A heat generator (1) comprises at least one thermal module (1′) which contains at least two adjacent magnetocaloric elements (2), and a common distribution chamber (3), associated with a heat transfer fluid circulation device (4), fluidly connects the adjacent magnetocaloric elements (2) with one another. Two end chambers (5, 6) are associated with a circulation means (7) and fluidly connected each with the two magnetocaloric elements (2) located at the hot end (9) and a cold (11) end of the thermal module (1). A magnetic arrangement of the heat generator (1) subjects each of the magnetocaloric element (2) to a variable magnetic field. The circulation mechanism (4), associated with the common distribution chamber (3), moves the heat transfer fluid simultaneously through the two adjacent magnetocaloric elements (2) in different circulation directions.
