Trace heating uses less energy to maintain temperature of domestic hot water
Published:  August 2008

Energy savings of up to 50% for maintaining the temperature of domestic hot water in distribution pipework are expected to be achieved using a single-pipe system with Raychem HWAT trace heating compared with a conventional recirculation system in the redevelopment of Epping Forest College Campus..
In addition, eliminating the need for secondary pipework achieves cost savings in space, material and installation and savings in installation time.
Aqua Mechanical Services, M&E contractor for the project, commissioned Astec Mechanical Services to supply and install the system to maintain water temperatures at 60°C and deliver instant hot water throughout the complex.
Astec, a distributor partner for Tyco Thermal Controls, which makes the Raychem system, supplied and installed 1800 m of trace-heating cable and 15 HWAT-ECO ‘smart’ controllers in the 3-storey academic building and in technology and theatre buildings which rise to five storey

Redefining zero carbon
Published:  June 2008


‘Our proposed definition recognises off-site renewables could play a part and also gives a big boost to community-scale technologies. This would have the added benefit of enabling much needed carbon reductions in the existing stock by enabling the distribution of low- or zero-carbon heat through district networks.
The full report is available on the UK-GBC web site.

‘The solutions we are pointing to are designed to ensure energy-demand reduction always comes first and on- or near-site renewables should be the focus for meeting energy needs.

Carrier Rental Systems keeps data centre up and running
Published:  July 2008

Two 450 kW chillers and a host of other equipment were provided by Carrier Rental Systems to control the temperature in a data centre providing vital billing functions for several major service providers while power feeds serving the fixed cooling installation were interrupted for checking. These power feeds could only be checked at weekends, and once the power was cut off, the air-conditioning system also had to be cut off.
