Keep your boiler running with simple tips. Check pressure, bleed radiators, insulate pipes, and know when to call.
Keeping your boiler well-maintained is one of the simplest ways to avoid unexpected breakdowns, high energy bills, and costly repairs. By taking a few easy steps at home, you can keep your system running efficiently and ensure your family stays warm throughout the year.
Your boiler relies on the right level of pressure to function properly. Most systems should sit between 1 and 1.5 bar when cold, which you can see on the pressure gauge at the front of the boiler. If the pressure is too low, you may notice poor heating performance, radiators not warming fully, or a complete lack of hot water. You can usually top it up yourself by opening the filling loop valve until the gauge rises to the correct level. If the pressure continues to drop regularly, it could signal a leak or an underlying issue, and it’s best to call a heating engineer.
Cold spots on your radiators usually mean trapped air in the system. This makes your heating work harder and pushes your boiler to burn more fuel than necessary. By using a radiator key to slowly release the air, you’ll notice more even heating and lower energy usage. Place a cloth underneath to catch any drips of water, and start with the radiators furthest away from the boiler for best results. If you find yourself bleeding them often, it may point to a bigger issue with the system’s balance or pressure.
Frozen pipes are one of the most common causes of boiler shutdowns in winter. Condensate pipes, often found outdoors or in unheated areas, are particularly vulnerable. Adding inexpensive pipe lagging helps prevent freezing and keeps your system running smoothly during cold weather. You can buy foam insulation sleeves from most DIY stores and fit them easily yourself. For added peace of mind, ask a professional to check pipework insulation during your annual boiler service.
Your boiler needs space to breathe and must have good ventilation to operate safely. If it’s kept in a cupboard, avoid stacking items around it that could block airflow or restrict access for servicing. Make sure nothing is covering the boiler or blocking the flue outside, as this could lead to dangerous carbon monoxide build-up. Keeping the area tidy also makes it easier to spot any leaks, drips, or warning lights on the boiler itself.
Even in the summer months, it’s a good idea to run your heating system for 10–15 minutes once a month. This keeps the boiler components moving and prevents them from seizing up after long periods of inactivity. It also gives you the chance to pick up on small issues before the colder months arrive, saving you from the stress of emergency repairs during winter. Think of it as a quick warm-up for your boiler to stay in working order.
While routine checks are helpful, nothing beats the reassurance of a professional boiler service. An annual service carried out by qualified heating engineers in Cheddar, Weston Super Mare, and Clevedon ensures your boiler is safe, efficient, and compliant with current regulations. During the service, an engineer will clean internal parts, check for carbon monoxide leaks, test safety devices, and identify worn components that could cause future issues. Skipping services can void warranties, so keeping up with them protects both your boiler and your pocket.
Your boiler will often give small signals that something isn’t right. Strange noises such as banging, gurgling, or whistling can indicate trapped air, limescale build-up, or failing parts. Water leaks or damp patches around the boiler are always a red flag and should be addressed immediately. Strange smells, frequent pilot light failures, or error codes on the display are also signs that professional attention is needed. Acting quickly on these warning signs can stop minor problems from turning into costly breakdowns.
