Edwards Building
Preventing Boiler Dry Cycling to Deliver Long-Term Efficiency Gains
The Edwards Building, part of an NHS estate, faced significant inefficiencies in its boiler systems. Frequent dry cycling — when boilers fire unnecessarily without demand — was causing wasted energy, unnecessary wear on equipment, and increased operational costs. A reliable, efficient solution was required to protect critical heating infrastructure and support the hospital’s sustainability objectives.
WISE Controls delivered a bespoke integration that monitored and controlled boiler firing patterns in real time. By preventing unnecessary dry cycling, the solution reduced energy waste, improved system responsiveness, and extended the operational lifespan of the boilers. The result was a more stable and efficient heating system in Edwards Building, lowering both energy use and long-term maintenance costs.
“Having worked with WISE controls for many years now, I can say without a doubt that Phil and Mia provide us with an outstanding service, they regularly go above and beyond to keep the Royal Liverpool Hospital site running while taking the time to educate our technicians in the many complex systems on-site.”
