Heat Interface Units R&D

Performance testing of HIU

When it comes to R&D tests, flexibility is a common requirement. For this reason R&D test benches ensure:

  • free tests
  • automatic functions (ramps and PID controls)
  • measurements and trends displayed on a graph
  • log functions
  • test sequence management tool

List of common tests:


    • Heat Exchanger Power Test – DHW mode
    • First response time test – DHW mode. Start from cold heat exchanger
    • First response time test – DHW mode. Start from hot heat exchanger
    • DHW response time and temperature stability test at variable DHW flow in steps
    • DHW activation-deactivation test
    • DHW response to external disturbances
    • KVS test of CH, DHW and DHW recirculation circuits
    • Temperature regulation test
    • Response to opening and closing of zones

    All test data are saved into Excel files
