OMMERCIAL HEATING | PRODUCT NEWS Fuel cell mCHP boiler may rival heat pumps Product can cut CO2 emissions by up to 30%, says manufacturer Viessmann will launch its new fuel cell micro combined heat and power (mCHP) boiler at this years Installer 2019 and the All-Energy Show in May. Vitovalor PT2 will have an Energyrelated Product (ErP) rating of A+++, which corresponds to an annual seasonal efficiency of up to 192%, making it an alternative to heat pump systems, the manufacturer has said. The unit has a 40,000kWh heat load demand, and generates electricity as well as heat. It can generate enough electricity to cover the basic demands of an average household, save up to 40% of household energy consumption and reduce CO2 emissions by up to 30%, the manufacturer has claimed. With fullyintegrated hydraulics and a footprint of 0.72m2, the product comes in pre-assembled modules, and includes a 220L integrated stainless steel hot water cylinder, making it more suitable for larger properties. The unit is available in four heating outputs 11, 19, 25 and 30kW and is equipped with a new control platform, which offers faster communications between the end-user, installer and manufacturer. The unit will be launched on 7-9 May at the Ricoh Arena Coventry, and the AllEnergy Show in Glasgow on 15-16 May at SEC Glasgow. Compressor delivers 15% efficiency A heat pump, featuring a new compressor, delivers a 15% increase in efficiency, Daikin has claimed. As well as variable refrigerant temperature and continuous heating during defrost, Daikin says the VRV IV+ system has a redesigned compressor to ensure good performance at part loads its main operation mode throughout the year. To avoid refrigerant leaks that can occur during low-load operation from the high-pressure side to the low-pressure side in the compression chamber, resulting in loss of efficiency, the compressor has a back-pressure control port that sends a small amount of high-pressure refrigerant from the compression chamber to the back of the scroll. This separation of lower- and higher-pressure sides within the compression chamber boosts seasonal efficiency, resulting in a 15% increase in efficiency, according to the manufacturer. )\PS[MVY[OLM\[\YL 9LHK`UV^ Kenwood Hall hotel upgrade for Vokra Six outdated boilers serving rooms, the kitchen, restaurant and public areas at the recently rebranded Mercure Sheffield Kenwood Hall Hotel and Spa (formerly Best Western Plus) have been replaced with three units by Vokra, through its parent company Riello Group. The 90kW boilers are installed in a linear cascade configuration, and each boiler can be operateed either as a primary or secondary in the cascade, ensuring constant operation even while being serviced. The units have an optimised stainless steel heat exchanger, with single- or double-coil patented sections and premix burners for high turndown ratio and low emissions, according to the manufacturer. As well as working with a confined plant room space, specific requirements at Kenwood Hall meant an extended external flue was required to clear the roof. Heat for Good team delivers rugby club makeover The Heat for Good collective, including 11 heating engineers from around the UK, has installed a free heating system to the Clayton Rugby League Club in Bradford, West Yorkshire. Eleven installers gave up their time to fit a combi boiler, with radiators, and a low-loss header, in a community kindness initiative sponsored by Viessmann. Darren McMahon, marketing director at the firm, said: The old heating system was in dire need of replacement; its something that clubs like Clayton struggle to fund without some help. 9 3LHKPUNI\YULY[LJOUVSVN`MVYV]LY `LHYZ 9 4LL[PUN[OLJSPTH[LJOHSSLUNLZVM[VKH` HUK[VTVYYV^ 9 4H_PTPZPUN,MJPLUJ`HUK4PUPTPZPUN ,TPZZPVUZ 9 ;OL5VJOVPJLMVY:WLJPLYZ 9 -\SSWYVK\J[Z\WWVY[MYVTJVUJLW[[V JVTWSL[PVUHUKIL`VUK 9 (UL_[LUZP]LYHUNL[VJV]LYR> [VR> =PZP[YPLSSVI\YULYZJV\R [VUKV\[TVYLVYWOVUL VU COMMERCIAL & INDUSTRIAL 6 May 2019 www.cibsejournal.com CIBSE May19 pp06-07 News Supp.indd 6 26/04/2019 15:22
