The invention relates to a heat retention system for keeping warm meals by way of converting induced electromagnetic energy of arisen heat. The system contains a receptacle (5, 55, 103) with passive elements (3, 53) which via a plate (9, 59, 209) are in active connection with active elements (2, 210). Sensors (16, 18, 56, 215) and an optimised control unit (212) control and regulate the temperature of the meals (8) located in the receptacle (5, 55, 103), so that these are not cooked and energy is supplied in a directed manner. Preferably the heat retention system is configured as a heat retention device which has a modular construction and may be dismantled into individual modules (101, 102, 103, 104) and may be assembled of individual modules (101, 102, 103, 104). For this the individual modules comprise fastening means (105-108, 126, 135, 138, 145-148, 155, 158), preferably turnbuckles (155, 158) or positive-fit fastening means (105-108, 126, 135, 138, 145-148) which correspond to the fastening means of further modules.
