My fan runs but there’s no hot water—what’s wrong?

Likely a compressor not engaging or a sensor/PCB issue. We test sensors/wiring, inspect the PCB and confirm refrigerant/pressures to resolve the fault.

What models do you service?

We work on SolarStar heat pumps, SuperFlow storage-displacement units, and Copperflow/TruFlow tank systems, plus solar split systems.

Saxon Heat Pump Repairs & Servicing Gold Coast

Gold Coast’s Saxon Heat Pump Specialists

Still running a Saxon SolarStar / SuperFlow storage-displacement heat pump or a Saxon tank with a heat-pump add-on? If you’ve got no hot water, lukewarm water, a PTR valve that won’t stop dripping, fan running but compressor won’t start, or constant cycling, we can help.
Todd’s Plumbing & Electrical provides same-day diagnostics, repairs and retrofit options for Saxon heat pump hot water systems across the Gold Coast. (Saxon ceased trading around 2010–2011, so parts can be scarce — we’ll advise the best fix or replacement path.)

Common Saxon Heat Pump Issues We Fix

No hot water / lukewarm water
Sensor/thermostat faults, compressor not engaging, refrigerant loss, restricted airflow, timer/supply issues. (A common field report is fan running but compressor not cutting in.)
PTR (TPR) valve constantly dripping
Occasional discharge is normal; steady flow suggests high pressure/temperature or a worn valve — we test/replace and confirm pressures. (Ageing Saxon tanks often show valve issues.)
Runs constantly / short cycles
Dirty/iced coil, blocked airflow, sensor/PCB faults, undersized or ageing unit — we clean, test and recommission.
Leaks around tank/coil
Older heat-exchange/copper-coil Saxon designs can develop pressure leaks in the coil and corrosion over time. We pressure-test, isolate and discuss repair vs. replacement.
Noise & vibration
Fan bearing wear, loose mounts, debris on evaporator, compressor strain — we rectify and balance.
Error/fault indicators
We read any available codes/indicators, ohm-test thermistors, check wiring/board and replace components where viable.

What made Saxon different (and what we service)

Saxon produced heat-pump and heat-exchange hot water systems (e.g., SolarStar heat pump, SuperFlow storage-displacement, Copperflow/TruFlow tanks) that were popular in QLD. Although the brand is discontinued (liquidation circa 2011), many units are still operating. We service the fan & coil, compressor & electrics, sensors/PCB, PTR/expansion valves, anodes & cylinder, condensate/drainage — and we can retrofit modern replacements when repair isn’t economical.

FAQs

Can you still repair Saxon heat pumps?

Often yes — but because Saxon ceased trading around 2010–2011, some parts are obsolete. We’ll quote repair if viable, or recommend a like-for-like modern replacement.

My unit’s fan runs but there’s no hot water — what’s wrong?

Commonly a compressor not engaging (sensor, capacitor, PCB or compressor fault). We test sensors/wiring and confirm refrigerant/pressures.

What models do you see most?

Legacy SolarStar heat pump / SuperFlow storage-displacement and Copperflow/TruFlow tank systems, plus solar split systems.

Should I repair or replace?

If the tank/coil is leaking or the compressor fails and parts are scarce, retrofit to a current, efficient heat pump can be smarter long-term. We’ll price both options.
