Ways to cut the cost of running a electric fireplace

  • Use it less at peak times if you are on a time-of-use tariff, and more when power is cheapest.
  • Choose a model with a high energy rating when you replace it. The saving over its life is often bigger than the price difference.
  • Switch it off at the wall when it is not in use if it has a standby draw.
  • Check your tariff. A lower unit rate cuts the cost of every appliance in the house.
