An aircraft having an engine, a dihydrogen tank, devices to be heated, a first air intake for taking in air at a low pressure or at an intermediate pressure, a second air intake for taking in air at a high pressure, a first heat exchanger, a first pipe which passes through the first heat exchanger and feeds the devices to be heated. Upstream of the first heat exchanger, the first pipe is divided into two sub-pipes connected respectively to the first air intake and the second air intake, and a fuel pipe that is connected between the tank and the combustion chamber and passes through the first heat exchanger. The use of heat exchangers on the dihydrogen pipe allows a regulation of the temperature of the devices to be heated and of the engine and to increase the temperature of the dihydrogen before its combustion.
