The HIU Analyser is a portable tester for HIUs (Heat/Hydraulic Interface Units).
The kit allows one to rapidly test the DHW functions on an HIU to gain detailed knowledge of its performance under standard criteria.
The basis of the kit is a control valve that is inserted into the DHW supply line to control flow rate. The system operates the valve according to a recognised test regime, and monitors temperatures second by second to check performance.
As a diagnostic tool can be invaluable.
The system does not have the capabilities to control the heat network temperatures, however can highlight that they are performing as required, including measurement of differential pressures (providing there are point to insert probes).
Once the tests have been run, the system generates a detailed test report including graphs of performance, and highlighting potential problems with the system.
