Unlimited Claims You can make unlimited claims on your boiler for as long as it has not been declared beyond economical repair BER. You can discuss with them what issue you are having. Be sure NOT to use boiling water, as this can cause more harm than good, and once the contents of the pipe have fully drained and the blockage has been removed, restart your boiler.

A tapping — or gurgling sound like the one described above — could also be caused by a build-up of limescale within the pipes and radiators. If you suspect this is the problem, use a non-acidic cleaner to flush out the system when the heating is turned off. A humming sound coming from your heating could mean that the heating elements in your immersion heater are not functioning properly.

First, check that the thermostat is working correctly. If it is, turn your attention to the central heating pump; this may be set too fast and need slowing down.

Or you might have knocked the valve accidentally and it may have become loose, allowing a constant flow of water into the system. You can reduce the pressure in your boiler by bleeding your radiators, check out this infographic for an easy guide, or by using the pressure relief valve in your boiler.

As water in the system heats up and flows through the pipes, it causes them to expand — and contract again once cooled. Check the position of the pipes and make any necessary adjustments if you find they are too close to the joists or floorboards — you can just use a saw and a chisel to make more room.

If the pipes have room to expand but are still making a noise, pack some light insulation around the pipe as that should help to limit movement and dull the sound. Noisy heating pumps are common in the winter because the heat pump goes into defrost mode.

As the internal valves shift into winter mode, the heat pump can make a swooshing noise which is nothing to worry about. However, a lot of central heating pump problems are the cause of boiler issues. So, if you think there are unusual noises coming from your heating pump, here are a few things you could try:.

A common cause of a noisy central heating pump is the vibration of the boiler unit itself. If you find that this is the case, your heating pump will need securing in place and you could install simple brackets to make it more secure. For a quick fix, try placing something under the boiler like rubber pads to absorb the vibrations and stop the boiler making noise. You could also try turning down the central heating pump speed. It is quick and easy to adjust the pump speed.

Especially if you have a newer model like a Grundfos central heating pump. These pumps usually have 3 speed settings. Simply flick the switch on top of the boiler pump. But just be aware that turning the pump speed down may lead to your radiators taking a long time to heat up.

So if the problem persists, be sure to contact the professionals. Bleed The Central Heating Pump Just like noisy radiators, another central heating pump problem is caused by trapped air locks in the pump.

To remove the air locks you will need to bleed your heating pump. This is a similar job to bleeding a radiator. You should find the pump bleed screw on the side of the heating pump. Turn the pump heat screw about half way and slowly let the air out. Be prepared for a bit of water leakage and keep a tea towel at hand.

To check if this is the case, make sure your boiler pump is switched off and check the fan blades. You may find that there is a loose component tapping the blades causing the heat pump to make noise.

If you're thinking of purchasing a radiator from Just Radiators, you now know exactly what to do if you happen to hear any noises in your heating system.

Just Radiators. My Account. November Why is my radiator making a noise, and how do I fix it? Introduction: No matter what kind of radiator you have, you generally expect it to operate reasonably quietly - whether you have designer radiators or more traditional vertical and horizontal radiators, you expect silent operation. There are, however, occasional noises that radiators can make, which can lead you to start worrying. With boiler repairs and plumbing work always seeming to be such an expensive prospect, you want the peace of mind that comes with knowing that your radiator's noises are actually quite normal.

This applies to all types of radiators - chrome radiators, RAL colour radiators, electric radiators, and more. Knowing the noises While radiators are usually quiet, they're not designed to be totally silent all the time - there are the occasional creaks and groans that you come to expect.

These will often occur as the system is heating up, or when it's cooling down again - the metal will contract and expand naturally, and will sometimes creak. If you hear unusual noises, however, there are a few common symptoms. Here are the three most common reasons for noisy radiators. Air bubbles Your central heating system is a vast network of piping, which means that there are going to be odd occasions where air bubbles form.

This is quite normal, indeed your system has been designed to allow for this, as it's a natural symptom of the water flushing through the system water itself carries small air bubbles, which get trapped. Clicking noises are reasonably common to hear when you have an issue with air bubbles, as the warm water flowing through the pipe will leave air bubbles behind it. These bubbles expand and collapse in your piping.

Air bubbles are a common issue, and not expensive to deal with, but they can lead to larger problems if you just leave them - so it pays to get the issue remedied as soon as possible, in order to prevent more complex issues. Warping pipes Another common cause of noisy radiators is pipe warping.
