Heat Pump Icing Up in Meyersdal Nature Estate

Ice forms on the evaporator coil and does not clear between cycles. This page covers how we diagnose and repair it on heat pumps in Meyersdal Nature Estate.

This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.

Meyersdal Nature Estate is a security estate off Alberton where hot water plant is typically heat pump with buffer storage, plus pool heating on most stands. House sizes push multi-geyser or single large-storage layouts. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
