Heat Pump Making Noise in Pretoria
Rattling, grinding, screeching or loud humming during operation. This page covers how we diagnose and repair it on heat pumps in Pretoria.
This fault is normally treated as scheduled work because the plant remains usable, but the fault will get more expensive the longer it is left.
Government buildings, hospitals, hostels and industry with large centralised hot water and boiler plant. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
