Hamworthy replaces boilers for college at Cambridge University
Gas bills for heating and hot water at St Catherine’s College in Cambridge have been reduced by 25% following the installation of new boilers and an upgrade of the heating system. Hamworthy Wessex ModuMax boilers were chosen on the basis of experience of neighbouring King’s College and replaced Hamworthy Lulworth L10 (1050 kW) steel boilers.
Robin Bunton of Bunton M&E Services, who has worked with the college for many years, selected and installed the equipment. It included three vertically stacking ModuMax boilers and factory-assembled pipe kites. A total of nine modules provide an output of 1980 kW, delivering heating for nearly all the college. Two 1000 l Powerstock calorifiers connected to the boilers provide an indirect hot-water solution.
Three months before the boilers were installed, Robin Bunton fitted eight MagnaClean magnetic filters to help clean the old system of dirt and debris to protect the new boilers and improve the efficiency of the system.
The new pipework for the system was fabricated offsite by Bunton M&E to speed up installation on site.
