BSEE Advertorial


New Zealand­based Warm NZ has installed BoilerMag’s magnetic technology filters at the iconic QBE centre in New Zealand’s most populous city, Auckland.


Warm NZ was tasked to ensure the heating and cooling systems within the centre were up to standard and as efficient as possible as part of the major refurbishments.


As with many other projects that the company undertakes, Warm NZ installed a BoilerMag XT and ChillerMag to improve the efficiency and longevity of the heating and cooling system. Searching globally for the quality products to offer the local market, Warm NZ chose BoilerMag magnetic filters to offer the highest quality system protection to domestic and commercial properties. Sean Stephens from Warm NZ said: “Since finding BoilerMag, we instantly became fans of the filters. With their quality and ease of cleaning, we will always recommend one to be fitted to any heating system. We install them on all our domestic heating systems and have installed the

commercial ones such as those at the QBE Centre and the NZ Defence force sites we maintain as well. We will always put them forward to ensure customers know the impressive benefits, such as boiler longevity and reduction in running costs. We supply BoilerMag technology across New Zealand and would highly recommend them to all homeowners, installers and engineers.” The BoilerMag range uses high-intensity magnets to offer competitive prices and highly effective protection against black sludge within heating systems. By installing a BoilerMag magnetic filter, a wealth of benefits can be enjoyed, such as longer- lasting boilers, more effective systems and impressive annual cost savings, particularly for large commercial and industrial units.

The Grade II listed India Buildings in Liverpool has undergone a major refurbishment to deliver a BREEAM and WELL­ compliant environment, through grilles and diffusers from air movement specialist Gilberts (Blackpool).


The 350,000ft2 of commercial space is served by four-pipe heating and cooling services connected to fan coil units behind bespoke bulkheads. Consulting engineers Crookes Walker Consulting specified a combination of Gilberts’ JSL and L Series linear bar grilles in the bulkheads, GECA eggcrate grilles and GTD concealed swirl diffusers across the field area of the perforated ceilings to handle both the supply and extract of fresh air throughout the open plan commercial areas. Gilberts GX air valves ventilate the WCs. Gilberts’team executed Computation Fluid Dynamics (CFD) modelling of Crookes Walker’s design to validate optimal incoming air. In the Category A office space, the L Series of linear bar grilles provide heated air supply, with a typical 57% free ventilation area; blades can be set


at 0°, 15° or 40° deflection. ‘Fineline’ bars enable blending into the bulkheads throughout the space. GECA egg crate grilles handle extract. In the office and meeting room ceilings, the patented GTD omni-directional concealed swirl diffusers feature a frameless chassis; the radial vanes provide rapid entrainment and intermixing of high volumes of air through up to 50% free ventilation area ceiling tiles to avoid draughts or cold spots for the occupants below. The ground floor features the JSL jumbo slot linear diffusers. The air supply diffuser provides a shadow- gap appearance with high airflow, with an unbroken visual appearance. Runs up to 6m sit beside GECA egg crate grilles to provide extract.

Luceco has supplied exterior amenity lighting to the famous village of Bournville.


Over 90 Viva-City Pro street lanterns from Kingfisher Lighting, part of the Luceco PLC Group, were chosen to illuminate the streets and canal area of Bournville, some with the columns boasting the purple livery of the famous “glass and a half” chocolate bar that became the most popular chocolate consumed in Britain. The story of Bournville commenced in 1878 when the manufacturer set up its manufacturing process in a meadow with a trout stream called the Bourn…. and the rest is history.


Viva-City Pro is a modular, slimline, performance LED street lantern offering a choice of optics. Manufactured from high pressure die-cast aluminium, the luminaire is IP66 and IK10 rated and has an efficacy of up to 141 Llm/W and can produce up to 24,000 luminaire lumens at 4000K with a CRI >70. The range offers 15W – 180W


power options with 2,062–24,741 luminaire lumens respectively and an operational working life of 100,000 hours. Viva-City Pro is at home in many amenity lighting applications such as urban environments and civic areas, car parks, streets and highways and offers a choice of optics with asymmetrical distribution. The optics include street and area options, as well as a 50° Flood Optic, 70° Street Optic and 70° Area Optic as used at Bournville, ensuring the light distribution pushed the illumination outward generating a rounded pattern with little light falling behind the luminaire mounting position. Mounting options include both 60mm post-top and side- entry and accessories include photocell and dimming options.


www.luceco.com Ecodan renewable heating is just what the doctor ordered


Mitsubishi Electric has provided a medical practice in South London with three commercial Ecodan air source heat pumps (ASHP) to deliver renewable heating and year­round comfort.


The owners of Paxton Green Group Practice needed a heating solution that would future-proof the building by reducing both heating bills and carbon emissions, to replace the existing gas boilers. Ecodan CAHV monobloc ASHPs from Mitsubishi Electric were chosen due to their ability to lower running costs and carbon emissions. Patients and staff can now benefit from cost-effective, renewable heating while also enjoying modern levels of comfort.


The heat pumps were installed to deliver 116kW of heat to the building, replacing the two commercial gas boilers. The CAHV models operate in a cascade system, meaning they are able to continually match the heating but only consume the power needed to keep the practice comfortable, whatever the weather. Andy Booth, project manager for Opus Air Conditioning, which installed the system said: “One


of the things that amazed me was how quickly the CAHV units heated the water in the tank. We picked up water temperatures of 70 degrees in less than 30 minutes.”


Owing to the practice being a vaccination centre for its local community, the heat pumps had to be installed and the old systems removed in close partnership with the practice and its opening times. “The team had to be completely flexible so that we could get in around the working hours of the vaccination centre,” added Mr Booth. Heat pumps are low maintenance and able to produce an average of three kilowatts of heating for every kilowatt of electricity consumed. The practice can now provide a high-quality healthcare service for patients whilst also delivering high levels of comfort.
