The increasing popularity of the new Grant Aerona R290 air-to water air source heat pump is no surprise due to its ability to deliver outstanding performance in the Irish climate, its high efficiency and simple installation. With an ErP rating of A+++, the award-winning Aerona R290 has become a go-to choice for new build and deep retrofit projects who are seeking reliability, streamlined installation, and compliance with evolving building regulations.
With five models from 4kW to 16kW, the Aerona R290 can be specified for anything from compact starter homes to larger family dwellings, making it suitable for both individual builds and multi-unit developments.
The unit also comes with key components already fitted, including a high-efficiency PWM circulating pump and a DC twin rotary compressor, which means fewer parts to source and quicker installations on site. Its compact design and quiet operation also helping to simplify planning, making it easier to integrate into residential developments without disruption and with less on-site work, this translates into shorter timelines, fewer delays, and smoother handovers.
Each heat pump is supplied with the Grant Aerona Smart Controller, which provides an intuitive, easy-to-use interface that simplifies commissioning and system management. For homeowners, the optional Smart WiFi Hub adds remote control, a feature that is increasingly in demand. For installers, the ability to run remote diagnostics and updates reduces callbacks and enhances the after-sales experience, which in turn benefits builders and builders merchants by ensuring stronger long-term customer satisfaction.
With sustainability a central requirement in construction, the Aerona R290 delivers on this front as it uses natural refrigerant R290, which has an impressively low Global Warming Potential (GWP) of just 3. This, combined with its A+++ energy rating, allows builders to meet and exceed current energy efficiency standards and ensures that projects remain future-proof as Ireland’s housing sector continues its transition towards low carbon heating solutions.
To support those working in the industry, Grant offers comprehensive training programmes. A one-day installer course at the Grant Training Academy covers installation, commissioning, servicing, and safe handling of R290 refrigerant, while eLearning options provide flexibility for teams to train at their own pace and location.
With over 20 years of expertise in heat pump technology and a long-standing reputation for innovation and quality, Grant is committed to supporting Ireland’s construction industry as it transitions to more sustainable heating solutions. The Aerona R290 represents the latest stage in this commitment, offering a practical, regulation-ready system that meets performance goals while also supporting long-term Environmental targets.
For builders, it ensures smooth, efficient project delivery. For builders merchants, it provides a trusted, in-demand product that strengthens customer relationships and future sales opportunities.
