With an A+++ energy rating at a 35°C flow temperature, the Aerona R290 has been rigorously tested at -5°C air temperature with a 55°C water flow, ensuring it can handle extreme weather conditions while maintaining top efficiency. For plumbing and heating
Grant has once again raised the bar in renewable heating technology with the launch of its Aerona R290 air-source heat pump — a system designed specifically for the challenging climate conditions of Ireland and the UK. Built for efficiency, reliability and sustainability, this next-generation heat pump is a game-changer for homeowners, self-builders and the construction industry. With five models available, ranging from 4kW to 16kW, the Aerona R290 offers a level of flexibility unmatched in the market. Whether for a newbuild project, home extension or an upgrade to a more efficient heating system, this unit ensures consistent performance and lower energy costs.
frost on outdoor coils. In foggy or rainy conditions, when temperatures drop, moisture in the air can freeze on the unit, triggering frequent defrost cycles that reduce efficiency and increase energy consumption. Recognising this issue, Grant invested €2.4m/£2m in developing and testing the Aerona R290 to perform exceptionally in Irish and UK weather conditions. The result is a high-performance heat pump that minimises heat loss from defrosting, ensuring stable operation even in high- moisture environments.
WHY THE AERONA R290 STANDS OUT
The Aerona R290 series is currently the only heat pump range in its category to have been designed specifically to perform in the Irish and UK climate. Additionally, it is also currently the only range of its type to provide such a diverse range of outputs, making it adaptable to a variety of property sizes and heating demands.
OPTIMISED FOR UNPREDICTABLE WEATHER CONDITIONS
One of the most common challenges with air-source heat pumps in wet and cold climates is the accumulation of
