Key Insights
The size of the Heat Interface Unit market was valued at USD 5.4 USD Billion in 2023 and is projected to reach USD 7.80 USD Billion by 2032, with an expected CAGR of 5.4% during the forecast period. A Heat Interface Unit (HIU) is a device used in buildings with communal heating systems to regulate heating and hot water. It transfers heat from a central source to individual apartments or spaces, ensuring efficient energy distribution. HIUs come in two main types: indirect, where heat is exchanged via a heat exchanger, and direct, where the water from the central system circulates directly. Key features include metering for energy consumption, temperature control, and safety mechanisms. HIUs are commonly used in multi-residential buildings, commercial spaces, and district heating schemes, providing a reliable and space-saving solution for decentralized heating and hot water needs.
