Heat Pump Not Heating Water in Roodepoort
The unit runs but water stays cold or only reaches lukewarm temperatures. This page covers how we diagnose and repair it on heat pumps in Roodepoort.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Broad residential base with light industrial parks and a large number of ageing geysers and early heat pumps. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

What we find here
Likely causes
- Low refrigerant charge from a slow leak
- Failed compressor or start capacitor
- Fouled evaporator restricting airflow
- Faulty water temperature sensor holding the unit off
- Reversing valve stuck in the wrong position
How it is confirmed
Diagnostic sequence
- Measure suction and discharge pressures against ambient
- Check compressor current draw versus nameplate
- Verify sensor resistance against the manufacturer curve
- Measure water delta-T across the condenser

FAQs
Frequently asked questions
What causes heat pump not heating water?
The usual causes are low refrigerant charge from a slow leak, failed compressor or start capacitor, fouled evaporator restricting airflow, faulty water temperature sensor holding the unit off. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Measure suction and discharge pressures against ambient; Check compressor current draw versus nameplate; Verify sensor resistance against the manufacturer curve; Measure water delta-T across the condenser. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
