Heat Pump High Pressure Fault in Boksburg
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 Boksburg.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Manufacturing, food processing and logistics sites with gas and diesel boiler plant. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

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 Boksburg?
