Heat Interface Units
Designed to meet the latest and future market requirements, our Greenstar HIU series includes a new top-of-the-range appliance that offers 21 litres per minute flow rate and incorporates components such as a differential pressure reducing valve and summer bypass.
Designed to meet the latest and future market requirements, our Greenstar Heat Interface Unit (HIU) series includes a new top-of-the-range appliance that offers 21 litres per minute flow rate and incorporates components such as a differential pressure reducing valve and summer bypass. Our KE+ and E+ HIU’s are the perfect solution for heat networks designing to CIBSE CP1 (2020) standards as both models are registered to BESA’s HIU test regime.
Direct HIU
- Low temp. Integration – Maximum performance, minimum temperature loss.
- Zero approach temp. – For more efficient low temperature heating systems.
- Smaller radiators – Preserve space in smaller properties and keep energy costs down.
- Central water treatment – Maintained in plant rooms, reducing disruption to individual homes.
