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.
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.”
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.
