A boiler plays a crucial role in warming your home and providing you with hot water, especially during the cold months. It essentially works by heating water, which is then pumped around your home. While the steam gets released into your space, the hot water is also supplied whenever needed.

The problem is that when your boiler remains inactive for so long, it is suddenly forced back to life during the winter. Without regular inspection and upkeep, however, the chances are that some potential problems will arise. That said, here are five common issues associated with your boiler and what you can do to address them:

1) Cold Water

Your boiler is supposed to provide you with hot water, and not the opposite. But nothing can be more frustrating than getting cold water just when you need it the most. Your unit may have some issues like inappropriate thermostat setting or low water levels. In such cases, be sure to check both possible issues and do the needful—adjust the setting or pour in enough water. However, if the problem has to do with the diaphragm or valve, you will need to replace them with a new one.

2) Strange Sounds

One thing you should be wary of is when you start to notice some strange sounds in your boiler, especially when you begin hearing rumbling noises like a boiling kettle. When encountered with these issues, it may have a limescale buildup or a muck in the heat exchanger. This buildup can eventually obstruct the water flow, causing overheating and the boiling water to hiss. As this problem is harmful to your unit, it’s best to contact a gas safe registered engineer to flush out the unwanted deposits before the problem escalates.

3) Boiler Leaks

There is nothing more alarming than experiencing a boiler leak. This leakage may have to do with a handful of reasons, such as a damaged internal component (pump seal or pressure valve), high-pressure level, and corrosion on the pipes or tank itself. Be sure to have the broken parts replaced, adjust the pressure level, and fix the rusted pipes or tanks. Ultimately, getting professional services to address these will make a huge difference!

4) Frozen Condensate Pipe

Keep in mind that a boiler consists of a condensate pipe. Typically made of plastic pipe, it serves to transfer acidic water away from the unit. Due to its location, however, it has the tendency to get frozen during the winter, which is why your unit will display a warning sign or fault code. For this reason, be sure to melt it with a warm bottle or pour it with hot water to warm up the pipes.

5) Low Pressure

At times, the needle of the pressure gauge may go below one. When this occurs, it means that there’s a low-pressure level, and this is also indicative of your heating system not working properly. The problem may have to do with a system leak, broken pressure release valve, or recently bled radiators. In such situations, be sure to have them checked and fixed by an expert so that these problems won’t surface again!


At this point, we’ve covered five common issues with a boiler—cold water, strange sounds, boiler leaks, frozen condensate pipe, and low pressure. That said, be wary of all these and follow the practical steps discussed above in addressing these problems.

Ultimately, it’s best to hire professional services for your boiler checkup and upkeep just before the cold months so that you can remain comfortable indoors. Also, regular boiler inspection and maintenance will make a difference in keeping your unit in top shape and working condition!
