Innovative HIUs

By constantly innovating through applying cutting edge technology, we are leading the way in heat interface unit (HIU) development. This ensures our HIUs deliver smart insights, high-quality heat with less carbon and cost for operators and residents. ICON is the first 5G NB-IOT enabled, fully connected HIU. ICON provides data to its proprietary web-based portal, allowing network stakeholders to analyse unit performance and make remote adjustments or conduct pro-active maintenance - improving efficiency, cutting carbon and costs. Compliant with CIBSE CP1, and with WRAS and BESA approval, ICON represents a paradigm shift in HIU technology.
