Heat pumps · Priority

Heat Pump Leaking Water

Water pooling under or around the unit, sometimes continuously.

This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.

Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

What we find

Likely causes

Blocked condensate drain or tray
Perforated heat exchanger
Failed pump seal or union
Cracked pipework from freeze or vibration
Excess defrost condensate with no drainage path

Test sequence

How we diagnose it

Trace the leak with the unit isolated and pressurised
Pressure test the water circuit
Inspect the condensate tray and drain path
Check heat exchanger for cross-leak into the water side

FAQs

Frequently asked questions

What causes heat pump leaking water?

The usual causes are blocked condensate drain or tray, perforated heat exchanger, failed pump seal or union, cracked pipework from freeze or vibration. Which one it is can only be confirmed by measurement, not by symptom alone.

How do you diagnose it?

Trace the leak with the unit isolated and pressurised; Pressure test the water circuit; Inspect the condensate tray and drain path; Check heat exchanger for cross-leak into the water side. 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.
