Switch off the gas boiler or leave it on? Simply explained

by Johannes

Whether you should switch your gas boiler off or leave it on depends on various factors. Often you can already find important information in the operating instructions that will help to extend the service life of the gas boiler and avoid possible problems.

When you should start or turn off your gas boiler

If the following things apply to you, it is better to leave your gas boiler on and not turn it off:

  • When it is very cold outside, it is usually better to leave the gas boiler on.
  • This will ensure that the house is kept at a comfortable temperature.
  • Also consider the times when you are out of the house. If you are only ever away for short periods of time, it may be better to leave the gas boiler on to prevent the house from getting too cold.
  • Along with this, consider whether you might want to install a timer.
  • A timer can make the gas boiler turn on and off at certain times so you don’t have to manually intervene every time.

In these situations you should switch off the gas boiler

In some situations, it makes sense to turn off the gas boiler.

  • This applies, for example, when the outside temperatures are higher. Then it makes sense to switch off the gas boiler to save both money and energy.
  • Even if you are going to be out of the house for a long time, it can make sense to turn off the gas boiler to save energy.
  • This applies, for example, when you are going on holiday or on a business trip.
  • If you notice that your energy bills are unusually high, it might be a good idea to turn off the gas boiler when it is not needed to save money.
  • Sometimes you will also find specific instructions in the user manual of your gas boiler about when the gas boiler should be turned on and off.
