Ariston has supplied the Climate Innovation District in Leeds (CITU) with the first of many air source heat pump water heaters for a range of new build properties designed and built in line with key Passivhaus principles.
The Climate Innovation District in Leeds is a transformational project as part of a new neighbourhood in the Hunslet Riverside area of South Bank. The development comprises 955 family homes and apartments, alongside a multigenerational building incorporating a primary school, a care home and a nursery, offices, cafes, restaurants, and outdoor sports facilities.
Being designed and built to key Passivhaus principles means these homes are well insulated and airtight, reducing the heating load significantly compared to traditional buildings. All the properties are also linked up to a site-wide photovoltaic (PV) installation, enabling them all to share in the generation of electricity on site and further reduce reliance on the grid.
Smart heat pump technology for modern homes
Across the development, Ariston’s innovative Nuos Plus Wi-Fi water heater features in all of the larger residential properties, offering highly efficient, reliable hot water. The air source heat pump (ASHP) in the Nuos Plus Wi-Fi is used to heat the integrated hot water cylinder for the property, meaning hot water for baths and showers is heated using the air outside, and boosted by electricity as required.
This works alongside the Mechanical Ventilation Heat Recovery (MVHR) unit that CITU has installed in properties, which keeps the internal air fresh but warm, in line with Passivhaus design principles.
Rachel Luffman, Head of Design for Climate Innovation District, commented: “The cylinder in the Nuos Plus Wi-Fi air source heat pump is large enough to support a family home, and the ventilation needs for it can coordinate with those needed for the mechanical ventilation heat recovery system. We have installed these in several homes now and they are fit for purpose, so we will continue to install them in the Climate Innovation District.”
Why Ariston ASHP water heaters?
One of the key benefits of using Ariston’s Nuos Plus Wi-Fi is the substantial reduction in carbon emissions associated with heat pump water heating technology. With the ASHP water heater operating on renewable energy, CITU’s decision to install Ariston solutions aligns with the commitment from Leeds to combat climate change and create sustainable living environments, showcasing the viability of this technology in a real-world, sustainable living context.
Ariston’s ASHP water heaters are some of the most efficient in the market, thanks to its longstanding heritage and technical expertise. Offering a highly efficient COP of up to 3.14, the Nuos Plus Wi-Fi is A+ energy rated and offers up to 80% more energy savings compared to traditional electric storage water heaters and can reach water temperatures of up to 62ºc.
Ariston has recently expanded its range of water heaters further, with the launch of the Nuos Plus S2 Wi-Fi. The new R290 model offers an ultra-low GWP of 3, with an A+ energy rating and a COP of up to 3.51.
Both the Nuos Plus S2 Wi-Fi and Nuos Plus Wi-Fi have low operating noise levels of 48 dBA and 51 dB respectively, meaning minimal disruption for homeowners and occupants.
