[0004] EP0332038 discloses a heating system for heating both the air surrounding an enclosure containing the heated body of the heating system and the water, in which an air / water heat exchanger is provided. The chamber of the system described in EP0332039 comprises two hot air circuits I and II, the circuit I being in direct contact with the heating element. In a hot water production mode, a fan is used to suck the hot air through an air / water heat exchanger, and to switch on the fan also to open a flapper. allowing the air to circulate according to the closed circuit I. In this mode, the heat transfer from the circuit I to the circuit II is only possible via a wall separating these two circuits. warmed The water thus circulates in closed circuit in the circuit I in the hot water production mode. In a hot air production mode, the fan is de-energized and the valve mentioned above is closed. On the other hand, two other valves are then open allowing an increased heat transfer other than the air circuits I and II. Finally, two openings respectively allow to capture the colder air surrounding the heating system and to reject hot air outside the enclosure in the hot air production mode.

In this last mode, the heat transmission to the outside of the enclosure is ensured by natural convection because the fan is at ramftt. At the same time, the cold external air penetrating through the openings to the circuit I must topple the air / water heat exchanger to come into contact with the heating body, thus cooling the water circuit. Such a system also requires the presence of different valves within the fencing of the heating system, the replacement or maintenance of such non-accessfeles elements from outside is not easy. Finally, such a system offers two exclusive modes of operation: air heating or water heating.
