Heat pump not registered
The single most common Thermann problem we see is not mechanical — an unregistered heat pump loses warranty cover. Worth checking your paperwork now rather than at the point of failure.

Common Thermann faults in Geelong homes
Continuous flow flow-sensor faults
The unit fires intermittently or not at all on low-flow outlets. Usually the flow sensor or a partially closed isolation valve.
Element failure on larger tanks
The 250L and 315L tanks used in bigger Highton and Grovedale family homes see heavy cycling; elements are a straightforward stocked replacement.
Noisy heat pump operation
R-Series units are audible. Rattle rather than hum usually means mounting feet or a fan bearing, not a failing compressor.
When replacing beats repairing
Thermann parts are supplied through trade channels rather than held on every van, so an out-of-warranty tank needing multiple components is often more economically replaced than repaired in stages.
Our repair or replace guide sets out the full decision, and the Geelong replacement cost guide explains what changes the price. Symptoms are covered in common hot water problems and the hot water FAQ.
