HIU's

With the number of UK heat networks set to grow and the continuing government investment, Altecnic have provided a cohesive guide that advises how best to optimise efficiency, and create reliable, sustainable heating systems.

The Altecnic Heat Network Design Guide aims to ensure specifiers, consultants, and contractors achieve the designed system performance post build, with a look at how maximum energy savings from HIUs can only be achieved if the system is designed, installed, and commissioned correctly.

In 2019 the UK became the first major economy to pass laws to reduce its greenhouse gas emissions to net zero by 2050. Yet in late 2021 at COP26, the UK government itself admits they are falling short of the ambitious target, to reduce emissions by 78% by 2035.

Following the October 2021 publication of both the Heat and Buildings Strategy (HABS) and Net Zero Strategy, and the GLA’s updated London Plan, the UK now has a defined route to net zero and reinforcing regulations will soon follow. But what will this look like for residents within social housing apartments, where green technology is not immediately practical to install?

Stockport Homes are upgrading the heating system to low rise apartments in the Lancashire Hill area in Stockport. This has been driven by a requirement to improve system efficiencies and reduce costs for residents, and as part of these works Essco Energy are supplying heat interface units to replace individual hot water tanks in each home.

This social housing scheme features 292 homes that are connected to a district heating network that supplies six buildings, all of which are managed by Stockport Homes. This type of system was originally installed as it operates with lower carbon emissions when compared to individual gas fired boilers in each home.

As part of Essco’s ongoing commitment to improving the efficiency of UK heat networks, their latest EDGE heat interface unit has been tested to the BESA HIU standard. Test results include a WVART of just 28°C1 and a quick domestic hot water response, meaning the EDGE-T comes out top for communal and district heating performance.

With over 15 years of HIU supply under their belts, Evinox has unveiled their latest range of ModuSat® XR ‘Smart’ Heat Interface Units, which provide M&E Contractors and Consulting Engineers with a “whole lot more” for a “whole lot less” due to the myriad of hidden extras.

Smaller, more compact dimensions; the ability to deliver high performance at low primary flow temperatures; TCP/IP communications connectivity; and new, lower output models to allow cost-effective compliance with the latest industry design standards are but a few of the ways Evinox ModuSat XR models offer more features, value and performance - but with less space requirements, lower heat network operating conditions, and less time on site to install, commission, support and maintain - than ever before.

A new urban district is being created in London's Canary Wharf, with Evinox Energy supplied heating and cooling interface units for 1330 apartments
