CASE STUDY
A quiet transformation from steam to copper
Copper Industries worked around the clock to replace an antiquated steam-based set up with two 5,000l copper hot water generators at mid ulster hospital…
There’s a quiet sort of pride that comes from getting the job done right. No drama, no noise, just proper work being done by good people, all behind the scenes. At Mid Ulster Hospital, a heating system that had served since 1952 was finally put to rest. Not because it failed, but because the future wouldn’t wait. Hospitals can’t afford breakdowns, it’s as simple as that. With many different departments, hundreds of staff and a steady flow of patients every single day, failure is not an option. When hot water falters somewhere as important as a hospital, you can’t just fix the symptoms – you must get to the root of the issue.
And this wasn’t just any ordinary system. This was a steam-based setup installed shortly after Queen Elizabeth’s coronation – barely updated over the seven decades since its install, yet carrying the entire load of a busy, modern hospital. Yes, gas boilers had been added along the way, but it was essentially patching an aging vessel and hoping for the best. The writing was clearly on the wall. The hospital desperately needed a system that could deliver real performance, absolute reliability, and significant carbon savings – all without disrupting daily operations. That’s when Copper Industries and LB Cylinders got the call.
But here was the challenge. It had to be done in winter. In a live hospital. With zero downtime. So, we brought a solid plan. And plenty of warm clothing.The team installed two 5,000L copper hot water generators – one indirect, one direct – with a standby boiler for added resilience.
“We’re already seeing the benefits. The numbers don’t lie - it’s working and it’s putting us ahead of schedule for our 30% energy reduction target by 2030.”
It wasn’t just plug and play. We spent three days on site, working round the clock, problem-solving everything from pump resistance to isolation coil complications. And when everything finally came together, the transformation was remarkable.
The new system cut out the long duct runs that used to bleed heat. Boilers fired less frequently, saving substantial amounts of gas. And the hospital could move away from steam dependency. That shift alone dramatically improved efficiency overnight. But energy savings were just the beginning. Legionella and Pseudomonas aeruginosa risk? Gone. The copper system keeps water constantly moving, with no storage tanks or dead legs in the piping. That’s absolutely crucial in a healthcare environment, where patient safety simply isn’t negotiable. Then there’s the environmental benefit. The old steam system relied on heavy oil.
The new copper-based setup is fired by gas – cleaner, more responsive and far better aligned with sustainability targets. By 2030, the hospital is on track to exceed its 30% energy reduction goal. And by 2050, it will be well-positioned to achieve net zero. David Anderson, Energy and Environment Manager at Mid Ulster Hospital, said, “We’re already seeing the benefits. The numbers don’t lie – it’s working and it’s putting us ahead of schedule for our 30% energy reduction target by 2030.”
What really made the difference?
The consistency. Since the system was commissioned, the hospital has experienced smooth, uninterrupted service. Hot water is available exactly where and when it’s needed – without complications or concerns. It simply works. That’s precisely what a good upgrade should do – improve everything while hardly being noticed. This is part of a larger transformation. Along with solar panels, new PVC windows and decentralised heating, this installation represents one of many quiet revolutions happening where most people never look.
Hospitals are inherently complex. They don’t typically focus on infrastructure – until something fails. But this project demonstrates what can be achieved when good engineering combines with careful planning and a bit of nerve. The old steam system served its purpose. But its time had come. And now? Mid Ulster Hospital has a system that’s cleaner, more efficient and fully prepared for future demands. Because sometimes progress doesn’t arrive with a bang. It arrives with copper.
