Common boiler problems for homes and commercial locations:

At All Week LLC we appreciate home owners and clients who are curious about heating system technologies and ways to enhance their systems for a better quality home comfort. And so we are sharing this short list of most common boiler problems faced by both residential and commercial. Please remember that at we are available in Northern NJ to help resolve any of these problems, whenever needed.

• No heat or hot water – potential causes include broken diaphragms and airlocks, failure of motorized valves, issues with the thermostat or low water levels.
• Leaking and dripping – a variety of issues could cause your boiler to leak water. It will depend on where the water is leaking from to determine the cause.
• Strange banging, whistling or gurgling noises – air in the system is a common cause, alternatively it could be that the water pressure is too low or it’s kettling. Pump failure, particularly in older systems, could also be responsible for strange banging noises.
• Pilot light goes out – could be a broken thermocouple which is removing the gas supply to the pilot light, a draught blowing the pilot light out or a deposit built up in the pilot light.
• Losing pressure – a water leak in the system is the most common reason for a loss of pressure. But it could also mean that the pressure relief valve needs replacing.
• Frozen condensate pipe – Thawing a frozen condensate pipe should ideally be done by a qualified engineer.
• Thermostat issues – if the thermostat is losing accuracy or turning the heating on/off when its not supposed to it might be time to invest in a newer, more energy efficient one.
• Kettling – hearing a strange rumbling noise? When lime scale builds up on your boiler’s heat exchange you get kettling.
• Radiators not getting hot – corroded pipework can cause sludge to gather in the system, preventing the free flow of hot water to the radiators. Chemically cleaning or flushing the system will remove these deposits.
• Boiler keeps switching itself off – could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly.
