Project Description

The building is a sheltered housing complex comprising of 48 flats all with elderly and vulnerable tenants. Through carrying out routine maintenance and reactive repairs it was identified that the existing plant was in extremely poor condition and inefficient. Of four boilers only three were operating, the tank fed DHW calorifiers were leaking badly and the automatic controls had failed so all equipment was operating at full load.

Initially the electrical supply to the Boiler House was increased to accommodate new 6kw, 3ph immersion heaters in the new DHW calorifiers. Once this supply was in place the DHW calorifiers were de-commissioned and removed from site by a specialist sub-contractor. The new cylinders were connected back to the existing system using pre-fabricated stainless steel pipe sections. The DHW system was connected back on to and the new electrical supplies connected to the immersion heaters. Through careful planning we were able to minimise the down time of hot water to two days and the heating remained on throughout.

Once hot water was re-instated to the building the heating plant was de-commissioned and removed again by a specialist contractor. LCC provided oil filled radiators to all properties for heating while the heating plant was inoperative. The 4 No Broag Quinta Pro boilers were installed onto a pre-fabricated frame with all associated pipe work and with the vast majority of pipe work for the heating system pre-manufactured off site, again with a view to minimising down time of the heating, we were able to minimise down time of the heating to four days. This included the pressurisation of the heating system via the installation of a new expansion vessel and pressurisation unit.

Once all equipment had been installed we completed the automatic controls installation complete with a web enabled BMS controller and control panel.
