Knowing When Your Boiler Needs Repair

It is important that during the cold winter months your home is a comfortable temperature. There is something nice about coming home to a warm home during the winter months. However, it seems that winter is when boiler repair is needed. This is simply because the boiler is in use at all times. It is important to know when your boiler is struggling to keep up with the constant need of heat in the home. Here are a few things that you should look for when you are deciding if your boiler is in good condition. 

The Flame

One of the very first things that you should look for is a blue flame. You want the pilot light to be burning blue, but often if the boiler is in bad condition the flame will be a much more yellow or pale yellow color. The problem with this color is that it means the flame is not burning the gas properly. If your flame is not burning the gas properly, then there is carbon monoxide in the home. You should call your technician as soon as you see a yellowish flame. You may also want to consider installing a carbon monoxide detector by the boiler.


The smell of your boiler should tell you a great deal as well. Most gases are not going to have an odor, so if you smell an odor coming from your boiler, you have some serious problems. Often, the boiler will start to smell if it is burning something that it should not. This burning smell is likely coming from wires that are burning, or even some of the insulation. No matter the reason where the smell is coming from, if your boiler is emitting a smell, then you should contact your technician.


Sounds are often one of the first things that will tell you if your boiler is going out. A normal boiler will make sound, but it will often feel like white noise, but if you start hearing a rumbling sound, something is wrong. Often the noise is coming from sediment that heats up and cools down and causes a little bit of expansion. The sediment not only makes a lot of noise, but it can also cut the efficiency of your boiler in half. If your efficiency goes down, that will generally mean your energy bills will go up. Once again, noises coming from your boiler mean you should call your technician.
