The calorifier receives steam or hot water but the stored water stays cold. This page covers how we diagnose and repair it on hot water systems in Greenstone.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Retail, medical and residential development with centralised hot water systems. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
