Why is my radiator making noise?
Here are some of the most common ones and what you can do about them so you can achieve some glorious silence.

Why is my central heating making a loud noise?
Anything else is likely to have an adverse effect – and that often manifests as banging, clanking or gurgling noises. Air in the system is the result of oxygen bubbles and other gases forming inside your central heating system. The air takes up space in the radiator which should be occupied by hot water.
Why is my radiator banging and clanking?
Banging and Clanking Radiators: Does your radiator sound like a mentally unstable auto mechanic repeatedly hitting various parts of a car? This is most likely steam trapped in the pipes. As steam goes through the system, it pushes water forward incredibly fast. When that water comes across an obstacle, you hear it.
How do I stop my radiator from humming?
Air vents, however, are most effective for radiators on higher or top floors. To get rid of trapped air elsewhere in the system, put an air separator in the piping, as close to the boiler as possible. Together, opened air vents and air separators will get rid of excess air throughout your system.
Why is my radiator making a weird noise?
This is because when the heating comes on and hot water is pumped around your central heating system, it makes contact with the cold metal of your radiator and the metal begins to warm up and expand. It's the expanding metal that's making the clicking or creaking noise.

1. Normal Noises
Your radiator might make a quiet hissing noise as the room gets close to the desired temperature. The radiator will start to restrict water flow, and you’ll hear a quiet hiss.
2. Banging Sounds
Banging sounds are almost always caused by your pipes. Either they haven’t been adequately secured to begin with, or over time they have come loose. If your pipes run outside your walls, then you can easily check them for any movement. If they have been hidden behind the walls, you’ll need to listen to determine where the sound is coming from.
3. Running Water Sounds
If you hear a sound like running water using your radiators, it indicates that limescale and/or sludge have built up inside your central heating system. Sludge is caused by corrosion and is made up of various metal oxides. It creates a barrier that stops the water from flowing through the radiators properly.
4. Gurgling Sounds
Gurgling sounds are caused by air in the central heating. Air is one of the most common causes of unwanted noise from your radiators. Air in the system is caused by gases and oxygen bubbles building up inside your central heating.
5. High-Pitched Whistle
A whistle means there is a tiny hole somewhere, or you have not fully closed the valve after bleeding it. Check the radiators bleed valves are all tightly closed. If it persists, you might need a plumber to locate it for you.
6. Humming Sounds
If the pump in your boiler isn’t configured properly, it may run too fast or high. That will cause the water to flow too rapidly and can cause a humming sound when your central heating is switched on. In older systems, you might be able to fix it yourself as the pump will be accessible in your airing cupboard.
7. Combined Hissing and Rushing Noises
If you can hear hissing or rushing noises in your radiators when they’re on, your system might not be properly balanced. Another symptom of this is if your radiators located furthest from the boiler aren’t as hot as those that are nearer. That will result in some rooms being too warm while others are still too cold.
Why is my radiator making a whistling noise?
If your radiator is making whistling noises it’s likely to be one of three things. Either your water flow rate is too high, there is a limescale build-up in your radiators, or the drain valve is open.

Why is my radiator making a clicking noise?
Clicking or ticking noises from your radiator is normal, as it’s the sound of the radiator metal expanding or contracting during the heating and cooling process. Is the noise coming from underneath floorboards? If so this is the sound of your pipes expanding which is also normal, and nothing to be concerned about.
Why is my radiator making a bubbling or crackling noise?
Crackling, fizzing, banging, or bubbling noises from your radiator indicates that the likely cause is air trapped in the system. To fix this, take the radiator key and bleed all the radiators, even those that aren’t making a noise. This will ensure that you have removed all the air.

This is what causes a clicking or gurgling noise within your boiler.

How Loud is it? If you can't hear it when your right next to it I wouldn't worry my h110 makes a noise but I can't hear it unless I put ear beside the pump.

Also, the pump should get the full 12v. No fan profiles. Fluctuating the pump is not recommended. Similar to closing the throttle body while in boost. The charge hits the butterfly and causes the turbo to chatter from back pressure. The reason for bypass/blow-off valves. Steady flow is the best way to go. Haha a poet..

The orientation of the rad is usually the issue. Should be treated as if it's gravity fed. Any orientation other than hoses at the bottom causes ticking sounds. Hoses on the sides shouldn't be a problem but I've heard it tick that way as well.

Right. If the sound is from the rad, it's a little air. It'll fix itself over time, but try to lean the case over so the hoses are at the bottom and I guarantee it'll go away.

On its side now, sound still there, but I didn't expect for it to go away immediatly.

Have you confirmed it's not vibrations? I once didn't have a screw completely tight and it caused a washer to rattle a bit. If it's a tick, it's air. If it's buzzing... vibrations. If the sound is definitely from the rad.
