Heating Pump Replacement

What heating pump replacement covers

A heating pump replacement focuses on getting reliable circulation back into your central heating system, with checks to confirm the pump is the cause of the fault.

• Fault diagnosis to separate pump issues from controls, valves, wiring or airlocks
• Safe isolation and removal of the existing pump
• Supply and fitting of a like-for-like or correctly specified replacement
• Refilling, bleeding and pressure checks where required
• Basic optimisation of pump settings for stable flow and quieter running
• Functional testing to confirm radiators heat evenly and the system responds to controls

When this service is the right fit

This service is ideal if your heating is on but radiators stay cool, only heat up in patches, or take a long time to warm through. It also suits cases where the pump is noisy, seized, leaking, or repeatedly cutting out. Landlords and small commercial sites often use it to restore heat quickly and reduce call-backs.

What happens during the visit

The engineer will confirm the fault first, then isolate the electrics and heating circuit as needed. Depending on your system layout, this may involve a controlled drain-down or isolation at valves, followed by swapping the pump and checking associated components. The system is then brought back up, bled, tested, and adjusted so circulation is consistent across the property.

After replacement: performance checks and ongoing value

Once the pump is running correctly, you should see quicker warm-up times and more even radiator temperatures. You will also get clear guidance on recommended settings and any related issues spotted during testing, such as sticking valves, sludge risk, or recurring air ingress. If further optimisation is needed, the next steps can be planned without guesswork.
