The Importance of HIU servicing in district heating

Heat Interface Units (HIUs) are essential components of district heating systems, which provide heating and hot water to homes and businesses. These units work by transferring heat from a central source to individual units, and they need to be properly maintained in order to operate efficiently and reliably.

How often should HIUs be serviced and what to expect?

The frequency of HIU servicing should be every 6-12 months or following manufacturers guidelines.

During routine servicing, our technicians will inspect your HIUs for signs of wear and tear, correct operation and ensure it is operating correctly.

If any problems are found, our service team will discuss the findings with you and recommend a course of action. We offer a variety of repair and maintenance services, so we can always find a solution that meets your needs and budget.

  • Ask about the frequency of servicing: The frequency of servicing will vary depending on the specific HIU. Ask our service team for recommendations on how often your units should be serviced.

condition of the units and make sure that they are being properly maintained.
