❄️ WINTER HEATING TIPS – KEEP YOUR HOME WARM & YOUR BOILER HAPPY! ❄️
As the cold weather sets in, we see the same common boiler issues popping up — but the good news is, many of them are easy to fix yourself. Here are a few quick tips to help keep your heating running smoothly this winter:
🔥 1. Frozen Condensate Pipe?
If your boiler suddenly stops working in freezing weather, there’s a good chance your condensate pipe has frozen.
This pipe usually runs outside and can build up ice, causing your boiler to lock out.
👉 How to fix it:
• Pour warm (NOT boiling) water over the outside pipe to gently melt the ice.
• Once thawed, reset your boiler and it should fire back into life.
Tip: A hot water bottle wrapped around the pipe also works really well if you prefer a no-spill option!
🔧 2. Low Boiler Pressure?
Your boiler pressure should normally sit at around 1.0 bar when the system is cold.
If it drops too low, your heating may stop working.
👉 How to top up the pressure:
• Use your filling loop (usually located underneath the boiler).
• Every boiler is slightly different, so for a quick guide, type your boiler make & model into YouTube — you’ll find plenty of clear how-to videos.
🌀 3. Bleeding Radiators
If some rooms are cooler or your radiators are cold at the top, they may need bleeding.
This removes trapped air and helps your system run more efficiently.
(Just remember to check your pressure again afterwards!)
🧼 4. Check Outdoor Vents & Flues
Snow, leaves or debris can block airflow and cause your boiler to shut down.
A quick visual check keeps things running safely.
💡 5. Thermostat Battery Check
If your heating isn’t turning on when programmed, your room thermostat may just need new batteries — one of the most common winter issues.
