Central Heating Problems [We Fix]
Radiators Not Heating Up
Cold spots can have several causes, including trapped air, valve problems, restricted flow, sludge, pump issues or system balance. We diagnose the cause before recommending work.
Possible Pump or Circulation Fault
Poor circulation can be linked to the pump, controls, valves, air or system restrictions. We test the system before recommending repair or replacement.
Leaking Radiators
Leaking radiators can cause damage to your property. We repair or replace radiators to stop the leak and restore heating.
Thermostat Problems
If your thermostat isn't controlling the heating properly, we can diagnose and fix or replace it for accurate temperature control.
Noisy Heating System
Banging, knocking or gurgling can be linked to trapped air, flow conditions, pump issues or boiler faults. We inspect the cause before recommending work.
Heating System Balancing
If some rooms are hot while others are cold, your system needs balancing. We adjust radiators for even heat distribution.
Common Central Heating Issues
Air in the System
Air bubbles trapped in radiators prevent hot water from circulating properly. Radiator bleeding releases the air and restores heating.
Sludge Build-up
Over time, sludge and debris accumulate in radiators and pipes, blocking flow and reducing efficiency. A power flush cleans the system.
Pump and Circulation Checks
If radiators are not receiving heat, we check the pump, controls, valves and system flow. The correct repair depends on the findings.
Faulty Thermostat
Thermostats can fail or lose calibration, causing heating to turn on/off at wrong times or not respond to temperature changes.
Leaking Pipework
Corroded or damaged pipes can leak, reducing system pressure and causing heating loss. We locate and repair leaks.
Failed Motorised Valve
Motorised valves control which part of the system receives hot water. If they fail, heating or hot water may not work.
