It is essential to ensure your heat network operates to acceptable standards before handing over to commissioning services and site acceptance testing.
For maximum energy savings, Heating Interface Units (HIUs) must be correctly selected and sized, plus a system must be designed, installed, and commissioned appropriately.
HIUs require a deep understanding of complex systems, as well as dedication to tenant and occupier satisfaction. Our Heat Interface Unit repair and installation team is experienced in working with a variety of different HIU brands.

WilSon Energy offers a full range of installation and commissioning services for HIUs, heat metering and billing systems for our own as well as 3rd party technologies. Our services cover both mechanical and electrical projects. By choosing WilSon Energy, you can be confident that the equipment will operate at optimum performance and in accordance with the manufacturers recommendations.
