In heat pump specification, performance claims are no longer enough. Increasingly, contractors, consultants and building engineers are looking for clear, comparable data they can trust when assessing how systems are expected to perform.
Consistent and regulated basis
This shift is placing greater emphasis on ErP fiche data – standardised performance information defined under EU regulations, which enables direct, like-for-like comparison between products. For engineers responsible for system design and performance modelling, it provides a consistent and regulated basis for assessing expected performance under defined test conditions.
With decades of experience in heating technology and a strong reputation across the Irish market, Grant has built its position on delivering reliable, high-performance solutions. It is within this context that the Grant Aerona R290 heat pump range is setting a new benchmark.
Grant Aerona R290 4kW, 6kW and 12kW heat pumps.
Rather than relying on isolated performance figures, the Aerona R290 provides transparent performance data across its full range, which is available in outputs from 4kW to 16kW. All performance data is declared in line with EU standardised test conditions and independently verified by TÜV SÜD, offering an additional layer of assurance when assessing system performance across different applications.
Across the range, all models achieve A+++ energy ratings under low-temperature conditions. Seasonal space heating efficiency remains consistently high - exceeding 200% in smaller units and maintaining close to 190% even at larger outputs.
In practical terms, this indicates that the system can deliver approximately twice the heat output relative to electricity input under standardised test conditions, which is an important factor in evaluating both energy performance and expected running costs.
What sets the Aerona R290 apart is not just this level of efficiency, but the consistency with which it is maintained. As system sizes increase from 6.5kW to 16kW, performance remains stable and predictable, providing confidence when designing systems across a range of property types and heat demands.
Annual energy consumption data further supports system design, with values ranging from approximately 1,600 kWh for smaller units to over 6,600 kWh at higher capacities. This enables more accurate BER modelling and more informed assessment of operational costs.
Durability and efficiency
Designed in Ireland specifically for Irish and UK climate conditions, the Aerona R290 heat pump has been engineered to perform reliably in high-moisture, variable environments where consistent output can be a challenge for some systems. Extensive in-house testing supports durability and efficiency across a wide range of operating conditions.
The system also utilises natural refrigerant R290, which has a Global Warming Potential of just three – significantly lower than conventional alternatives such as R32 – supporting reduced environmental impact while maintaining high levels of performance.
As building standards continue to evolve, so too must the criteria for product selection. Working with a trusted manufacturer and specifying systems with clear, proven performance data is essential in delivering compliant, efficient and future-proofed projects.
Grant’s approach focuses on delivering heating solutions that combine performance, reliability and ease of installation. In an increasingly regulated market, this is underpinned by the provision of clear, standardised and independently verified performance data to support confident system specification.
The Aerona R290 is not just another heat pump - it reflects both the evolution of heating technology and the importance of experience, trust and demonstrable performance within the Irish construction industry.
