EDGE T HIU Powered by ESBE

EDGE Heat Interface Unit (HIU) Range

Our HIUs feature first-class components, including the market-leading valve from ESBE and intelligent electronic flow and temperature control technology.

We focus on quality design and manufacturing.


Providing hydronic separation using heat exchangers can benefit many systems and applications, giving protection, control and system optimisation.

From oversized bespoke heat interface units to ambient sub-stations or district heating sub-stations, we cover all bases.

Heat Network System Design

We can work along-side you to provide design support and guidance for heat network systems, backed up by PI insurance cover.

Our technical engineers have extensive knowledge and expertise and can project manage the design from start to finish if required.

Water Treatment

We partner with IWTM-UK Ltd who lead the way in corrosion protection for water recirculation systems.

IWTM provide a chemical-free solution that uses a sacrificial anode to extract oxygen, acid, and aggressive salts from the water.

It’s the perfect choice for protecting both new and existing systems.
