What are the most common boiler problems
The most frequent boiler problems include no heat or hot water, leaks, strange noises, low pressure, pilot light issues, frozen condensate pipes, thermostat malfunctions, radiators not heating properly, kettling, and frequent shut-offs.
The most common boiler problems include:
- No heat or hot water: Often caused by issues with the thermostat, low pressure, or problems with the pilot light.
- Leaking or dripping: Frequently due to a broken pressure valve, worn pump seal, or corrosion.
- Strange noises: Banging, whistling, or gurgling sounds may indicate air in the system, low water pressure, or limescale buildup.
- Pilot light going out: Commonly caused by a faulty thermocouple or issues with the gas supply.
- Low boiler pressure: Can result from leaks, a faulty pressure relief valve, or recently bleeding radiators.
- Frozen condensate pipe: A common issue in winter that prevents proper drainage and may shut down the boiler.
- Thermostat problems: Faulty or outdated thermostats can lead to incorrect temperature readings or inconsistent heating.
- Radiators not heating properly: Often due to trapped air, sludge buildup, or an imbalance in the system.
- Kettling: A problem caused by limescale or sludge buildup, leading to overheating and steam formation.
- Boiler keeps switching off: Common causes include low water pressure, a faulty thermostat, or blockages in the system.
Regular servicing can help identify and resolve these issues before they escalate.
