Distribution centre benefits from all-electric solution


The FUSION T packaged electric water heating system from Adveco has been installed at a new distribution centre for The Range. Located in Stowmarket, Suffolk, the 356,600m2


site has been


designed to align with the retailer’s aims of increasing sustainability and reducing lifetime carbon emissions from its properties. Part of the building specification required the provision of domestic hot water for canteen and kitchen facilities to support the expected 1650 employed across the vast site. Recognising a need for specialist


assistance, mechanical and electrical contractor WM Building Services contacted Adveco to advise on how to meet the criteria in the specification. The building could not incorporate any gas connections typically employed in larger commercial structures and there was also a need to maximise internal space for distribution functions. As a low-carbon, electric-only solution, the FUSION T met the criteria and also helped contribute towards the building securing an ‘Excellent’ BREEAM certification. The FUSION system comprises an


ARDENT electric boiler mounted to a high- pressure ATSI Stainless Steel cylinder. This provides a compact low-carbon electric water heater that can then be combined with Adveco’s FPi32 air source


heat pump and dedicated controls and metering, for further carbon reduction and operational cost savings. This FUSION T variant is claimed to be capable of cutting emissions by up to 56% compared to equivalent gas-fired alternatives. For this project, Adveco supplied 12


kW ASHP variants of FUSION packaged with 500L ATST twin-coil cylinders and ARDENT Premium 24kW electric boilers, with all necessary controls. The ASHPs feed into the lower coil of the ATST cylinder, supplying low-carbon system preheat. The electric boiler, plumbed into the upper coil supplies necessary top-up heat to achieve safe working temperatures for the commercial application, as well as meeting peak demands as and when required. The purpose-designed controls smartly manage the balance between the two heat sources, further enhancing energy efficiency levels. ◼ phamnews.co.uk/525/38


Top marks from primary school


Baxi’s Heatrae Sadia point-of-use electric water heaters are helping to contribute to the energy performance of a Passivhaus- certified primary school in Scotland. A first-year assessment of the Riverside Primary School has revealed actual energy operational performance (just 43 kWh/sqm/annum) to be significantly below the Passivhaus primary energy demand target of 60 kWh/sqm/annum, while consistently providing excellent comfort levels. The school is part of


Perth & Kinross Council’s programme of school upgrades and the appointed BakerHicks Motherwell to provide mechanical and electrical design services on the project for principal contractor Robertson Tasyside.


Council David Coulter, associate


engineer and certified Passivhaus designer at BakerHicks says: “Achieving the energy target was absolutely crucial both to achieve Passivhaus accreditation and to ensure funding for the Council. “When designing the system, the


hot water strategy was one of the main challenges as we needed to avoid large scale energy usage and heat losses. We wanted to explore using all-electric point-


of-use solutions that would only generate energy when required, for example during break or lunch times.” Such heaters can be an efficient solution


for washbasins and kitchen areas in buildings like schools. Installing a point- of-use water heater like the Multipoint that incorporates anti- legionella functionality, water pasteurisation and anti-tamper design, will ensure that water is adequately stored, cycled and distributed. “We had used Heatrae


Sadia products before and were familiar with their reputation for high-quality, robust performance,” continues David. “A key benefit of these water heaters is that the units are sized, thereby providing more flexibility to meet the required volume. This meant that we could look to design down to avoid oversizing,


where appropriate, and so ensure the most efficient operational performance.” Anne Wraith, head of commercial


product sales at Baxi, adds: “The very low heat losses of our Heatrae Sadia products were a key component in the overall project. We are extremely proud to have played a part in this groundbreaking Passivhaus primary school and at the outstanding energy results achieved.” ◼ phamnews.co.uk/525/39
