Common Problems and Issues with Boilers and Radiators

Our plumbing experts specialize in repairing gas, oil, electric, and steam boilers as well as all types of radiators, including hydronic radiant floor heating systems. Contact Akian Plumbing, Heating & Air Conditioning if you notice any of these common issues:

• Faulty Thermostat: If your boiler is not responding to the thermostat, the thermostat may have low batteries or not be programmed to run at a specific time. It could be your boiler’s control system has failed. But there are many easily fixable issues that can cause a thermostat not to work. Check whether it’s too far from the boiler or if something is interfering with it. If you can’t find a solution in the instruction manual, contact the manufacturer or a repair professional.
• The Pilot Light Goes Out: If the pilot light in your old boiler keeps switching off, a faulty thermocouple may be to blame. It can cut off the gas supply. Other potential causes include drafts or material build-up; if you’re not comfortable reigniting the pilot light yourself, or it is any color other than blue, call an experienced technician. If the pilot light is yellow or orange, the boiler will not only be inefficient, but may also release carbon monoxide.
• The Boiler Is Not Turning On: When the boiler doesn’t turn on at all, there may be a power supply issue. Check if other appliances are off too. Also check the circuit breaker for any tripped switches. If the boiler goes on but keeps turning off, have someone check for a blockage, low pressure, or other issue.
• No Hot Water: The boiler’s purpose is to provide hot water and heating. There can be many things wrong if you’re not getting hot water. The issue may be with the thermostat, a valve, diaphragm, or other component, while low system pressure may prevent the flow of heated water. Many of these issues require professional repairs.
• Low Boiler Pressure: A built-in pressure gauge will tell you the boiler’s pressure, which should be set to around 1.5 bar. The appliance won’t operate normally if it is below 1. Low pressure can be caused by a leak, failed seal, or a problem with any number of components. Since there are so many possibilities, don’t attempt to disassemble the boiler yourself; it’s highly recommended to contact an engineer who specializes in boiler repair.
• The Boiler Is Leaking: A leak usually means an internal component has failed. An underlying issue, such as a worn seal or high system pressure, may be to blame. Pipe corrosion can also lead to leaks. A technician can help determine the source of the problem and fix it or determine whether an installation issue is causing trouble.
• Frozen Condensate Pipe: It’s not uncommon for the condensate pipe to freeze in cold weather, as it transports condensate from the boiler to a drain located outside. Frozen liquid can cause a blockage. If the condensate backs up into the boiler, the unit can break down. A pipe installed in an unheated garage or that’s fitted externally is more prone to freezing.
• Strange Noises: If your boiler starts making banging, gurgling, or whistling noises, contact a repair technician. Boilers sometimes make noise when operating normally but unusual sounds can mean there is air in the system, a build-up of limescale, or low water pressure. The boiler may also be overheating, so it’s critical to get it looked at right away.
• Radiator Faults: Radiator damage or a build-up of sludge or air inside radiator tubes can disrupt the flow of heat. This can lead to uneven heating from room to room. Not fixing the problem can lead to further damage. Sometimes, it can be resolved by bleeding the radiator. Call a technician if you don’t know how to do this, or to decide if you need radiator repair.
