PRODUCT PROFILES | HEATING AND VENTILATION PRODUCTS Sime launches Revolution Sime has launched its Murelle Revolution 30, the first completely integrated boiler and heat pump in a single cased product. Using an ErP A++ 30 kW Murelle boiler and completely sealed 4kW output heat pump, Sime is said to be targeting its Murelle Revolution 30 at new build, social housing and the retrofit renewables markets. Available from the beginning of April 2018, the Murelle Revolution 30 is a single compact unit and can reportedly be installed by any registered Gas Safe installer in a single installation process, without requiring an additional F-gasregistered installer to be present. According to the company, the unique Murelle Revolution 30 should be installed inside and hung on the wall like a conventional boiler. Possessing two inlets, in addition to the flue outlet, the Revolution is said to provide heat and hot water, achieving an average seasonal heating performance of 134%, granting A++ energyefficiency, according to the ErP Ecodesign Regulation. Massimo Bizzotto, Sime general manager, said: “Sime is renowned for its investment in technology and our Murelle Revolution 30 is a global first, and one of the most technically advanced products on the UK market. We have already seen the Murelle Revolution 30 successfully piloted in Italy and in Spain and we are in discussions with leading UK construction and heating clients about how the Murelle Revolution 30 will fit with their own renewable projects. www.sime.co.uk Johnson & Starley’s hi-spec and economaire heaters hand over to the new warm air heating range In 2013 Johnson & Starley launched its successful range of WarmCair condensing warm air heaters, along with its QuanTec range of boilers that can be connected to its warm air heater emitter range, Aquair. These units are said to be highly efficient, giving customers ‘significant savings’ on running costs and will meet all future eco-design regulation requirements. The increasingly popular boiler/warm air heat emitter, the QuanTec and Aquair package, is said to be a ‘cost effective’ and efficient way of replacing an existing warm air heating system with a wet system boiler and a heat emitter which will reportedly enable you to still utilise the existing warm air ducting via the Aquair. The Aquair takes water from the boiler and passes it through a heat exchanger which has a fan blowing across it. This forces the warm air out into the original ducting. Because all the gas work is contained within the boiler, Johnson & Starley says the gas engineer does not need to be warm air qualified to install it. www.johnsonandstarley.co.uk Big Foot Systems rises to the challenge Big Foot Systems has supplied HD beams, custom steels and custom HD frames as part of a £40 million redevelopment of a shopping centre. Originally constructed in the late 1960s, the centre required a refurbishment to be able to compete with other local retail complexes, including new heating, ventilation and air conditioning plant. With retail space at a premium, new locations were needed for the chiller plant with the rooftop an obvious choice. Meanwhile, the existing air handling units (AHU) also needed to be replaced and relocated. The original AHUs were located on plinths that were constructed when the shopping centre was initially built, but since the new AHUs were larger, the existing plinths could not be utilised without structural alteration and so an alternative solution needed to be found. With the new rooftop location BUILDING PRODUCTS | MARCH for plant posing a few issues, Big Foot Technical reportedly worked closely with the contractors to design a suitable solution. The 1960s roof had not been designed to support plant and so the permissive loads on the roof were limited to a Uniform Distributed Load (UDL) of less than 4kN/m². Another challenge was that the roof was due to be re-roofed at a future date, therefore any frame supplied had to provide adequate stability and clearance for re-roofing. A custom design was therefore required for the project with Big Foot’s engineers, using software including 3D CAD and ANSYS FEA, to create a solution that would support the chillers and AHUs, provide the required clearance and could maintain an imposed UDL of less than 4kN/m2. Sam Birch, from Big Foot Systems, said: “This was a complex project due to the weak roof. Initially it was thought that the plant loads would need to be taken back to the main structural beams but, working with the contractors, Big Foot Technical was able to design a solution that could be supported by the roof whilst being secure, below the UDL and at a lower cost than initial options.” HD custom frames are projectspecific, non-penetrative support frames for large, heavy, irregular shaped or unevenly loaded plant. Big Foot Systems can design and manufacture complete one-off solutions. HD beams are a non-penetrative support solution for chillers, AHUs, packaged plant, generators, pipes and steels. They are described as a robust but flexible solution where space may be limited, or there is a requirement to position directly over existing structural roof beams, and weight is evenly distributed across the specified quantity of HD beams. They are also height adjustable to maintain a level system on roof falls up to 5° www.bigfootsupport.com
