KINGSPAN RANGE PREMIUM HOT WATER PRODUCTS HEAT INTERFACE UNIT PERFORMANCE When it comes to delivering what our customers want, the top priority is performance - it s key to providing maximum operating efficiencies and fast hassle-free installation. HIU s deliver heat that has been generated from a centralised heating plant to apartments. They maximise and optimise the whole system s performance to provide high levels of heating comfort in every room and copious volumes of hot water for washing, bathing and showering. PREMIUM Kingspan Range products only feature the highest quality components that are rigorously tested to ensure they provide safe, dependable hot water and heating for each dwelling. KINGSPAN RANGE HIU The Kingspan Range HIU is an ultra-high performance indirect Heat Interface Unit that provides precisely-controlled economical heating and hot water to the apartment, combined with the maximum level of control, to guarantee the lowest system return temperatures possible. This ensures a very high system operating efficiency, which in turn means lower running costs. The Kingspan Range HIU will provide the apartment with all of its heating and hot water needs. In principle, it acts as gas combi boiler without a flame or burner. All heat to run the HIU is provided by the centralised heating boiler. EXPERTISE Our team of technical experts contains a broad spectrum of skilled professions, including engineers with experience in the construction industry, accredited system designers, SAP assessors and people with practical plumbing experience. A choice of units with heating and hot water outputs to suit all types and sizes of apartments, ensures that the demand of achieving a high level of performance with maximum economy will always be satisfied. 3

KINGSPAN RANGE PREMIUM HOT WATER PRODUCTS THE HOT WATER PEOPLE PRECISE CONTROL FOR WHOLE SYSTEM EFFICIENCY Key Features Compact Design Fully Modulating for High Efficiency Plug and Play Commissioning The Kingspan Range HIU has been developed to achieve outstanding levels of efficiency and economy in the property by using a high performance control interface that also helps to optimise the whole building s heating system performance. The Proportional Integral Derivative (PID) Controller combines with the Pressure Independent Control Valve (PICV) with electric actuator and the two high performance Plate Heat Exchangers (PHE) to ensure that the system always operates at its optimum efficiency, so that heating comfort and high volume hot water performance are guaranteed, even when demands on the system fluctuate. This high level of control also ensures that very low primary system (district) return temperatures are maintained, giving substantial energy savings. INDIRECT FOR SYSTEM INTEGRITY The Kingspan Range HIU is an INDIRECT HIU which means that the two plate heat exchangers keep the secondary (apartment) heating circuits totally separate from the primary (district) heating circuits. Not only does this provide a pressure break, but also ensures that if there is a leak on the apartment heating system, the whole building system will not drain down. Hot Water Safety Tempering Feature Fast Hot Water Demand Response Time Up to 16 bar Primary System Operating Pressure Scale Reduction Feature Copious volumes of Domestic Hot Water Domestic Hot Water Priority Low District Return Temperatures Provision for Heat Meter of your choice Precise setting of Heating and Hot Water Temperatures Pressure Break via Two Plate Heat Exchangers Suitable for Single - or Two-Zone Heating Systems No Compression Joints Automatic Fault Diagnostics Easy Access to All Components for Servicing Suitable for Radiators or Underfloor Heating 5
Hot Water Energy Storage KEY COMPONENTS KINGSPAN RANGE HIU S PICV with Electric Actuator PID controlled proportional modulation of district supply regardless of pressure fluctuations in the district heating system. The PID Controller Uses information from various sensors within the HIU and from the room thermostat to control and optimise the flow rates and temperatures of the hot water within the system. The PID Controller is the brains of the system that ensures precise central heating and domestic hot water temperatures are maintained within the apartment, whilst at the same time ensuring that as much heat as possible is scoured from the water in the district system before it is returned. The result is that you have one of the most effective and efficient heating systems available. Diverter Valve PID controlled hot water or heating with hot water priority. Plate Heat Exchangers High capacity for ultimate performance and control. A-rated Pump PID controlled proportional modulation of apartment central heating. Hot Water Safety Valve Fail safe protection against ultra high domestic hot water temperatures. 6

Hot Water Energy Storage THE HOT WATER PEOPLE WHAT MAKES THE KINGSPAN RANGE HIU STAND OUT FROM THE CROWD? ULTIMATE HEATING AND HOT WATER COMFORT IN THE APARTMENT - MAXIMUM EFFICIENCY AND ECONOMY FOR THE WHOLE SYSTEM. Proportional Integral Derivative (PID) Controller The PID controller with temperature and flow sensor inputs, maintains the efficiency of the HIU. It switches to DHWS on demand and maintains stable temperatures for both the HTG and DHWS, even under varying demand conditions. The PID logic is also very clever in that it is dual-speed, which means that it reacts to demand by accelerating or decelerating response, to achieve and stabilise the set point quickly. Pressure Independent Control Valve The integral PICV with electric actuator gives proportional modulating control, as instructed by the PID Controller, with 100% authority, regardless of pressure fluctuations in the primary (district) heating supply. Unlike many other HIUs, no further control valves are required to achieve this. Anti-Scale Device To reduce the potential for scale to build up in the DHWS PHE, the flow is always diverted away from the DHWS PHE and into the HTG PHE when there is no DHWS demand. Automatic Fault Diagnostics The PID controller can identify problems within the system and displays an identifying fault code on the screen. Once the problem has been rectified the control unit automatically resets and resumes normal operation. Heating Flow Limitation This function decreases the possibility of the secondary (apartment) circuit being starved of heat when extreme demands are made on the primary (district) network. For example, in cold weather when a large heating demand is made on the network, the control unit does not allow 100% opening on start up and prevents the over demand causing disruptions. 8
Instant Hot Water Response Immediate availability of domestic hot water from the HIU is ensured at all times, as the system is programmed to charge the DWHS heat exchanger at regular intervals. This is maintained whenever there is no DHWS demand, with the PICV periodically opening to allow a small flow of hot water into the DWHS heat exchanger. The intervals between the PICV opening and the amount of hot water let through are both adjustable to suit the application or to satisfy individual requirements, but come factory set to 3.5 litres every 20 minutes Optimised Heating Control The HTG return temperatures are constantly monitored. The PID controller uses this information to maintain the optimum flow volume and temperature, which keeps the primary (district) return temperature as low as possible. DHWS Priority DHWS is the priority operation of the HIU. A flow switch detects the demand and the HIU switches to DHWS production. The HIU will still produce DHWS, even if there is a problem on the HTG side. Low Pressure Protection A low pressure switch will stop the circulating pump should the HTG system drop below 0.7bar. The HIU is fitted with a safety relief valve set at 3 bar for high pressure protection. Underfloor Heating The Range HIU is fully compatible with low temperature underfloor heating systems. The installer simply sets the required parameter on installation. Insulation The casing panels are all fully insulated, including the back-plate, to prevent overheating of the surrounding area. Prepayment Billing This can be accommodated with an accessory kit to shut down the unit when the tenant is no longer in credit. Security The metal casing can be closed, by using the optional security fixing bolts, to prevent unauthorised tampering. High DHWS Temperature Safety An integral thermostatic limiting valve, set at 60ºC, will ensure that no extreme temperatures can pass through to any outlet within the apartment. Being a mechanical device, this safety feature is maintained even if the electric supply to the HIU is cut. 9
