Prepare Your Boiler for Winter: Essential Checks & Tips – Storrington

Is your boiler prepared for the winter months?

When your boiler is working quietly in the background it’s easy to forget how essential it is. Yet when temperatures drop, a poorly prepared boiler can leave you without heating or hot water at the worst possible moment. This guide explains practical checks and simple maintenance steps to make sure your boiler is prepared for the winter months, helping to keep your home warm and comfortable.

Start with the boiler pressure

Boiler pressure directly affects performance. Most modern boilers have a pressure gauge with a green zone showing the normal operating range. Aim to keep pressure within that green zone — typically between 1 and 1.5 bar — because both low and high pressure can cause problems.

If pressure is too high, bleeding radiators can often help reduce it. If pressure is too low, you can repressurise the system using the filling loop. If the pressure keeps changing or cannot be corrected by these measures, get it investigated as soon as possible by an experienced heating engineer who is Gas Safe registered.

Bleed your radiators to remove trapped air

Air trapped in radiators creates cold spots and stops them heating efficiently. Bleeding a radiator is a straightforward DIY task: use a radiator key to release the trapped air and you should notice a difference in how they perform pretty much straight away.

Protect pipes from freezing

Frozen pipes are a common winter hazard. When a pipe freezes it prevents hot water from being sent to your taps and radiators. Two effective precautions are:

• Insulating exposed pipes in unheated areas.
• Keeping the central heating running during very cold spells so the system maintains temperature and reduces freezing risk.

If you plan to be away during cold weather, turn your thermostat down to low rather than switching the heating off completely, as this will still stop the temperature dropping to the point where your pipes are at risk of freezing.

Powerflushing

When radiators remain cold after bleeding, your system likely needs professional flushing. This specialised service removes accumulated debris and sludge that can impair your heating efficiency. At Pipeline Plumbing Services Ltd, we use advanced flushing techniques to restore your system’s performance without damaging your pipes or radiators.

Listen for unusual sounds

Your boiler should operate quietly and efficiently. If you notice any unusual sounds — perhaps a kettling noise or grinding — it’s crucial to have these investigated promptly. These sounds often indicate limescale build-up or pump issues, both of which can significantly impact your system’s efficiency during peak winter usage.

Run your heating system

We advise running your heating for at least 15 minutes every month during summer. This simple practice helps prevent pumps and valves from seizing up through lack of use. When autumn arrives, increase these test runs to identify any potential issues before they become serious problems.

Get your boiler serviced

The best thing you can do to prepare your boiler for winter is to get it serviced. By arranging a service towards the end of summer, a Gas Safe registered engineer can thoroughly inspect and check all the main parts of your boiler, and clean the inside to remove dust and debris which builds up over the year. A boiler service also allows for any emerging issues to be spotted and swiftly dealt with — preventing them from causing your boiler to need a full repair further down the line.
