PRODUCTS | SERVICES Products of the month Rinnai supplies hot water and heating system to luxury London development Hybrid system provides practical and economic technical solution at complex in the city R innai has delivered its Hybrid H2 system to a new luxury complex in the heart of the Farringdon district of London. The heating and hot-water solution combines a low global warming potential (GWP) 55kW heat pump, bespoke thermal stores, plate heat exchangers, and 10 cascaded I2HY20 hydrogenready continuous flow water heaters. The comprehensive system was supplied in one consignment, ready for installation at the multimillion-pound development. The luxury complex, which encompasses a new hotel, contemporary office space and affordable housing units, required a versatile and efficient design to meet the diverse demands of the site. The multipurpose use of the site meant only a fit-for-purpose design would satisfy the practicalities and nuances of space, and ensure demand and energy usage are met 24/7. Rinnais solution was tailored to ensure continuous hot-water supply, while addressing the sites decarbonisation goals. The system incorporates a hybrid approach, with a heat pump, plate heat exchangers, thermal stores, and hydrogen-ready water heaters. The historical significance of the site adds to the projects uniqueness. The development pays homage to its heritage as a Victorian-era schoolhouse for impoverished children, known as a ragged school. Retaining many original features, the building provides a blend of modern amenities with a nod to the past. The site is very complex and still retains many original features from the Victorian era. We conducted a thorough site survey, considering capital and operational expenditure, as well as carbon modelling, Darren Woodward, spokesperson for Rinnai, explained. Our hybrid system was delivered as a complete package. We believe this type of solution represents the future for larger retrofit projects in London and other cities, combining practicality, cost-effectiveness, and reduced carbon footprint without compromising performance.
