Abstract: A domestic electric heating system (100) comprises a main electrical power feed (104) connected to distribution means (102). The distribution means (102) allows electrical power to be switched via power connections (110, 120, 130, 140) to heaters (111, 121, 121, 141), each located within a separate room or area (115, 125, 135, 145) of the domestic dwelling. Control means (101), contains processing means (105) configured to allocate the available electrical power from the power feed (104) in accordance with distribution parameters entered by use of input means (103). The power used is reduced by only distributing power to a limited number of the heaters (111, 121, 131, 141) at any one time. The power can be distributed proportionally between heaters (111, 121, 131, 141) by distributing power to certain of the heaters in turn according to a cyclical sequence.
