HIU Repairs

Where an HIU has developed a fault, our engineers can attend to diagnose the issue and advise on the most appropriate remedial action. This may include replacement of faulty valves, actuators, sensors, meters, strainers or other serviceable components. Where a unit is beyond economical repair or no longer suitable for the system requirements, we can recommend and support replacement options.

The Benefits of Professional
HIU Aftercare

Regular HIU servicing is essential for maintaining reliable heating and hot water performance within communal and district heating systems. A well-maintained Heat Interface Unit (HIU) helps ensure residents receive consistent heating and hot water while supporting the overall efficiency of the heat network.

At Link365, our professional team provides comprehensive HIU servicing and aftercare solutions for residential and commercial developments across the UK. Our experienced engineers carry out detailed inspections of the HIU, controls, valves, heat exchangers, metering equipment, and associated connections to ensure all components are operating safely and efficiently.

Routine servicing offers a range of benefits, including improved energy efficiency, reduced heat loss, accurate metering, and enhanced system reliability. By identifying early signs of wear, leaks, poor flow rates, or control issues, planned maintenance can help prevent costly breakdowns and minimise disruption to residents.
