Do gas fires use more gas than central heating?

( ratingratings)

In the majority of cases heating your whole home with gas central heating can be more efficient than heating one room with a gas fire. This is especially true if you have a room thermostat which turns off your heating when the temperature reaches the correct level.

You can check which is cheaper for you by doing this comparison test:

Step 1 – Test your gas fire

  1. Take a gas meter reading – mark it ‘gas fire reading 1’.
  2. Put your gas fire on for a set amount of time, let’s say 2 hours. Do this at a time when you don’t need to use any other gas-powered appliances.
  3. When you’re done take another gas meter reading – mark it ‘gas fire reading 2’.
  4. Take away ‘gas fire reading 1’ from ‘gas fire reading 2’ and make a note of the number, marking it ‘gas fire difference’.


Step 2 – Test your central heating

  1. The next day take a new gas meter reading – mark it ‘central heating reading 1’.
  2. Put your central heating on for the same amount of time you put the gas fire on the previous day, again at a time when you’re not using any other gas-powered appliances.
  3. When you’re done take another gas meter reading – mark it ‘central heating reading 2’.
  4. Take away ‘central heating reading 1’ from ‘central heating reading 2’ and make a note of the number, marking it ‘central heating difference’.


Step 3 - Compare

Compare the ‘gas fire difference’ and ‘central heating difference’ numbers. Whichever one’s larger is costing you more.
