What We Service on "Vulcan + Heat Pump" Systems
Note: Vulcan is a Rheem brand focused on gas/electric storage. Heat pumps are offered under Rheem and other group brands, which is why many "Vulcan heat pump" jobs are actually mixed-brand setups.
Heat Pump Unit
We service the fan/evaporator coil, compressor, sensors/thermistors, PCB/controller, wiring, and condensate drainage.
Tank & Plumbing
We check and replace PTR/expansion valves, tempering valves, anodes, cylinder health, pressure limiting, and drainage.
Controls & Tariffs
We configure timers, off-peak circuits, and PV-friendly schedules to optimize efficiency and cut your running costs.
Why Choose Todd's?
Brand-agnostic heat pump expertise: Rheem/AmbiPower, Thermann, Stiebel, Rinnai, Sanden CO₂, Midea/Chromagen and more.
Vulcan storage know-how: We understand the plumbing, valves and tariffs these tanks run on (e.g., 50–400 L electric; 135/170 L gas). If your add-on heat pump is uneconomical to fix, we quote a clean upgrade from a Vulcan tank to a modern, efficient heat pump.
Common Issues We Fix
Here are the most common faults we diagnose and repair on Vulcan storage systems paired with heat pumps.
No hot water / lukewarm
Sensor/thermostat faults, compressor not engaging, refrigerant loss, restricted airflow, or timer/tariff mis-set.
PTR (TPR) valve dripping
Steady flow suggests pressure/temperature is too high or a worn valve; we test/replace and confirm pressures.
Runs constantly / short cycles
Dirty/iced coil, low ambient performance, control faults; we clean, test defrost and recommission.
Noise & vibration
Fan bearing wear, debris on evaporator, loose mounts, or compressor strain.
Error codes
We read brand-specific codes (Rheem/Thermann/Midea/Stiebel/etc.), test thermistors, wiring and PCB, and replace failed parts.
High power use
Booster/element overuse, dirty coil, scale, or poor timer setup; we optimise for off-peak/PV.
