Evinox Energy has launched a new CIBSE accredited CPD seminar following the introduction of the first UK test standard for Heat Interface Units from BESA (British Engineering Services Association).

This new standard is regarded as an important step towards improving the overall performance of British district heating schemes and its key objective is to enable the performance of different HIUs to be evaluated within the context of typical UK operating conditions. Thereby enabling heat network developers to consider the performance of specific HIUs against design requirements.

Until now, it has been a common misconception that heat interface units are “one size fits all”; results from the BESA tests show that this certainly isn’t the case for today’s modern systems – the network design and HIU specification must be closely matched to ensure optimum performance and the HIU must deliver the widest delta T and lowest return temperatures possible in all operational modes.

The Evinox seminar explores all aspects of the test regime and discusses how for the first time, designers and specifiers will be able to see the impact of a specific HIU on their network. Entitled “Understanding the BESA Test Standard for HIUs (VWARTS and All)”, the seminar is accredited by The Chartered Institution of Building Services Engineers (CIBSE) and provides credits towards consulting engineers’ Continuing Professional Development (CPD).

This 60-minute seminar is ideal for M&E consultants or housing providers interested in finding out more about the latest standard for communal & district heating systems and can be held at client’s premises or at the Evinox Energy offices in Chessington.

Contact Evinox today to arrange a seminar on 01372 722277 or complete the contact form on the website.

Evinox are very proud to announce that the ModuSat® XR Heat Interface Unit has been tested to the BESA (British Engineering Services Association) UK Standard for HIUs, achieving impressive results all round.

Launched in late 2016, the BESA UK Standard for Heat Interface Units was introduced to help designers and specifiers evaluate the performance of a particular HIU on their network. This new standard aims to provide HIU benchmarking, similar in many ways to the well-known SEDBUK scheme for domestic boilers.

Currently, only a handful of manufacturers have published results for the HIU test regime, with Evinox being one of the first to undertake the testing process.

With an overall VWART of just 33.4℃, impressively low domestic hot water return temperatures and the ability to deliver flexible Keep Warm operation, the BESA test results provide a clear, independently verified confirmation that the Evinox ModuSat® XR range delivers outstanding heating and hot water performance for modern heat networks.

Mike Shaw, Commercial Director at Evinox Energy commented “We believe independent testing is a vital step forward for the Communal & District heating industry, and as one of the UKs most established HIU manufacturers, we were determined to be involved from the early stages. Our latest ModuSat® XR and XR-ECO models have been developed very much with the new standard in mind and we’re confident that this regime from BESA will lead to more efficient heat networks being designed and delivered”.

The BESA standard is currently optional for HIU manufacturers, however, Evinox believes this will be a mandatory requirement in the near future, and asks designers and specifiers to start insisting on the use of BESA tested units for their heat network projects going forward.

The full report and test results can be found by visiting, or contact Evinox to book a CIBSE accredited CPD Seminar on 01372 722277.

Evinox has extended its best-selling range of ModuSat® Heat Interface Units with the introduction of the new ModuSat® XR and ModuSat® XR- ECO Twin Plate models. Providing both indirect space heating and domestic hot water, ModuSat® XR units are ideal for use in modern, efficient district and communal heat networks. All units deliver fast, dynamic domestic hot water response, and the ModuSat® XR-ECO models also provide ultra-low DHW return temperatures to the primary heat network.

With extensive experience in the design and application of HIU’s across thousands of UK-wide installations, Evinox has made significant advances in the performance of its latest range, aiming to help improve the overall efficiency of heat networks, whilst retaining high levels of user satisfaction and comfort levels.

ModuSat® XR – even faster, more efficient domestic hot water performance

An overriding requirement for many consulting engineers involved in the design and specification of heat networks, is to ensure abundant and responsive supply of domestic hot water. This goes hand-in-hand with residents expecting consistent and safe hot water at the tap. ModuSat® XR HIU’s deliver fast hot water without reducing the efficiency of the heat network.

“There is strong evidence that speed of hot water delivery is a key requirement for residents living in homes operating on communal and district heating schemes” comments Emma Alexander, Evinox Energy Marketing Manager. “The ability to be able to deliver abundant hot water quickly, while at the same time ensuring the efficiency of the heat network is not compromised, is a key challenge for heat network designers and HIU manufacturers, so the improved performance of the new ModuSat® XR range is an important step forward in this area.”

Evinox ModuSat® XR-ECO; how low can you go?

It’s clear that lowering system temperatures is a critical factor in the efficient operation of UK heat networks. Reducing the network primary flow & return temperatures enables heat generation plant to operate more efficiently; lower grade, low carbon heat sources to play a more predominant role in the energy mix; and network heat losses to be dramatically reduced.

ModuSat® XR-ECO units have been designed precisely with this in mind, incorporating ultra-high efficiency domestic hot water plate heat exchangers with improved volumetrics that encourage turbulent flow and optimal heat transfer.

These latest improvements mean designers are given the opportunity to focus on the energy efficiency performance of HIU’s and the wider heat network, with the confidence that units will continue to deliver impressive full load hot water capacity and flow rates.

A New Test Standard for Heat Interface Units from BESA

The ModuSat® XR has been tested under a new UK test standard, intended to help heat network designers to evaluate individual HIU performance on their network under typical UK conditions. The new scheme, operated by the Building Engineering Services Association (BESA), will provide HIU benchmarking, similar in many ways to the SEDBUK scheme for domestic boilers.

Evinox believes independent testing is an important step for the UK HIU industry, so the latest ModuSat® XR and XR-ECO models have been developed very much with these new standards in mind. Evinox is confident that this new standard will lead to HIU systems and heat networks being designed with efficiency as much as maximum hot water capacity being the key consideration.

The Ladbroke Grove development from Taylor Wimpey Central London, is part of the regeneration of Grand Union Centre, and includes both luxury apartments and homes for first-time buyers, close to Kensington and Chelsea. This mixed use scheme combines living and working, with office accommodation and retail units available alongside a high-quality development of apartments set around a private courtyard in W10.

Evinox Energy are delighted to be working with P R Morson on this outstanding development, supplying heat interface units and metering & billing services.

Design and sustainability

To reduce the environmental impact of the development, the apartments are all connected to a communal heating system, which supplies residents with thermal energy for heating and production of domestic hot water. System water is heated in a central plant room, distributed via pipework around the building and energy is transferred to residents via a ModuSat HIU.

The ModuSat HIU’s at The Ladbroke Grove include both an energy meter for heating and hot water, and an electricity meter, meaning residents will be billed for both utilities by Evinox Energy.

In Built Pre-Payment Facility

Evinox ModuSat HIU’s are supplied pre-payment or credit account ready, meaning there is no requirement for additional controls, sensors or hardware providing flexible metering options.

With most modern housing schemes being mixed use, the ability to operate a part credit billing and part pre-payment system on the same scheme is extremely desirable, and providing a future proof solution is a key advantage of the Evinox system, as it can be adapted to different tenant occupations. The ability to make changes remotely provides the ultimate in simplicity and flexibility at The Ladbroke Grove.

By combining smart HIU’s with excellent after-sales, end user support and flexible metering and billing services, the building owner has a hassle-free, sustainable development and residents enjoy a fantastic place to live.
