Prefab heating solution scores top marks I
N THE many UK schools that rely on commercial boiler plant for their heating, carrying out routine
designed rig system in each plantroom, having used the off-site fabrication service successfully on previous projects. Using a rig system to speed up
refurbishments scheduled for completion within the fixed timeframe of the summer holidays, this can present challenges for both estates managers and contractors. So when the old sectional cast-iron
boilers needed replacing in both of the plantrooms at Glebe Primary School in Rayleigh, Triglyph Engineering Services recommended using prefabricated heating equipment as a solution to rapid installation. This would meet the school’s key requirements for improved heating reliability and efficiency as well as providing faster, easier installation. “Installing multiple condensing boilers
rather than one larger output unit helps maximise the heating efficiency and reliability as well as ensuring easier future maintenance,” explained Spyros Sergiou, M&E Consultant at Triglyph Engineering Services. He specified two Remeha Quinta Pro 115 condensing boilers on a bespoke-

installation of multiple condensing boilers is not a new concept. But the standard rig unit could potentially require on-site modifications, especially if there are space limitations. In contrast, a bespoke rig system can be designed to meet each project’s individual project and site requirements – from output to physical size. This avoid the ‘one-size- fits-all’ approach traditionally associated with prefabrication. At Glebe Primary School, Triglyph were
able to overcome access restrictions via the bespoke rig system at the design stage, avoiding potential challenges at a later stage. “The boilers needed to pass through a
double set of doors to enter the plant room,” said Spyros. “This was accounted for in the design so that, when the boilers were delivered into the plant room in the pre-assembled wheeled unit, they fitted in neatly and just needed to be plugged in. It couldn’t have been more straightforward.” When installing condensing boilers onto old systems, the quality of the water can
affect boiler operation and longevity. This can be addressed with the bespoke rig unit, as Spyros explained: “The heating system at the school is
around 20 years old. To achieve hydraulic separation and so ensure good condition water, we integrated a plate heat exchanger and air and dirt separators into the rig design.” Using a prefabricated heating solution
like the bespoke rig system reduces the intensity of skills required on-site. For schools, this provides more flexibility on the timing of refurbishment projects as the safer conditions, combined with the rapid changeover period, enable boiler replacements to be carried out outside of the holiday period. A further advantage of the detailed
forward planning process is that the cost, size and specification are all fixed and in place before the bespoke rig was built. For schools like Glebe Primary School, this helps keep the project on time and on budget.
