Common Warning Signs Your Boiler Needs Professional Attention
Catching a struggling boiler early saves you emergency fees, frozen pipes, and cold nights. Watch for these warning signs — and if your boiler is past 15 years old, it may be worth weighing repair costs against a new high-efficiency installation:
Cold Spots on Radiators
Radiators cold at the top usually need bleeding; cold at the bottom can mean sludge buildup restricting circulation
Kettling — Rumbling Like a Kettle
Banging or rumbling from the boiler means scale on the heat exchanger is trapping steam — and straining the whole system
Leaks & Drips
Water around the boiler, a weeping relief valve, or wet pipe joints call for attention before corrosion spreads
Pressure Keeps Dropping
If you’re topping up the system every week, a leak or a failing expansion tank is hiding somewhere
Pilot Won’t Stay Lit
A pilot that keeps going out often means a failing thermocouple or a draft problem — a quick, inexpensive fix when caught early
Gas Bills Creeping Up
A boiler losing efficiency to scale and short cycling draws more gas to deliver the same heat
