Common causes of boiler issues

by admin on November 1, 2013

A boiler is a strong contender when it comes to ways to heat your home in the winter. Their popularity dates all the way back to the time when they were invented – around the early 1900s. Boilers are efficient and streamlined, and they make sense. A boiler heats water and then sends that heated water via a series of tubes to radiators, which “radiate” the heat outwards and through the room, and eventually throughout your home. A boiler creates a comforting kind of warmth – a warmth that is not too moist or dry. However, just like any other type of system, boilers have their unique problems and issues, but nothing that can’t be remedied relatively quickly. Here are some common causes of boiler issues.

One of the most common causes of boiler issues is that air has entered the system. If you can hear strange gurgling sounds, banging, whizzing or whistling coming from your boiler or any of the pipes, there is a good chance that air has gotten through. Air can go through a boiler system pretty easily and is often contributed to low water pressure. So, make sure to increase the water pressure and you may notice that the strange sounds will go away.

Another big problem is when the pilot light goes out. If you have the gas on, this could be a big problem. If you don’t have a detector and you have an older unit, the pilot going out could be a really big problem. In most cases, the pilot light will go out because you need a new thermocouple. Replacing the thermocouple should be relatively easy, but if you don’t know what you are doing, you may want to call a professional boiler repair company, like Gas Plumbing Heating –

Next, you may have a leaky boiler, which could pose a really big problem. A leaky boiler could cause water damage, mold to build up around the unit and other issues. Not only that, but a leaky boiler could cause the whole unit to lose pressure, which means that you could be left without heat. In order to fix a leak, you need to first find out where it is. Oftentimes, a leak is usually coming from in or around one of the pipes that spreads water throughout the unit. Before fixing the leak, make sure to shut off the water, because the last thing you want is for scalding hot water to spray all over the place and on you.

Lastly, limescale is another big problem when it comes to boiler issues. Limescale builds up over time and is basically a mineral deposit that starts to form on the sides of the boiler unit. Limescale, overtime, can start to erode metal and plastics, which could cause a serious issue down the line. In order to remedy this, it is critical to switch out the water in your boiler unit from time to time. Also, you don’t want the water levels to get too low. The more air you allow in your boiler, the more of a chance limescale has to build up and it can be very hard to remove once it does.
