Leading heating technology manufacturer, Grant, has been recognised for Outstanding Innovation for the new Grant Aerona R290 air source heat pump at the Plumbing & Heating Awards 2024.

Designed in Ireland, specifically for the Irish and UK climate, the Grant Aerona R290 heat pump is already proving itself to be in another league in terms of innovation and efficiency. A significant addition to the Grant product portfolio, this new heat pump reinforces Grant’s commitment to delivering innovative and sustainable home heating solutions.
Throughout the research and development phase, Grant heavily invested in design and testing of the new heat pump range to ensure the technology is best suited for year-round climate conditions in Ireland and the UK. This was recognised by the judges at the awards who described the Aerona R290 as “redefining heating innovation and sustainability” and said that it “sets a new benchmark for low-carbon heating.”
Aesthetically pleasing, the Grant Aerona R290 heat pump uses environmentally friendly R290 refrigerant, which has and has an incredibly low Global Warming Potential of 3 compared to other refrigerants used in heat pumps, signaling an important advancement in sustainable home heating.
Cleverly designed to suit many types of homes, the A+++ rated Grant Aerona R290 range provides exceptional performance with ultra-low noise levels, which are recognised by the internationally acclaimed Quiet Mark. Units in the range can also be remotely managed using the new Grant Aerona Smart Controller, which provides peace of mind for both the user and the installer.

Commenting on the award win, Barry Gorman, National Renewables Sales Manager at Grant, who accepted the award on behalf of the company, stated: “We are thrilled to receive this recognition for the Grant Aerona R290 air source heat pump range. The Grant Aerona R290 air source heat pump delivers exceptional performance and uses the highly energy efficient R290 refrigerant to provide an even more environmentally friendly, low carbon heating solution for homeowners throughout the island of Ireland.” Learn more about the Grant Aerona R90 here“
What is R290 refrigerant?
R290, a natural hydrocarbon known as Propane, is widely used in air conditioning and refrigeration and is gaining popularity in low-carbon air source heat pumps. Non-toxic, odourless, and energy-efficient, R290 boasts excellent thermodynamic properties, efficiently transferring heat from air to heating systems.
In an air source heat pump, R290 follows a cycle of evaporating into gas to absorb heat from air, compressing to increase heat, and condensing back into liquid to release heat into the water system. This process is both sustainable and efficient, making R290 a superior refrigerant choice.
As the demand for renewable heating solutions continues to grow, Grant’s innovative heating solutions offer a forward-thinking approach that aligns with the future of homebuilding. Grant’s legacy of innovation and excellence provides customers with a trusted partner for creating homes that are built for a sustainable future.
