Why this happens in City Bowl
The City Bowl mixes Victorian homes, converted apartment blocks and modern high-rise living. Plant space is tight, roof and balcony placement is common, and body corporate rules usually govern where a unit may be mounted and how much noise it may make.
We see hot water heat pump not heating across domestic geyser retrofits, integrated hot water systems, pool plant and commercial installations. The diagnosis is the same discipline every time: prove the fault with readings before replacing anything.
