually only available at the corresponding connected power supply in a specific parking lot and is relatively expensive. Running an electrically controlled domestic water heating system from the on-board electrical network (typically a 12 volt system) does not provide sufficient buffer energy over long distances and is not very economical. [0003] Gas is relatively widely used as an energy source for heating domestic water. And the known disadvantages associated with this include the inability to always ensu...
