Central Heating Pumps


Central heating pumps are designed for commercial and industrial purposes and are important fixtures to help pump water to heating systems. The boiler sends water around the building directly to the radiators or taps. This process ensures a consistent and even distribution of heat throughout your home. A central heating pump can be used for potable water, hot water, underfloor heating, and HVAC systems.

Efficiency of Central Heating Pumps

Investing in a high-efficiency central heating pump can substantially affect your energy bills in the long run, reducing both money spent and energy used.

Factors Affecting Efficiency:

1. Pump Size: Choosing the right pump size for your heating system is crucial for optimal performance.
2. Temperature Control: Implementing temperature control strategies can enhance efficiency.
3. Regular Maintenance: Keeping your pump well-maintained is key to ensuring it operates efficiently.

We offer customers Preventative Maintenance Contracts that will help optimise the performance of your pump and equipment and extend their operational lifespan.

Range of Central Heating Pumps

Grundfos Central Heating Pumps

Central heating pumps are important for creating a comfortable setting in a commercial building such as office premises or residential buildings. Grundfos manufactures central heating pumps that are highly efficient and offer total reliability and easy installation. It allows you to save big on energy with its intelligent technology.

The Grundfos Magna Pump range is an ideal solution for heating applications in commercial buildings. The ALPHA range is designed for heating applications, and with its AUTOADAPT technology, it can support the system’s demands and ensure optimal comfort throughout the building whilst being energy efficient.

Wilo Central Heating Pumps

The Wilo-Yonos PICO-D is a twin-head central heating pump designed for hot water heating systems and industrial circulation systems. This new generation of highly efficient pumps, together with the new functions, gives maximum convenience for commissioning and maintenance. The Wilo-Yonos uses pictograms in its default settings for radiators and underfloor heating, saving time during commissioning.

Wilo central heating pumps are continuously improving in power consumption and energy saving. The compact design of the new models means pump replacement has become easier.

How to change a central heating pump

Step 1: Switch off electrical connections 

The electricity supply to the central heating system must be switched off, ensuring the power will not accidentally come back on when the pump is replaced. Alert everyone inside the building before this is done.

Step 2: Find the central heating pump 

The central heating pump might not always be in plain sight; check under the stairs or in the airing cupboard.

Step 3: Take a photo of the electrical wiring 

Taking a picture of the wires helps when connecting the new central heating pump. Labelling the wires for ease of reference is a simple and effective way to help when connecting the new pump.

Step 4: Shut off the isolating valves 

The isolating valves are found on the body of the central heating pump and must be closed off. Closing the isolating valves will stop the water supply to the pump body. If no valves are used, the heating system must be fully drained.

Step 5: Waterproof the area 

Spillages and leaking can occur when the central heating pump is replaced; therefore, towels or large bowls must be placed under the pump to capture any water.

Step 6: Loosen the union nut 

The union nuts hold the central heating pump in place. To remove the nut, turn it anti-clockwise and then remove the pump to be replaced.

Step 7: Replace the pump 

The new pump and union nuts must fitted securely. Washers should not be reused because they tend to contract over time. Check for potential leaks by opening up the isolation valves.

Step 8: Dry the pump 

No wiring should be reconnected until the unit is completely dry and all valves and the pump are fitted securely.

Step 9: Testing your new pump 

Switch the electricity supply back on and start the central heating system. While the heating system is running, inspect the pump and connections for leaks and report any unusual noises to a plumber.

Step 10: Bleed the pump and complete the installation

Any trapped air has to be bled out of the system. The bleed screw on the pump can be turned anti-clockwise until a hissing sound is heard. Bleeding the radiators is a good practice because it balances the entire system.

Maintaining a Central Heating Pump

  • Routine Inspection

Regularly inspect your pump for any signs of wear and tear. Check for leaks, strange noises, or vibrations, which can indicate potential issues.

  • Lubrication

Proper lubrication ensures smooth operation. Consult your manufacturer’s guidelines for lubrication intervals and methods.

  • Bleeding Radiators

Bleeding your radiators releases trapped air, allowing your central heating pump to work more effectively.

Troubleshooting Common Issues

Even with proper maintenance, issues may arise. Here are some common problems and how to address them.

  • Noisy Pump

If your pump makes unusual noises, it could be due to air in the system or worn-out bearings. Try bleeding radiators first, and if the noise persists, consider our professional assistance.

  • Reduced Heat Output

A decrease in heat output can indicate blockages in the pump or pipes. Inspect and clear any obstructions; if the problem persists, contact a technician.
