Tick Tock, Time Bomb: The Dangers of Neglected Unvented Cylinders

 

Blog Content

 

Set amidst the towering heights of Salford Quays, these luxury apartments' sleek, modern architecture evokes a sense of sophistication and cosmopolitan living. Located just a stone's throw from MediaCityUK, the area bustles with young professionals and city dwellers eager to take advantage of the convenience and amenities of this vibrant neighbourhood. On the 13th floor of one of Salford Quays' most exclusive addresses, the DDWilson team embarked on our latest heating mission - installing a new electric boiler system. Surrounded by the towering pillars of urban living, we got to work, determined as always, to deliver comfort and safety to the residents of this stylish community.


The Discovery

Upon visiting the apartment in Salford Quays, our heating engineer Tristan made a concerning discovery - the existing unvented hot water cylinder had not been adequately maintained for some time. Though these cylinders provide outstanding performance when cared for properly, neglecting maintenance can be extremely dangerous. The pressurised water inside an unvented cylinder must have the means to safely expand when heated, controlled by the expansion vessel and pressure relief valves. Tristan's expert eye saw the telltale signs of neglect in this case. The pressure relief valves malfunctioned and could no longer safely discharge excess pressure. Even more troubling, hastily wiped-away scorch marks around the cylinder connections indicated that dangerously high pressure had caused steaming water to leak. It was clear to the team this long-neglected unvented cylinder posed a severe safety hazard to the building's residents. Urgent replacement would be needed.


The Dangers

Upon closer inspection, Tristan unearthed some troubling signs – malfunctioning pressure reliefs and indications of frothing steam hidden under hastily erased scorch marks. These were unmistakable red flags that voiced the urgency of intervention. The peril of neglecting such maintenance was all too apparent. Without it, the pressurised water inside the cylinder could pose a significant hazard akin to a ticking time bomb. Proper expansion is the key to safety in these systems, regulated by the all-important expansion vessel and its pressure relief features.


If the pressure relief valves fail, the pressure can build to dangerous levels. An explosion can occur, spraying superheated water and steam throughout the building. The scorch marks indicated previous failures, which were covered by whipping away the marks. 


Frothing and bubbling inside the cylinder are also very concerning. The Frothing and bubbling is likely due to limescale buildup corroding the metal and releasing hydrogen gas into the water. A spark could cause a catastrophic explosion. The lack of maintenance created an urgent hazard that threatened the safety of all the building's residents. Quick action was required to isolate and replace the faulty system before disaster struck.


Taking Action

When Tristan first visited, he immediately took measures to isolate the potential hazard, ensuring the safety of the building's residents. The isolation involved shutting off the water and power supply to the faulty, unvented cylinder and advising residents to refrain from using hot water until the issue could be addressed appropriately. Recognising the urgency of the situation, the team at DDWilson sprang into action to source a replacement system. We have longstanding relationships with the top manufacturers of electric boilers and unvented cylinders, allowing us to quickly select an appropriate new model that would meet the needs of this building. Within days, we had the latest electric boiler and unvented cylinder on order and ready for installation. The safety and comfort of our customers are always the top priority. We minimised disruption and risk by isolating the faulty system and rapidly arranging for a new one. Our expertise and responsiveness demonstrate our commitment to delivering the best possible service.


Installation Day: A New Beginning

With the new system in hand, Tristan is back on site, ready to bring warmth and safety back to the bustling life in Salford Quays. Installation days like these are what we live for at DDWilson – the opportunity to ensure the comfort and well-being of our communities. 


The team works diligently, carefully removing the old, faulty system. Years of neglect have taken their toll, but Tristan and his crew carefully handle the aged parts. This system served its time, but now it's time to retire it safely. With the outdated boiler and cylinder removed, the real work begins. Meticulously following best practices, the team installs the new system, carefully connecting all parts securely and correctly. Tristan inspects their work, ensuring the highest quality installation. 


After a long day of intense focus, the moment of truth arrives. Tristan flips the switch, firing up the new boiler for the first time. As the system hums to life, warmth floods the apartment. The residents sigh in relief, welcoming the return of their heat and hot water. Tristan and his team tidy up, eager to see the new system sustain the comfort and safety of Salford Quays for years to come. As they pack up, residents stop in to share their gratitude. Installation days like this remind the DDWilson team why they do what they do - to keep their community warm, safe, and happy.
