Thermodynamic boiler with thermal compressor

A thermodynamic boiler for exchanging heat with a heating circuit, the boiler comprising:

• a thermal compressor, the thermal compressor acting on a compressible fluid and comprising a first compression stage, with an alternating bi-directional piston separating a first chamber and a second chamber, and a first fuel burner forming a heat source coupled to the first chamber, the heating circuit being a cold source coupled to the second chamber, the thermal compressor forming a compression function of a reversible heat pump loop,
• the first and second chambers being fluidly connected between each other through a regenerator with a to-and-fro fluid movement.
