Transport for London embraces Rinnai continuous flow hot water system delivery at state-of-the-art training centre

Rinnai at TFL

Transport for London (TfL) has installed the total Rinnai water heating system solution of continuous flow water heaters, BMS controls, remote monitoring facilities, Nexus electrolytic scale inhibitors, flexible flueing systems and more ancillaries, all underscored by continuing energy and carbon analysis of comparative product systems.

Transport for London (TfL) has installed the total Rinnai water heating system solution of continuous flow water heaters, BMS controls, remote monitoring facilities, Nexus electrolytic scale inhibitors, flexible flueing systems and more ancillaries, all underscored by continuing energy and carbon analysis of comparative product systems.

The site is the TfL Ashfield House Training Centre in West London and the system supplied comprises - 4 x N Series Sensei 1600i units on cascade frames with an additional 500L buffer vessel. 

The new system will service all the hot water needs throughout the building. Provided there are constant supplies of water and gas Rinnai Continuous Flow Hot Water Systems will deliver a constant flow of temperature controlled hot water.

The system also includes multiple valve kits and unvented cylinders to support compliance and enable best practice, in system design. The innate technology provides high efficiencies and remote monitoring capabilities by the seamless integration and monitoring with the onsite BMS.

The new N Series arrangement incorporates connectivity controls to ensure each appliance is visual and addressable on the BMS system. The water heater array will provide over 3000 litres of continuous hot water at 60 degrees.

The new hot water heating system at Ashfield House was designed by leading building engineering consultants Norman Disney & Young. Installation was carried out by Maracom, a multi-disciplined installation specialist, established since 1951.

Theodore Jones, CEng MCIBSE, is Infrastructure Manager for TfL, and he commented on the organisation’s approach to its hot water needs and facilities: “We chose to install a cascade of Rinnai’s N Series water heaters to provide a robust and resilient system, able to cope with periods of high hot water demand in this 9-storey building.  The N series units are compact and lightweight, affording ease of transportation to the 9th floor plant room.  The inherent modularity of this solution allowed for a rapid installation, and the finished system exhibits a smaller floor footprint than traditional HWS plant.  This installation supports TfL’s strategy of deploying the most energy efficient and reliable plant in our estate.”

Comments Chris Goggin for Rinnai, ‘This installation contains many facets of our total product offering, all of which is aimed at maximum efficiency in both engineering and financial terms. On demand limitless hot water with precise, controlled temperature is the cornerstone of our offering today to all sites of any size or use.

“At Ashfield House we have supplied the new N series, Nexus scale protection, Remote Monitoring, common header flues, cascade frame leading towards complete system efficiency, interoperability, compliance with all legislation or Codes and Standards of Practices.”

TfL is the integrated transport authority responsible for meeting stated strategies and commitments on transport in London. In daily effect TfL manages the day-to-day operation of the Capital's public transport network and manage London's main roads.

TfL’s programme of transport capital investment is one of the world's largest. It is building the Elizabeth line, modernising Tube services and stations, transforming the road network and always aiming for greater safety in all forms of transport around London, one the world’s biggest and busiest cities.
