Nexus units from MHS Boilers specified for the Queensridge Court

(17/08/2010)

The Queensridge Court, a £12 million development for the over 55s in Sandwell, West Midlands, features 33 two-bedroom shared ownership apartments, 38 two-bedroom rented apartments, as well as 16 one-bedroom apartments for older people with mental health needs, along with communal facilities including a shop, restaurant and gym.

87 Nexus Bitherm wall-mounted units with built in plate heat exchangers, three Ultramax 120kW wall mounted condensing boilers and three Ultramax R602 200kW floor standing condensing boilers have been combined to create an energy efficient district scheme at the Queensridge Court.

Brian Taft, Senior Project Manager, for contractors SPI Limited, specified the Nexus units. He said: “We chose the Nexus units from MHS Boilers because they were both cost effective and had integrated plate heat exchangers. This eliminated the need for individual hot water storage cylinders in each property – freeing up space for the occupant. Additionally, the Nexus units don’t need annual servicing, which reduces ongoing costs – representing good value for money.”

Queensridge Court is being built in partnership with Sandwell Council and the Housing and Communities Agency for Housing 21 by SPI Limited. The M&E Consultant is Faarup Associates and the main contractor is Thomas Vale Construction.

With the growing popularity of district, network or community heating systems, MHS Boilers has developed a range of heat interface units which provide the link between a community heating system and a dwelling or small business unit. Whether the requirement is for a direct type unit or an indirect unit, for build-into-the-wall or for wall-hanging, with or without heat or water metering or with connections top/bottom or all on one plane – MHS Boilers has a comprehensive solution with Nexus.

Chilled water metering is also possible for developments where cooling from a central source is also provided. MHS Boilers can also provide the central boiler plant with gas condensing boilers available up to 1.9MW each. And much larger outputs are available as multiple boiler installations.

The Nexus range is split into build-into-the wall and wall hanging types and then subdivided further:

Nexus Diatech Units are build-into-the wall versions and are useful where the dwellings do not have a dedicated cupboard or enclosure for the siting of the heat interface unit.

Nexus Futura Units are fully cased wall mounted types with lockable doors/access panels.

LF versions are available in both Diatech and Futura types and these variants are specifically designed to operate with lower central system flow and return temperatures which are ideal for realizing better efficiency from the use of condensing boilers as the community heat source.

Bitherm types indicate that the unit is an indirect heating version and includes a heat exchanger for complete hydraulic separation of the dwelling’s central heating circuit from the community system.

Conter Zone Distribution Units are build-into-the-wall type units which can distribute and meter the supply of any or all of the following services: central generated heating, centrally generated hot water, cold water or chilled water.

MHS Boilers can also produce special units to meet specific requirements such as larger capacities or the inclusion of underfloor heating coil manifolds etc.

Heat Meter: CE marked Turbine type 1.5m3/h flow, class C, with liquid crystal display and long life battery. Upon request, equipped with data transmission cable for centralised consumption data reading (M-Bus).

Water meters: CE marked turbine volume flow meter 1.5m3/h flow.
