Grant continues to support low-carbon retrofits across Ireland

Ireland’s retrofit challenge is increasingly defined by the ability to deploy solutions across a wide range of property types and retrofit scenarios.

With ambitious national decarbonisation targets in place, success depends on heating technologies capable of consistent performance across diverse applications, while operating reliably in Ireland’s climate and integrating well with existing housing stock.

A large proportion of Irish homes were built before modern energy standards, making system design, installer expertise and proven technology critical factors in achieving real-world emissions reductions.

Leading Irish heating technology manufacturer Grant continues to support low carbon retrofits by developing sustainable heating solutions designed specifically for the Irish and UK climate. Through ongoing investment in research, product development and professional training, Grant is supporting homeowners, architects, engineers, installers and contractors in the delivery of retrofit solutions that improve comfort, reduce emissions, and future-proof homes.

At the forefront of this effort is Grant’s award-winning Aerona R290 air-to-water heat pump. Designed in Ireland specifically for local climate conditions, the Aerona R290 provides a next-generation solution capable of supporting a wide range of retrofit applications, from individual homes to larger housing developments.

The Aerona R290 has been recognised for its outstanding innovation at industry awards where it was described as ‘redefining heating innovation and sustainability and setting a new benchmark for low carbon heating solutions’. The Aerona R290 was also named ‘Heat Pump of the Year 2025’ at the Plumbing and Heating Awards.

From a technical perspective, the Aerona R290 delivers reliable operation in challenging environments, achieving A+++ ErP ratings, with SCOPs up to 4.88. The system is capable of 75°C flow temperatures, though correct system design ensures lower, more efficient temperatures are used where appropriate. The range includes five models with outputs from 4kW to 16kW, providing flexibility across a variety of property types. Integrated remote monitoring and management capabilities with the Aerona Smart Controller also support ongoing optimisation and diagnostic support as needed.

Crucially for retrofit projects, the Aerona R290 uses natural refrigerant R290, which has a Global Warming Potential of just three. Combined with ultra-low noise performance recognised by Quiet Mark, the system aligns with national and European sustainability objectives while remaining suited to established residential areas.

Beyond the technology itself, Grant continues to invest in the skills and knowledge required to support successful retrofit delivery. Through a combination of onsite training at the purpose-built Grant Training Centre and online learning via the Grant eLearning Academy, installers and industry professionals can access up-to-date courses on products including the Aerona R290 heat pump. This focus on education supports consistent installation quality and helps ensure that retrofit systems perform as intended over their operational lifetime.
