The project involved replacing an ageing plant room in the basement of the college, where access was severely restricted and space limited. These constraints ruled out traditional large-scale plant equipment and required a compact system that could be transported through narrow doorways without structural alterations.
The chosen system features four Modumax mk3 floor-standing condensing boilers (196 / 392V) delivering 1,532?kW total across eight modules. These are integrated with two Hamworthy Heating Powerstock PS500 indirect calorifiers to provide domestic hot water for the college.
Hamworthy Heating’s Modumax mk3 range is specifically designed with retrofit projects in mind. The modular format allows boilers to be dismantled and manoeuvred into confined spaces before being reassembled in position, providing the flexibility needed for heritage environments where plantroom layout and access present unique challenges. By combining the modular boilers with Powerstock calorifiers, the system delivers both efficient heating and a reliable domestic hot water supply for the college.
To ensure precision, the project team used Hamworthy’s 3D digital design tools to plan the plant room layout in detail. This approach enabled much of the pipework to be prefabricated offsite, which streamlined the installation, and ensured that new equipment could be delivered in stages and installed in a single operation.
“The 3D models allowed us to coordinate the plant room before we even stepped on site. It saved time and helped everything run efficiently. Careful delivery planning also meant the installation could be completed in one single day,” explains Geoff Bunton of Bunton M&E Services.
The completed upgrade now provides Corpus Christi College with a robust, futureproof heating and hot water system that improves efficiency, reduces emissions, and meets the demands of its academic community, all while preserving the integrity of its historic setting.
