Heat Pump Not Heating Water in Wadeville
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 Wadeville.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Heavy industrial area with steam boilers and process heating 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.

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.
