heat interface units A BOILER WITHOUT A FLAME
HIU Single PHE options
heat interface units Communal Heat Networks A central boiler house will generate heat which is distributed through a network of pipe to each home or apartment in the building. Each home or apartment has its own HIU (heat interface unit), which converts heat from the network as heating and hot water for the home.
Advantages for Designers, Developers and Architects
Gas supply not required for an HIU No flues to evacuate exhaust combustion No storage cylinder required Meets low emission and efficiency targets
Advantages for the installers Easy to install, add only a programmable room thermostat Compact and lightweight Minimal installation requirements for pipe work. Simple maintenance and easy access to all components
Advantages for Landlords
Reduced service and maintenance costs Metered energy usage for fairer tenant billing Practical for combining with lower cost renewable technologies No flues to maintain for health and safety laws
Advantages for the Tenant
Shared maintenance costs Efficiently controlled heating and hot water supply Accurate billing for only the actual energy used Awareness of energy consumption promotes energy saving
