Intatec HIU Servicing
Intatec units are common in newer London developments. Like any HIU, they benefit from annual servicing to maintain performance and catch faults before they cause a breakdown.
Flow control valve checks, heat exchanger inspection, control module diagnostics, and flow and return temperature verification against design targets.
