Heat Pump Repair
in Caerphilly.
Repair enquiries are separate from planned servicing and should describe the symptom, when it began, any warning or fault code, whether heating or hot water is affected, recent power interruptions or building work, and whether the outdoor unit is obstructed or iced. A repair assessment may need to distinguish controls, electrical supply, circulation, sensors, valves, defrost, condensate, cylinder, emitter and refrigerant-system issues. Do not reset repeatedly or open sealed/refrigerant circuits; provide the model information and photographs only when safe, and arrange qualified diagnosis for electrical or refrigerant work. In heritage-sensitive locations, replacement equipment or altered external routing may require the same planning review as a new installation.

- Provide the full postcode, property type, approximate construction age, and whether the home is detached, semi-detached, terraced or a flat; these details help frame access and retrofit context.
- Share the heat-pump make, model, system type, installation date if known, cylinder or buffer-tank details, and the latest service or commissioning records.
- For a repair, note the exact symptom, fault code, affected heating or hot-water zones, and any recent electrical outage, plumbing change, insulation work or ventilation alteration.
- Keep access clear to the indoor unit, cylinder, controls and outdoor unit, and flag early if the property is listed, lies in a conservation area, or has restricted external access so planning and safe working checks can be considered.

for the enquiry.
What should I do if my Caerphilly heat pump shows a fault code?+
Record the code, the time it appeared and whether heating or hot water has stopped, then provide the make and model. Avoid opening the unit or repeatedly resetting it; a qualified diagnosis can establish whether the issue is with controls, power, circulation, sensors, defrost, condensate or a sealed refrigerant circuit.
Could Caerphilly heritage considerations affect an outdoor unit or pipe route?+
They can. Caerphilly Castle is a protected historic asset, and listed buildings or conservation-sensitive properties may require advice about siting, appearance and external alterations. Check the property’s designation and planning requirements before committing to a visible installation or replacement route.
