A heat retention system for keeping meals warm by 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) regulate the temperature of the meals (8) located in the receptacle (5, 55, 103), so that these meals are not cooked and energy is supplied in a directed manner. Preferably, the heat retention system is configured as a heat retention device that 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 include fastening devices, (105-108, 126, 135, 138, 145-148, 155, 158), such as turnbuckles (155, 158) or positive-fit fastening means (105-108, 126, 135, 138, 145-148) that correspond to the fastening devices of further modules.
