Heating your home during the cold months might seem like a long way off, but looking after your boiler now can help reduce problems through the winter.

We highly recommend preparing for the chill by turning your heating on while the weather is still relatively mild. You don’t need to use it for long - just enough time for your radiators to warm up.

To make sure that everything is running smoothly with your boiler and radiators, take a look at our advice to some common issues and how to resolve them.

 

Make sure the thermostat is set correctly with summer and winter settings.

Due to warmer weather, the thermostat may need setting higher than normal to activate your heating.

The amount of water in a boiler and central heating system is indicated on the pressure gauge, and this should be between 1 and 1.5 bar.

When a central heating system hasn’t been used for a few months, the amount of pressure in the boiler and central heating system can drop. This can often cause a boiler to stop working and will show as an error code on the display (Vaillant - F22, Potterton - E119, Intergas - 0.0).

To replace the water and increase the pressure, turn the taps on the chrome flexible pipe (filling loop) shown. The taps on the filling loop can only be turned one way. When turned you should hear water filling the system and notice the pressure in the boiler begin to rise. 

Aim for between 1 and 1.5 bar, or the green section on pressure gauge, then turn the taps back and you will hear the water stop. This will fill the system with enough water and remove the error message. Your boiler should be working normally after about 20 minutes.

Here are some Top Tips for making sure your boiler is in the best working condition:

  • If your gas meter is pre-paid, make sure you have enough credit on it
  • Check all your other gas appliances are in full working order
  • If the unit has a fuse switch, check the switch is pressed down
