Commercial Hot Water System Failure in Craighall Park
The site loses hot water during peak periods while plant appears to be running. This page covers how we diagnose and repair it on hot water systems in Craighall Park.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Craighall Park sits within the Rosebank belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
