Cooling and Heating Interface Unit
A heat interface unit that lets one radiant terminal provide winter heating and summer cooling. Dew-point control on the water side helps prevent condensation.
HIU EQUIPMENT & OEM COMPONENTS
Heat interface units and the hydronic parts behind them.
CHUNHUI supplies complete HIU equipment, and the hydronic blocks, valves, pumps and sensors that heating-equipment manufacturers integrate into their own units.
- Complete HIU units
- OEM hydronic components
- Built for heating-equipment manufacturers

See what we supply
Complete HIUs, or the parts that go into them.
Work with CHUNHUI as an HIU equipment supplier or as an OEM partner for hydronic components. Both paths use the same water-side manufacturing base as our work on boilers, heat pumps and heat interface units.

Cooling and heating interface units at the dwelling — the interface between a heat network or plant room and the apartment circuits.
HIU equipment
Complete heat interface units and fresh water stations for dwelling-level heating, cooling and domestic hot water.
Fresh Water Station
Integrates multiple heat sources to deliver hygienic, constant-temperature domestic hot water — as a complete station or as DHW-side components for your HIU.
OEM hydronic components for HIU and heating programmes.
Supply the parts inside the HIU — hydronic blocks, PICV, safety valves, pumps, motorised valves, sensors and actuators — as catalogue items or to your drawing.
