Diagnosing Problems with an Electric Boiler by the Sounds It Makes

Construction & Contractors Blog

Boiler systems in residential settings are just as convenient as they are in commercial settings because they provide the dual function of heated water and home heating in one appliance. The majority of modern residential boilers are electric powered, which gives homeowners an even bigger advantage when it comes to efficiency. However functional and efficient electric boilers can be, they do tend to make a little more racket than the average home heating system, especially when there is something wrong. Here are a few of the most common noises you may hear coming from your electric-powered boiler system and what these noises could indicate. 

Loud Hissing or High-Pitched Squealing

Occasionally, a boiler will release pressure from within the tank and you will most definitely hear this happen. However, the sound of hissing or high-pitched squealing like a ready tea kettle on the stove is not a noise that you should frequently experience from your home's boiler unit. This kind of sound means that there is too much pressure building up inside of the water holding tank. This is often caused by a leak in the water delivery lines, which allows air flow in along with the water that is provided.

To address the problem, open the pressure release valve fully first, and then check the water delivery lines for signs of damage or leaks. If you do find something wrong, fixing the problem will be as simple as ordering a replacement line and having it installed or grabbing a good set of pliers and making the repair on your own. However, you should keep in mind that in order to achieve this repair task, the water tank will have to be fully drained and the pressure regulator will have to be reset. Therefore, a lot of homeowners would rather leave this task to a professional.  

Consistent Gurgling and Noises from Inside of the Tank 

It is quite common to hear some bubbling anytime you are dealing with a large holding tank that holds pressurized water. But, if you hear the noises regularly, it may mean that you have a problem. There are filters inside of the tank that are designed to capture air bubbles and eliminate them in the heating process and the gurgling and bubbling sounds should not be present all the time.

Occasionally, these filters get blocked by minerals and deposits and water continues to aerate as it moves inside of the tank, which can cause problems with even heat distribution eventually. To rectify the noisy problem, you should have a professional take a look at your tank to see if the filters are indeed clogged or in disrepair.  

The bottom line is, your boiler should not be making excessive noise when it is in operation and if it is, there is usually something wrong.

Stop Mold in Its Tracks

Hi, I'm Carey Johnson. Mold can be more dangerous than you might realize. I learned that when my little girl started having asthma and allergy attacks inside the house. I couldn’t figure out what was causing it. We changed the filter in the air conditioner frequently, and we kept the house very clean. We couldn’t, however, figure out where the allergens were coming from. Finally, we discovered the mold that was growing on the floor of the attic – right above my daughter’s room! No wonder she was having breathing problems! Once we found it, we went right to work learning how to get rid of it for good. We ended up reconstructing the attic, and I learned that I enjoyed learning about construction.
