oil filled radiator cost to run?

best answer
  • For example a 2KW oil filled radiator that is in use for 5 hours per day will use a maximum of 10 units of electricity per day. 2 (KW) X 5 (hours) = 10 (units of electricity) If you pay 34p per unit for electricity the maximum cost of running your 2KW radiator for 5 hours per day will be £3.40.
