A noise that sounds like a drone, an aeroplane or even a foghorn (as demonstrated in this example) is characteristic of a pump that’s on its way out. There’s a variety of causes for this, such as a simple mechanical pump failure or air and debris caught in the boiler’s impeller.
Is it common for boilers to explode?
Boilers can certainly explode. This is usually due to a build-up of pressure or mechanical failure due to the boiler deteriorating. Technology has significantly decreased the frequency of boiler explosions, making them a safer way to heat your home.
How do I stop my boiler from making noise?
Ways To Reduce Boiler Noise
- Add central heating inhibitor, a scale reducer (in hard water areas) and a boiler filter.
- Have a heating engineer do a hot-flush, or power flush on your heating system.
- Check the boiler for leaks, operating pressure and water flow rate.
- Remove airlocks in the boiler’s heating pump.
Why does my boiler make noise at night?
The cause of these sounds comes from air infiltrating the system. It impedes the flow of the water, which leads to pressure issues and thus uneven heating. Sometimes frozen or leaky pipes can lead to this infiltration of air, and sometimes it’s related to faulty valves.
What causes boilers to explode?
There are many causes for boiler explosions such as poor water treatment causing scaling and over heating of the plates, low water level, a stuck safety valve, or even a furnace explosion that in turn, if severe enough, can cause a boiler explosion.
Can a leaking boiler explode?
Water heater explosions are terrifying, and they can happen. Anything that causes excess pressure on your water heating system, such as a poor anode rod, or a lot of sediment buildup, can all cause your water heater to explode. A gas leak can also cause your water heater to explode because it is a tremendous fire risk.
Is it OK to turn boiler off at night?
Some boiler systems may be more temperamental than others, so switching it off for a longer time than usual could trigger an issue with your central heating. Having your boiler switched off for a prolonged period of time could also cause elements such as your valves and pump to seize up.

What to do if your boiler is not working?
Open bath valves or turn your internal filling key to allow cold water into the system, this will repressurise the system. When the gauge reaches 1.5 bar close both valves. Remove the filling loop if it isn’t a permanent attachment. Turn the boiler back on.
Why does my boiler gurgle when I Turn on the water?
If the water pressure is too low, this may be the culprit of your gurgling noises. Your boiler will have a pressure gauge, also known as a manometer, located in the area where the pipes are connected to the boiler itself.
Why does my central heating make a tapping noise?
Another cause of a tapping noise in your system could be bits of central heating sludge (a mixture of metallic elements and rust from the metalwork in your system) that have broken off and are brushing against the sides of pipes and radiators as they get pumped around your system.
