1. A method for heating a liquid using a mobile liquid tank, the method comprising:
providing a liquid to be heated in a tank body, the tank body comprising a first heating element and a second heating element, wherein the first heating element is configured to be connectable to an external power source of low voltage and the second heating element is configured to be connectable, separately from the first heating element, to a mobile power source of extra-low voltage;
heating the liquid in the tank body to a predetermined temperature by the first heating element powered by the external power source;
maintaining the temperature of the heated liquid substantially constant by the first heating element when external power is supplied to the first heating element and maintaining the temperature of the heated liquid substantially constant by the second heating element powered by the mobile power source of extra-low voltage when external power is no longer supplied by the external power source;
measuring temperature data using a sensor in the tank body;
receiving the temperature data from the sensor on a control unit connected to the sensor; and
controlling regulation of the first heating element and the second heating element by the control unit using the temperature data as temperature input,
wherein the first heating element and the second heating element are connected to separate electrical connectors protruding from at least one external wall of the tank body, the separate electrical connectors are configured for connectability to external electrical connectors and are plugs spatially arranged in parallel,
the mobile liquid tank comprises the tank body, a first fluid path fluidly connecting a bottom of the tank body to a first fluid connector, and a second fluid path fluidly connecting a top of the tank body to a second fluid connector, wherein the mobile liquid tank is part of a system comprising a tank receiving device configured to receive the mobile liquid tank in a removable manner, wherein the tank receiving device comprises the control unit, the mobile power source, and at least one of the external electrical connectors, and a control valve for selectively connecting the first fluid path to an air pump or a liquid pump.
