Calorifier Not Heating in Mulbarton Ext
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 Mulbarton Ext.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Mulbarton Ext is an extension of Alberton with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
