New hybrid heat pump system solves luxury complex’s needs in London City.

Rinnai Low-GWP 50kW Heat Pump, bespoke thermal stores, Plate Heat Exchangers and ten cascaded I2HY20 Hydrogen-ready continuous flow water heaters specified at new development in the heart of Farringdon district of London.
A state-of-the-art project in the heart of the Farringdon district in London is set to revolutionise the way we look at sustainable heating and hot water systems. Rinnai’s Hybrid water heating H2 array of Low-GWP 50kW heat pumps, along with bespoke thermal water stores, have been combined with ten cascaded Hydrogen blends ready continuous flow water heaters at this new development. These cutting-edge systems were delivered in one complete consignment, ready for installation at a multi-million-pound complex comprising a luxury hotel, contemporary office space, and affordable housing units.
The site’s rich history as a Victorian-era ‘Ragged School’ for underprivileged children adds a touch of heritage to the modern redevelopment project. The renovated site will retain many original features in the 150+ bedroom luxury hotel, opulent office space, and affordable residential units, paying homage to its historical significance.
Darren Woodward, representing Rinnai, highlighted the complexity of the site and the importance of a comprehensive design to meet the demands for constant hot water supply while adhering to decarbonisation requirements. The hybrid system, incorporating a heat pump, plate heat exchangers, bespoke thermal stores, and Hydrogen-ready water heaters, provides an efficient, economic, and sustainable solution for the development.
