BSRIA has just released a new series of reports on the market Heat Interface Units (HIUs). 

HIUs first appeared on the European market around 20 years ago. It took quite a few years for these products to overcome initial challenges, but the market is set on a dynamic rise. Growth comes from multi-dwelling projects mostly in new construction and the gradual progression of district and communal heating. This overview focuses on the state of the heat interface units’ market, looking at the current HIU market size, competitive landscape, and 5-year forecast.

Reports are updated annually, based on interviews with suppliers and major stakeholders in the heating industry. BSRIA also use external data from secondary sources for deeper analysis.
