Water pumps for your central heating systems

Water pumps, also known as central heating pumps, are used to pump water around a central heating system. Put simply, it pumps hot water from the boiler, around the radiators and back to the boiler.

How does a water pump work?

As the water goes around the radiators, it loses heat by heating the room.  The water then becomes cooler and the cool water goes back into the central heating boiler and the process of water circulation starts all over again.

Arco Heating and Plumbing have come to the rescue for many customers and their water pipes.  Below are some water pump problems we have solved in the past:


  • A hot water pump – a water pump should never feel hot to the touch. A temperature above warm, indicates that there is a problem and a water pump replacement is needed.
  • A rattling or humming water pump – there are various water pump noises that can occur and a rattling or humming water pump could mean that the pump is loose.  The mounting or securing will need to be checked for loose screws. Don't delay in getting it fixed as it will only get worse.​
  • A noisy, grating or knocking water pump – is a noise that you do not want to hear. This is a sign that something is wrong inside the pump and that a replacement water pump is needed.

  • Noises coming from a central heating system – is your cue to bleed your radiators as air is trapped inside the water pump.
  • Only some of the radiators get hot – this is a warning that the pump may need replacing.  If only one section of the house is heating up, you could try turning up the pressure.  If this fails, it shows that there’s not enough power to pump water around the central heating system.

This list is not exhaustive and not all water pump remedies are listed here.  One of the Arco team may need to come and assess your problem in person.

Why not give us a call or submit one of the forms with your details and we’ll get right back to you.​
