To be ready for tomorrow´s market, cost effective and environmentfriendly solutions have to be found today.
This has never been more vital than in hot water supply and distribution where energy consumption is a significant proportion of a buildings energy usage. Hot water supply without wasting water or power is a requirement of any modern hot water system. At the same time, the system has to be run on economically and maintenance-free. The Raychem HWAT and Eltrace Traceo-W single pipe systems delivers these vital requirements.
The hot water temperature maintenance system is a flexible and space-saving system.
The space requirement for pipes has been reduced, because no return pipe is present. Risers, shafts and openings can be minimised freeing space for other services. An existing building may have an extra storey or an extension added. The new part of the building can be connected to the hot water temperature maintenance system easily, rapidly and economically, without needing any hydraulic compensation. The existing recirculation system can be easily upgraded in sections, where appropriate. It is possible to let rooms or storeys to third parties without any problems, as separate cost invoicing can be provided for hot water usage.
