Office Block, London

Main Boiler Room Update

The heating and hot water plant contained in the existing Boiler Room at the office block was at the end of its useful life and was in need of complete replacement.

SJP Mechanical Services Ltd were commissioned to upgrade the plant to modern energy efficient equipment. The works included the provision of three floor standing condensing boilers serving a low loss header. One constant temperature and two variable temperature secondary heating circuits were taken off the low loss header to serve all areas of the office block. Two gas-fired condensing hot water heaters were installed to supply all areas of the office block and were complete with de-stratification pumps. All circulating pumps were electronically speed controlled and the entire pipework system was insulated, and colour coded. A complete new Trend based control system was installed complete with a wall mounted control panel and wiring system. The heating system was thoroughly flushed out and the completed system dosed with a suitable corrosion inhibitor and biocide and the hot water system chlorinated. The complete installation was commissioned, regulated and handed over to the office block in full operating order. The Contract was completed on time, within the agreed cost and in a nine-week contract period whilst the office block was fully operational.
