Boiler Losing Pressure in Melrose Estate
System pressure falls and the boiler needs repeated topping up. This page covers how we diagnose and repair it on boilers in Melrose 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.
Melrose Estate is an estate development adjoining Rosebank, with standardised heat pump and geyser installations fitted at build and now reaching first major service intervals. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
