Hybrid systems integrate an eclectic heater within the HIU, providing a combination of mechanical and electrical on-demand heating. This is ideal for use with heat pumps and solar systems, which typically have a lower primary temperature, making water slower to heat up. The built-in electric heater adds the extra heat to cut out the delay and assure the right temperature all day throughout the building.

Single Plate HIUs are used to heat domestic hot water (DHW) only. Units with control and metering of space heating are provided where the primary hot water supply is circulated directly through radiators in each apartment, rather than having a separate heating circuit. DHW-only units are used to provide hot water typically in institutional or commercial settings.
