The invention concerns a boiler comprising juxtaposed exchanging elements (1) provided at their opening (10), with a thermostatic valve (11). This valve (11) is closed when the temperature of the fluid in the boiler is lower than a pre-programmed reference input value. A thermostatic valve (11) can be arranged in each exchanging element (1) for autonomous regulating of the flow rate of each of said elements. |
