winter Boiler Breakdowns
Avoid Winter Boiler Breakdowns: Local Tips from MyBuild Renewables & Plumbing Ltd
When the cold weather hits Portishead and the wider Bristol & North Somerset area, our phones start ringing non-stop. Winter boiler call-outs surge every year — and it’s rarely at a convenient time. Frozen mornings, family gatherings, Christmas holidays… boilers always seem to choose the worst moment to stop working.
At MyBuild Renewables & Plumbing Ltd, we’re your local Gas Safe registered heating experts, and we’ve seen every winter heating emergency there is. The good news? With the right preparation, most boiler breakdowns can be avoided.
❄️ Why Boilers Fail More in Winter
When temperatures drop, your boiler and heating system work much harder. Common winter breakdown causes include:
Frozen condensate pipes
Low system pressure
Sludge build-up in heating systems
Worn or seized components
Faulty pumps and valves
Lack of annual servicing
Even a small issue ignored through summer can become a costly problem when the cold arrives.
🔥 Early Warning Signs to Watch For
Act fast if you notice:
Radiators heating unevenly or staying cold at the top
Boiler pressure dropping below 1 bar
Strange noises — banging, gurgling, whistling
Frequent resets or error codes
Higher-than-usual energy bills
Hot water temperature fluctuations
Catching issues early = fewer emergency call-outs and lower repair bills.
🛠️ How to Prevent Winter Boiler Call-Outs
Our top engineer-recommended tips:
✅ Book your annual boiler service
A properly serviced boiler runs safer, more efficiently, and lasts longer.
✅ Bleed radiators & check system pressure
Keeps your heating running smoothly and evenly.
✅ Insulate your condensate pipe
Stops it freezing in sub-zero temperatures.
✅ Consider a system flush if radiators are slow or patchy
Removes sludge and helps your boiler circulate heat properly.
✅ Test your heating before you really need it
Run your heating once a week in autumn for 15 minutes.
🧯 When to Call a Professional
If you have:
A gas smell
Frequent pressure drops
No heat or hot water
Persistent fault codes
Frozen pipes you can’t safely thaw
Stop, turn the boiler off, and call a Gas Safe engineer immediately.
