Ask a Brooklyn, NY Plumbing Expert: Common Boiler Problems

From Frozen Pipes to Loss of Pressure, Rebmann Can Fix it All

When this customer called Rebmann Plumbing, Heating, and Air Conditioning, they needed service on their boiler because the two cast iron radiators were not heating. When we arrived at the home, we found that the boiler gauge was not working properly and, to repair it, we replaced the boiler feed valve.

Having no heat in your home is just one of the problems you may experience if you have a boiler in your home. Despite their bulky figure, these heating systems are not indestructible and will eventually develop problems over the course of their life. What are these problems exactly?

Common Boiler Problems

  1. Frozen condensate pipe: When the condensation pipes freeze up, it can causes a blockage. This blockage needs to be cleared by a professional.
  2. Pilot light keeps going out: If this is the problem you’re having, you probably have a broken thermocouple. ┬áIn that case, it will need replacing, but fortunately it’s a fairly simple job. Another possible cause is if there’s a damaged air seal.
  3. Kettling: If you live in a hard water area, this is a problem you may experience more frequently, as it’s the build up of limescale on the unit. As the limescale builds up in the boiler’s heat exchange, it causes banging sounds.
  4. Leaking and dripping: There are a number of different things that could cause your boiler to leak, but you would need to find the location of the leak in order to identify the problem.
  5. Thermostat issues: If you’ve never replaced or upgraded your thermostat, it’s possible for that to be the cause of your heating issues. As they get older, they typically become less accurate and misread temperature settings. This results in heat turning on and off by itself. If you don’t want to get a new thermosat just yet, our heating professionals can clean and recalibrate it to get it back working like normal.
  6. No heat or hot water: This can be caused by a variety of different things from broken diaphragms to motorized valve failure. If you have low water levels, that may also be the problem.
  7. Loud banging noises: If there is air in the system, you’ll probably hear a banging, whistling, or gurgling noise coming from your heating system. It may also be caused by the build up of limescale or low water pressure.
  8. Losing pressure: Unfortunately, if you have a loss of pressure in your system, that means you have a leak. Though it does sound like a serious issue, it can usually be remedied by replacing the pressure relief valve and recharging the expansion vessel with air.
  9. Boiler keeps shutting itself off: This could be happening because of low water pressure, thermostat issues, lack of water flow, a pump that’s not working correctly, the failure to circulate the water properly, or air in the system.

No matter what the cause of your boiler problems, though, rest assured that Rebmann Plumbing, Heating, and Air Conditioning can – and will- repair them. Call us today!
