The Basics of Gas Fire Energy Consumption

Before diving into the calculations, it’s important to grasp some basics. Gas fires are measured in kilowatts (kW), and their consumption is typically billed in kilowatt-hours (kWh). Knowing the input rating of your gas fire (in kW) is the first step to understanding its running cost.

Step-by-Step Gas Fire Running Cost Calculator

  1. Identify Your Gas Fire’s Input Rating: Check the manual or look for a label on your gas fire to find its input rating in kilowatts (kW).
  2. Find Out Your Gas Tariff: Check your energy bill or contact your supplier to find out how much you’re paying per kilowatt-hour (kWh) for gas.
  3. Calculate Hourly Running Cost: Multiply the input rating of your gas fire by your gas tariff. For example, if your gas fire has an input rating of 5kW and your gas tariff is 5p/kWh, your hourly running cost would be 25p.
  4. Estimate Your Monthly and Annual Costs: Consider how many hours a day you use your gas fire on average and multiply this by your hourly running cost. Then, multiply this by the number of days you typically use your gas fire in a month or a year to estimate your total running costs.
