DocumentDocumentGreenstar Heat Interface Units An overview guide on our BESA registered Greenstar KE and E range. Installer guide Meet the next generation Heat Interface Unit (HIU) Designed with the future in mind The new Greenstar HIU is part of a market-leading range of innovative energy-saving heating and hot water solutions from Bosch Thermotechnology Ltd. The Greenstar HIU provides domestic hot water and space heating to properties that are serviced from district heating or centralised boiler plants, and is fully compatible with the Bosch Commercial and Industrial product range. Designed to meet the latest and future market requirements, the new Greenstar HIU includes a top-of-the-range appliance that offers 21 litres per minute flow rate and incorporates components such as a differential pressure reducing valve. The Greenstar HIU Innovative design User-feedback Accurate control Bosch quality Manufactured in the UK 2 Worcester Bosch HIU Call our design team: 0330 123 3004 District heating on any scale Small and large scale solutions The Greenstar HIU is perfect for both small and large scale district heating solutions. This includes flats and other multi-residential accommodation, as well as buildings that use uneconomical electric heating, or have individual gas appliances in each property. A centralised heating concept allows investors to take full advantage of a low carbon heat source or a modular/hybrid configuration with high efficiency condensing boilers. The Greenstar HIU is also compatible with Bosch Commercial and Industrial products for both new and existing multi-purpose and multi-residential buildings, as well as large estates that include commercial units. Custom solutions... from Europe's market leader in heating and hot water systems.
