Local Context
Why this happens in Kirstenhof
Suburban homes close to the wetlands with damp winter conditions. Cooler, wetter winters on the mountain side with damp mornings affecting defrost cycles.
We see heat pump not switching on 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.
