Heat Pump Repairs
Fault finding for heat-pump systems with heating, hot-water, controls, circulation and accessible system components checked before deciding what needs repair.
Heat pump fault finding and repairs
No heating
Diagnosis where the heat pump is running poorly, not starting or not delivering useful space heating.
Hot-water faults
Investigation where cylinder heating or hot-water recovery is not operating as expected.
Flow and circulation
Checks where poor flow, air, pressure or heating-side circulation may be contributing to the fault.
Controls and sensors
Assessment of control settings and accessible sensor/control symptoms where they affect operation.
Error conditions
Practical investigation around displayed faults rather than simply resetting the unit repeatedly.
System-side faults
Identification of issues in valves, pumps, filters, emitters or controls that can make a healthy heat pump appear faulty.
Check the whole system before blaming the outdoor unit
Heat-pump performance depends on the heating circuit, emitters, controls and hot-water system as well as the heat-pump unit itself. Fault finding should separate a refrigerant/manufacturer issue from a heating-side problem before parts are recommended.

Heat Pump Repairs FAQs
Can you repair every heat-pump fault?
We can investigate the system and heating-side causes. Some faults may require manufacturer-specific parts or specialist refrigeration support; we will say so rather than overstate the scope.
Why is my heat pump running but the house still cold?
Possible causes include inadequate emitter output, low flow, control settings, weather compensation, circulation problems or an equipment fault.
Should I keep resetting a fault code?
Repeated resets can hide the symptom without solving the cause. If a fault returns, it should be investigated.
