Central heating pump
What central heating pump does is, it circulates the hot water around the radiators. You may seem the pump in its smallest size but it has a significant role in heating your home. This is the pump which helps in pumping hot water back to the boiler which results in warming up your room that you enjoy.
Where the pump is located?
You can find the central heating pump close to the boiler itself. The reason for such location is that the pump can start circulating the water as soon as the boiler is done with the heating. It helps in warming up your entire room rather than clamping up some warm air in your cupboards.
What could be the possible reason for the noise?
If your boiler is making noises, it could mean that the limescale has built up. The kettling noise comes from the hard-water that has built up inside the boiler’s heat exchanger. You can remove the limescale that has been build up in the heat exchanger. You can use chemical descalers which will help in pumping out the excess limescale.
After that, you need to flush the system several times. Prefer using clean water. In order to avoid any corrosion, add some inhibitors to the system. Another reason for the noisy boiler is due to the low water flow. Modern boilers come up with specific flow rate that makes sure it sticks to your requirements

Often times, the vibrating units can create huge problems in the pump movement. You need to secure the vibrating unit in order to reduce the painful noises. You can install the brackets for that extra security. Sometimes, the excessive speed of the pump results in the high noises. You can turn it down and check if it solves the problem. If you experience that the water is heating up too slowly because of the pump speed, just call an experienced engineer
The best way to cure the central heating troubles is to identify the problems beforehand. For example:
The airlock issue
When the air gets trapped in the pump unit, it causes the blockage which obstructs the smooth flow of water. That’s why you get to hear that humming noise coming from it.

All you have to do is to simply turn on the bleed screw and it will automatically release the excess air trapped inside.

The kettling noise comes from the hard-water that has built up inside the boiler’s heat exchanger. This will affect the central heating pump as well which will also carry up the formation of such blockage. You can remove the limescale that has been build up in the heat exchanger. You can use chemical descalers which will help in pumping out the excess limescale.
After that, you need to flush the system several times. Prefer using clean water. In order to avoid any corrosion, add some inhibitors to the system.
Uneven speed settings
The modern heating system has all been equipped with the speed settings that don’t require any manual work. It can adjust the flow rate but many times you may experience issues like in 3 settings, the lowest will set the flow too slow while the highest will set it too fast. Whatever is the setting, make sure it goes with your central heating system.
