Winter Advice

If you're unprepared for a cold, harsh winter then you could be putting yourself at risk of frozen pipes, boiler problems and unexpected bills. Following our winter advice can ensure that your home stays warm and your heating stays efficient during the cold months.

Bleeding your radiators

Over time, it's common for your radiators to develop air pockets. Without treatment, these air pockets will mean that your heating doesn't work as efficiently as it should and can eventually cause issues with your boiler. Bleeding your radiators releases the trapped air which lets water to flow properly through your heating system, releasing more warmth into your home. The tell-tale signs of a radiator that needs bleeding are taking too long to heat up and cold spots on the top of the radiator.

Bleeding your radiator is a simple but effective job. Find out how to bleed your radiators in our step-by-step guide here.

Getting your boiler serviced or replaced

It's important you have a boiler that is going to get you through the winter without any problems. If you have a new/modern boiler, make sure you get your annual service done before winter to make sure it's running properly. If your boiler is a few years older, having a service before the winter months hit will spot any potential problems your boiler is facing and fix them before it is put under any extra pressure. Remember, if you take care of your boiler it will take care of you. To book a service, call 0344 871 1545

Older standard efficiency boilers are less efficient than modern condensing boilers and will cost you more to run during winter. If you want to keep bills down long-term and reduce the chance of any potential problems, consider a new boiler.

Condensate pipe home maintenance

If your boiler has been installed with the plastic condensate pipe on an outside wall, the liquid inside the condensate pipe could freeze if the temperature drops below zero. If this happens, the boiler will shut down to protect itself and you will see the error code E133 on its display panel. The display will alternate between E1 and 33.

To get your boiler back up and running again without having to call an engineer, follow these simple steps:

  • To unfreeze the pipe, pour hot, but not boiling, water across the length of the plastic pipe until it has defrosted. This could take around 30 minutes, but the boiler will not light until the pipe has cleared.
  • Once the pipe has thawed out, you will need to reset the boiler, and it should then fire up and run as normal.

If the error code still displays once the pipe has thawed, contact a Gas Safe registered engineer or call Baxi Customer Support on 0344 871 1545. To help prevent your condensate pipe or any other cold pipes in your home from freezing lag them with pipe insulation, it is relatively inexpensive and could help you avoid any blockages or bursts that are caused by freezing.

Water pressure checks

If the pressure in your heating system drops your boiler could shut down, You will need to repressurise your boiler, so it's important you check the pressure indicator regularly. To check boiler pressure, use your boiler's user guide to find the pressure gauge then make sure it is between 1.0 bar and 2.0 bar.

To repressurise your boiler yourself using either a Flexible Hose Filling Loop or Rigid Filling Loop, see our step-by-step video guides:

If you have any other concerns regarding your boiler pressure we advise you to contact a Gas Safe registered engineer or Baxi Customer Support.
