Jointing Technologies, a Distributor Partner of Tyco Thermal Controls, has supplied and installed a Raychem HWAT self-regulating heat-tracing system for hot water temperature maintenance at the brand new Lymington New Forest Hospital. The temperature maintenance contract was placed through Thermal Coverings, the project’s insulation contractors, for a system that enables a single pipe hot water system to be employed throughout the hospital.
Raychem HWAT is a simple, effective and intelligent system that ensures instant hot water is available at every hot tap, including those on ‘dead legs’. It comprises self-regulating heating cable technology and smart controllers. At Lymington New Forest Hospital over 4000 metres of self-regulating cable is being installed along the hot water pipes to apply just the amount of heat required to maintain the water temperature between 50°C and 55°C. Raychem HWAT-ECO smart control units are employed to limit the power output of the heating cable in accordance with the building’s requirements. Easy-to-programme and BMS compatible, these controllers also monitor the boiler temperatures to ensure the heat-tracing system is only fulfilling a temperature maintenance function - not water heating. This temperature maintenance solution not only delivers significant energy cost savings over conventional re-circulation systems but, in eliminating return pipework, also offers space, material and installation time/cost savings too.
The £29m Lymington New Forest Hospital is being built by Ryhurst Ltd, as a PFI project for the New Forest Primary Care Trust, and is due to open in December 2006.

There is an obvious need for the industry to be more energy efficient and pay more attention to the ways in which energy is both used and wasted. Do you think we have the products on the market to meet our needs?
