Local Context
Why this happens in Parklands
High-volume modern housing where geyser retrofits are common. Very high wind exposure and constant salt-laden air off Table Bay.
We see heat pump losing heat 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.
