The DATA Extra HIU, Installation Instructions DE2, 12th August 2021
Introduction
The DATA Extra HIU enables us to take the functions of our flagship twin plate DATA HIU and increase the heating output to cater for
commercial or industrial applications. The basis of this HIU is our SLIM hot water only HIU and then we add a heating plate heat
exchanger and Danfoss pressure independent control valve with a Novocon Actuator for the heating side of the HIU. Both the heating
and hot water controls are linked to our Node-iHIU system and can be accessed remotely for monitoring and adjustment.
The fully insulated HIU is enclosed within a white steel enclosure designed to keep the overall footprint of the HIU to an absolute
minimum. If required, the expansion vessel, safety relief valve, filling loop and pump are mounted external to the casing, allowing the
HIU to be fitted out of the way, with key components mounted in a more accessible location.
The heating installation must be equipped with a correctly sized expansion vessel and safety relief valve fitted between the HIU
and any isolation valve on the heating circuit. It is also advisable to fit a filling loop and pressure gauge to the heating system, in
a location convenient for the end user to access and top-up the central heating system. Refer to the chapter on "Installation
Requirements" for more information. Contact Thermal Integration for more information on parts availability and advice on
system safety.
