Heat pump not heating properly and what to tell the engineer
When a heat pump is running but the house feels cold, it can be difficult to know whether the issue is the unit, the controls or the heating system around it. A few clear observations can help an engineer plan the investigation.
Forward Thermal and Flow provides heating diagnostics and heat pump servicing. Tell us what has stopped working and we can discuss the most appropriate next step.
Describe what is affected
Is there no heating anywhere, or is one room colder than the others? Is hot water available? Does the problem happen all day or only at certain times? Explain whether it began suddenly or has become worse over several weeks.
If someone else is arranging the visit, pass on the resident's description rather than guessing at the cause. A short account of what actually happens is more useful than assuming a particular part has failed.
Photograph the display
Take a clear photograph of any fault message and the equipment's make and model label. Note when the message appears and what the system was doing at the time. Keep any previous repair notes available too.
Avoid repeatedly resetting the equipment or changing several settings while you wait for advice. Follow the user manual for permitted checks, and leave covers, electrical components and refrigerant work to a suitably qualified engineer.
Explain recent changes
Tell us if there has been a power interruption, other heating work, a change to the controls or a leak. Also mention whether the system has recently been serviced and whether the problem was present beforehand.
Arrange a diagnostic visit
The next step may involve checking controls and water circulation as well as the heat pump itself. A diagnostic visit helps establish what further work is needed; parts and repairs depend on the findings.
Send Thermal and Flow your postcode, contact details, equipment information and a brief description of the fault. Explain whether you currently have heating and hot water so we understand the situation when discussing availability.
