Heat Pump High Pressure Fault in Roodepoort West
The unit locks out on a high pressure error, often after running for a while. This page covers how we diagnose and repair it on heat pumps in Roodepoort West.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Workshops and light industrial units with small boiler and hot water plant. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

The usual causes are poor water flow through the condenser, scaled heat exchanger, overcharge of refrigerant, non-condensables in the circuit. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Measure water flow rate and delta-T; Check condenser approach temperature; Verify charge by weight; Inspect strainers and valve positions. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Roodepoort West?
