The heating system comprises a plurality of groups G1-GN of one or more radiating panels 2. Each panel includes a slab of material 3, preferably ceramic, and a resistive heating element 4. Each of the groups is connected in parallel with an electricity supply line 5 and is controlled by a respective electronic switch T, preferably a TRIAC, which selectively couples the group to the supply line. An electronic control unit (ECU) is arranged to control the switches so as to couple one or more of the plurality of groups to the supply line for a period of time sufficient to bring the panels to a predetermined temperature and subsequently couple one or more of the plurality of groups to the supply line when a temperature measured by a temperature sensor 7 associated with the group falls below a predetermined threshold. A visual signalling device 8 such as coloured LEDs may be used to indicate to a user which groups are coupled to the supply line. Each panel may include hooks (18, figure 2) or other attachment means to attach the panel to a wall. |
