1. The boiler isn’t radiating heat
If your boiler isn’t heating your home, there may be an issue with the thermostat. Try replacing the batteries to get the system back up and running. If that doesn’t solve the problem, there could be a faulty motorized valve or broken system diaphragm. These complex components will need to be replaced by a professional.
2. The boiler’s leaking
If your boiler’s leaking, there’s likely an issue with one of the internal components. A leak from the pressure relief valve signals that the boiler pressure may be too high. If the leak is around the pump, a seal may have worn out and need to be replaced. Corroded pipes can also cause leaking. It’s best to have an expert come and determine the source of the leak.
3. The boiler’s making bubbling noises
Do you hear loud bubbling noises coming from your boiler? This phenomenon is called kettling and is usually the result of excessive limescale or sludge accumulating on the unit’s heat exchanger. Kettling makes your boiler work overtime, which can cause it to wear out prematurely. We can flush out your system to ensure your boiler continues to run smoothly.
4. The boiler has low pressure
Ideally, your boiler pressure should be 1.5 or 12 PSI. Otherwise, it won’t work correctly. Several issues such as a system leak, recently bled radiators, or a faulty pressure relief valve can cause low boiler pressure. Rather than waste your time trying to get to the root of the problem on your own, call a professional to diagnose and fix the issue promptly.
5. The boiler’s pilot light doesn’t stay lit
If the pilot light on your boiler won’t stay on, you may have a problem with your thermocouple. Alternatively, the gas nozzle could be covered in carbon. First, call your gas supplier to determine if they’re experiencing any service interruptions. If that’s not the issue, call a professional. Gas is a highly flammable substance that must be handled with care.
