Common Boiler Problems

Here are some regular problems you might have with hot water and steam boilers. While you may be able to handle a few of these issues without extra help, you may need a specialist from D & K Heating Service Experts for more difficult heat repair.

  • Thermostat isn’t accurate. Make sure that it’s switched to “on” and the proper settings. Otherwise, your thermostat may need to be replaced.
  • No heat. Worn-out parts, thermostat problems or low water levels could be at fault.
  • Leaking or dripping. Can be caused by a broken internal part, worn-out seal or deterioration.
  • Banging, whistling or gurgling sounds. Air in the system, low water pressure or impending part failure can create these noises.
  • Rumbling or kettling noise. Limited water flow caused by lime and sludge buildup in the heat exchanger. This causes water to overheat and boil.
  • Pilot light is out. Caused by a failing thermocouple, draft or built-up deposit. Natural gas could also be switched off.
  • Pressure is too low. Water could be leaking, or a pressure valve may need to be replaced. Can also be caused by radiators that have been bled recently.
  • Condensate pipe is frozen. This pipe runs outside, so there is a danger of freezing. Melt it by pouring warm water over it.
  • Radiators aren’t getting hot. Caused by sludge or air buildup in the system.
  • Boiler keeps turning itself off. Could be caused by several issues: low water pressure, thermostat issue, closed valve causing low water flow, air or pump not circulating water properly.

Not scheduling regular service can often cause boiler breakdowns. D & K Heating Service Experts can recommend a plan that could help you avoid costly fixes—and may increase your equipment’s efficiency.
