Custom built Zurich HIU's supplied for Cambridgeshire apartments

A residential conversion project completed in a small Cambridgeshire town with the mechanical services contractor undertaking the installation of custom built versions of GF Piping Systems’ Zurich range of heat interface units (HIU’s): delivering both very efficient space heating and continuous hot water for the occupants of the apartments.

The W2 Building in Great Cambourne was formerly an office block, but has been refurbished and reconfigured by developer, Aspens, to create 18 high specification dwellings across the three floors.

Gowing & Hunt has undertaken the installation of the property’s building services, which includes a centralised boiler system with modern HIU’s – tailored to suit the property’s special requirements, providing the ideal delivery solution.

The twin plate heat exchanger units had to be customised because the utility cupboards where they are fitted are compact, the standard Zurich design was re-engineered to provide top primary connection and incorporated the flushing bypass valve within the casing. With the cover fitted the special Zurich HIU’s measure 672mm wide by 790mm tall, while they are just 250mm deep. They offer 10 kW output in heating mode and 45 kW for direct hot water supply to the apartments’ kitchens and bathrooms.

Gowing & Hunt, commented: “The project was originally specified by ourselves – including the decision to make use of a central boiler plant heating system, with three condensing gas boilers plus a booster set in the plant room and featuring the use of twin plate HIU’s.”
