Boilers are an expensive investment and it can be difficult to handle a sudden repair or replacement if you are given no warning beforehand. Fortunately, there are many ways in which you can simplify the process of repairing or replacing a boiler. You must first know some of the many problems a boiler can have that are most common, such as not producing enough hot water.

No Heat or Hot Water

There are a few reasons for this problem but the most common potential causes include broken airlocks and diaphragms, failure of motorised valves, low water levels, and issues with the thermostat. A great place to start is to check whether your boiler is not working because of the pressure or the thermostat. If you believe that you have a broken diaphragm, airlock, or valve, it may be that you need to have the part replaced by a professional before you will see your hot water returned.

Not only will you likely save money but depending on the problem, it could save your life.

Leaking or Dripping

A wide variety of underlying issues could cause your boiler to lose water over time and you can often determine the likely cause by searching for the source of the water leak. However, you should never try to fix a leaking gas boiler on your own as this can be exceptionally dangerous to your health and a professional should always be brought in for the work. The most common cause of leaking water is a broken internal component such as a pressure valve or a pump seal, which is a relatively easy fix.


Just as you would immediately notice a new and odd sound coming from your car’s engine, it is likely that you will notice fairly quickly if you hear any banging, whistling, or gurgling noises emanating from your boiler. Air in the system is the most common cause, although it could be that the water pressure is too low or that it is kettling. Imminent pump failure, especially if you own a very old boiler, could be the problem causing the strange banging noises.

The type of noise might help you determine exactly what type of problem you might have inside the boiler. For example, a noise similar to that of a kettle boiling is typically the result of kettling and there are many other particular problems that will cause unique sounds. A professional will likely know how to find the source of the problem, diagnose the issue, and then help you determine if you need a repair or a full replacement to fix the problem for the long term.
