Boiler Repair FAQs
What causes a boiler to leak?
A leaking boiler is a serious issue that requires immediate attention to prevent water damage.
Common causes include:
- Pressure relief valve failure: Excess pressure forces water out of the valve.
- Corrosion: Internal pipes or the tank may deteriorate over time.
- Worn seals: Pump or internal seals can degrade and begin to leak.
What to do: Turn off the boiler immediately and contact our team.
Why is my boiler making banging noises (kettling)?
Banging or rumbling noises usually indicate kettling. This occurs when limescale or sludge builds up on the heat exchanger, restricting water flow and causing overheating and steam formation. A professional power flush or descaling treatment is typically required to resolve the issue.
Why does my pilot light keep going out?
A pilot light that will not stay lit is often caused by a faulty thermocouple, a blocked pilot tube, or drafts that blow out the flame. Our technicians can safely identify and repair the underlying issue.
Can regular boiler maintenance prevent boiler repair?
Yes. Routine maintenance is the most effective way to prevent breakdowns and costly repairs. Regular servicing improves efficiency, lowers energy bills, and extends the lifespan of your boiler.
During a professional service, a technician will:
- Check system pressure
- Clean the burner and inspect the heat exchanger
- Test safety controls and thermostat operation
- Clear condensate lines and bleed radiators
Preventive maintenance today helps avoid emergency repairs later.
What is the life expectancy of a boiler?
Most boilers last between 15 and 25 years, depending on the model, usage, and how well the system is maintained.
Is it worth repairing a boiler?
Repairs are usually worthwhile if the boiler is under 15 years old and the issue is minor or cost-effective. If the unit is older or requires frequent repairs, replacement is often the better long-term investment.
What’s the most expensive part of a boiler?
The heat exchanger is typically the most expensive component due to its complexity and critical role in heating efficiency.
