DATA SPLIT Heat Interface Unit (HIU)

Our next generation intelligent HIUs provide:

• The ability to network with other intelligent heat interface units, working as a team to improve system efficiency and reduce peak primary system load by as much as 25%
• Web based data logging and controls enable remote commissioning and
  fault diagnosis
• Small enough to fit into a standard kitchen cupboard
• Up to 75kW Domestic Hot Water (DHW) and 25kW Central Heating (CH) outputs
• Primary return temperature limited to a maximum of 30°C (DHW only)
  Heat loss from casing <50W
• Dimensions: 560mm W x 305mm D x 470mm H 
• The Split configuration allows the HIU to be locked away from tampering hands

The DATA SPLIT HIU is based on the same components and controls as the DATA HIU, however we have reconfigured the layout to allow the expansion vessel, safety relief valve, pressure gauge and filling loop to be fitted remotely.

The DATA SPLIT provides domestic hot water and central heating in properties connected to a district heating system using a central boiler.

It is easiest to think of the DATA SPLIT as a combination boiler, running off heat from large pipes throughout the development, rather than a gas supply in each apartment. Occupants are charged for units of heat, rather than units of gas, and the charge is calculated by a heat meter which measures energy use. The DATA SPLIT is part of our range of next generation of Heat Interface Units, that deliver the benefits outlined above but are also capable of communicating with each other, with the occupant and with the buildings computerised management systems; enabling greater efficiency throughout the entire system and greater control over the function of the unit. The designers at Thermal Integration have been at the forefront of HIU technology for over twenty years, and the DATA SPLIT (Intelligent Heat Interface Unit) is built on this experience.

Features and Benefits

• Inter-networking of all DATA SPLIT units within a development to enable site wide adjustments to match loads to primary circuit heat availability
• Web based interface and online dashboard for remote commissioning, monitoring, control adjustments, performance visualisation, fault detection and diagnosis
• Compact design with no need for clearance either side for servicing. Allowance made for extra options, yet small enough to fit into a standard kitchen cupboard
• Instantaneous hot water up to 65kW (standard model) 75kW (Plus Model)
• Indirect central heating up to 25kW
• Range rated outputs, using specifically sized plate heat exchangers for increased or decreased outputs
• Primary return temperatures can be limited
• Sensors for temperature, pressure and flow rate allow the system to monitor performance and detect fault conditions locally, or on the district heat network
• The latest stepper motor valve technology allows the system to react rapidly, thereby maintaining accurate control over domestic hot water temperatures
• Pre-install plumbing jig complete with isolation valves to allow pipework on site to be completed prior to the final installation of the unit
• Primary circuit trickle flow can be set to maintain heat within the unit. When in Economy Mode it allows the unit to go cold following one hour of inactivity, preventing unnecessary use of metered energy
• Insulated removable EPP casing with less than 50 Watts standby heat loss; ensures the unit can be maintained at temperature with little impact of metered energy use
• Sterilisation programme raises the DHW temperature periodically; preventing build-up of Legionella bacteria
• Built-in security feature for landlord isolation
• Pump exercise function
• Site specific factory calibration of controls to predefined settings
• Customised connections top/bottom (standard connections are all at the bottom with space behind the HIU for pipes to be routed to the top
• External expansion vessel, safety relief valve, pressure gauge and filling loop allowing the HIU to be locked away from the end user whilst still giving them access to the serviceable components
• WRAS approved (components)

Options

• Various heat meter and billing options
• Wireless heat metering compatible with on-board or aftermarket billing systems
• WiFi and Ethernet enabled with roaming 3G capability
• Patented anti-tamper security fixings on casing and heat meter
• Secondary hot water recirculation pump (external to the casing)
• Air and dirt separation (external to the casing)
• Water hammer arrestor (external to the casing)
• External cold water meter
• Top pipework kit
• Flushing bypass
• Rear mounted expansion vessel
• Landlord security functions
