Abstract: A double-circuit electric boiler comprises a power supply system, control elements, a housing (5) having inside a container (1) for water of a hot water supply circuit and a container (2) for a heat¬ carrying agent of a warming circuit with electric heater (3). The container (2) is mounted inside the container (1). One of surfaces of the container (2) is an outer wall (7) that is disposed and secured outside the container (1). An inner surface (29) of the outer wall (7) is in contact with a mounting wall (16) of the container (1). An outer surface (30) of the outer wall (7) is disposed outside the container (1). The outer surfaces of inner walls (6) of the container (2) are in contact with the water of the hot water supply circuit inside the container (1). The at least one electric heater (3) of the heat-carrying agent of the warming circuit is fully isolated by the inner walls (6) of the container (2) from a contact with the water of the hot water supply circuit. The outlet duct (8) for the container (2) and the inlet duct (9) into the container (2) are secured in technological openings of the outer wall (7) of the container (2), and their end openings are coupled to the corresponding technological openings of the container (2) inside the container (1). An outlet duct (10) for the container (1) and an inlet duct (11) into the container (1) are disposed inside the container (1) and fully isolated by the inner walls (6) of the container (2) from a contact with the heat-carrying agent in the container (2). Inside the container (2) there is mounted a temperature sensor (12), which is fully isolated by the inner walls (6) of the container (2) from a contact with the water in the container (1). And inside the container (1) there is mounted a temperature sensor (13), which is fully isolated by the inner walls (6) of the container (2) from a contact with the heat-carrying agent in the container (2).
