4 Great Tips For Quieting A Noisy Boiler


If you've been hearing pops, crackles or knocking noises from your basement area, then chances are it's due to your boiler making a loud racket. It's not out of the ordinary for a boiler to get a bit noisy, but that doesn't mean you have to live with the noise. Here are a few tips that can help you quiet your boiler and bring a bit of peace and tranquility back to your home.

Try Turning Down the Heat

Most boilers are set to operate around 160 to 180 degrees Fahrenheit. Any higher and it's likely that you'll bring your water to a boil, which could cause it to make noise. Make sure your thermostat is set to the correct temperature. If the thermostat is already set properly but you still have temperature issues, you may want to have the thermostat itself checked out by a boiler repair service.

Bleed Off Excess Air

When air finds its way into the boiler through a defective valve, a bad bleed screw or a pressure leak, it can create banging and clanging noises as air pockets travel through the water pipes. To fix this problem, you'll need to bleed this trapped air from the boiler:

  • Shut off the heat and allow the water to cool down to a safe temperature. Afterwards, locate the bleed screw on the radiator at the highest point of your home.
  • Cover the base of the bleed screw with a towel and place a bowl underneath to catch water runoff. Slowly open the bleed screw by a quarter to a half-turn and wait for water to trickle out of the bleed valve.
  • Close the valve and repeat the process for each room at the highest points of your home, then work your way downwards.
  • Locate the bleed button at the boiler's expansion tank. Press and hold the button until you see water trickle out of the valve.
  • Make sure all valves are fully closed and turn the heat back on.

Isolate Those Pipes

Popping and rubbing noises could also be caused by the pipes coming into contact with wooden structures. As hot water flows through the heating pipes, it can cause the pipes to expand along their length and make contact with the surrounding wood.

Plumbing and heating expert Richard Trethewey recommends isolating the affected pipes with plastic noise-insulating clips. Simply slip the clip around the pipe and affix the clip to a nearby mounting point. This should keep the pipes from making any more noise due to expansion.

Consider Descaling Your Boiler

Calcium and lime scale deposits can create localized hot spots in the boiler, leading to kettling as air pockets form and collapse around the superheated areas. Fortunately, there are specially prepared chemicals you can use to remove and flush these deposits from your boiler, many of which are relatively easy for do-it-yourselfers to use. Of course, you can also have a professional clean and inspect your boiler on your behalf for greater peace of mind.
