Night Storage Heaters Electricity Cost Calculator
Night storage heaters use electricity supplied at cheaper off-peak night time tariffs (Economy 7 and Economy 10). Storage heaters radiate heat stored during the night slowly releasing this heat the following day.
Storage heaters are rated in Watts (W) or Kilowatts (kW). Check what your heaters are rated at, then use our energy calculator to see how much each heater should cost to run per hour, day or week.
