HIUs are typically installed in multi-family apartment buildings in which a central heating plant provides heating and in some cases hot domestic water to all units.
Our state-of-the-art HIU controls allow for multiple zones control and remote metering/billing on an individual appartment level. This increases transparency and efficiency of energy usage.
For maximal efficiency we combine HIU with heat recovery ventilation (HRV). As a result, heating costs can be significantly lowered.
