The water boiler has water jacket reduced with respect to the body of the boiler and separated in horizontal direction to two û ten insulated chambers connected in sequence in such way that the branch pipe for cold water supply is connected to the upper insulated chamber. The outlet branch pipe of the chamber is in its turn connected to the inlet branch pipe of the insulated chamber placed under it. In the lower insulated chamber over the inlet branch pipe the branch pipe for hot water export is placed, at that the lower heat exchanger goes with its ends to the cavity of the lower insulated chamber.
