Overview

Rinnai's Hybrid System Solution has been implemented at a new luxury complex in the heart of Farringdon, London. This project features a combination of Hybrid heating and Hybrid water heating technologies to meet the diverse needs of the development.

Key Components

  • Rinnai Low-GWP 55kW Heat Pump
  • Bespoke thermal stores
  • Plate Heat Exchangers
  • 10 cascaded I2HY20 Hydrogen-ready continuous flow water heaters

These components were delivered in one complete consignment, ready for installation at the multi-million-pound development, which includes a luxury hotel, contemporary office space, and affordable housing units.

Historical Significance

The site was originally a Victorian-era schoolhouse for poor children, known as a 'Ragged School.' This heritage is respected in the new development, with many original features retained in the 150+ bedroom luxury hotel, 20,000 sq ft of office space, and nine new-build affordable residential units.

Project Details

"The site is very complex and still has many original features from the Victorian era. A full and comprehensive site survey with capital expenditure, operational expenditure, and carbon modelling was conducted. We paid special attention to the practical requirements of the site, including 150 luxury bedrooms that needed constant hot water on demand, while also meeting the site’s decarbonisation credentials."

Benefits of Hybrid Heating Systems

Hybrid water heating systems are becoming increasingly popular due to their ability to combine different energy sources for optimal efficiency. In this project, the hybrid heating system integrates a Low-GWP heat pump with hydrogen-ready water heaters, ensuring that the development meets both current and future energy standards.

  • Energy Efficiency: The hybrid heating approach allows for flexibility in energy use, reducing reliance on a single source and enhancing the overall sustainability of the building.
  • Environmental Impact: Low-GWP heat pumps use refrigerants with a lower global warming potential, making them a more environmentally friendly option compared to traditional systems.
  • Future-Proofing: The combination of a Low-GWP heat pump with hydrogen-ready water heaters ensures that the system can adapt to future energy trends, providing a long-term solution for sustainable heating.

Conclusion

The Rinnai Low-GWP 55kW Heat Pump, bespoke thermal stores, Plate Heat Exchangers, and 10 cascaded I2HY20 Hydrogen-ready continuous flow water heaters have proven to be an excellent choice for the new development in Farringdon. The hybrid heating system ensures that the development meets its hot water and heating needs efficiently and sustainably. This project highlights the importance of adopting innovative solutions like hybrid water heating and Low-GWP heat pumps to create environmentally friendly and future-proof buildings.
