Offaly company invests €2.4 million in new generation heat pump designed for Irish climate

Globally renowned heating technology manufacturer Grant, with headquarters in Birr, Co. Offaly has announced the launch of its new-generation air source heat pump – the Grant Aerona R290, representing an investment of € 2.4 million.

Further demonstrating Grant’s commitment to innovation and position as a leader in sustainable home heating, the Aerona R290 was designed in Ireland, specifically for the Irish and UK climate and is already proving itself to be in another league in terms of innovation and efficiency and a significant addition to the Grant product portfolio.

Throughout the research and development phase, Grant invested heavily in the 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.

Stephen Grant, Founder of, Grant said, “The launch of the Aerona R290 heat pump marks a significant development in sustainable home heating and within our product portfolio. As our new-generation heat pump, the Aerona R290 comes as Grant celebrates 15 years of being in the heat pump market and is a testament to our commitment to design highly efficient, reliable heating technologies which can make a real sustainable difference. As more homes make the transition to lower carbon heating solutions, we look forward to continuing to support customers through the delivery of technologies, products and services that can help them make a real difference.”

The Aerona R290 heat pump range has been designed to suit many types of homes and features five models, with outputs of 4kW - 16kW, which can be monitored and managed remotely, giving installers and their customers full control of their heat pump system and the ability to provide offsite diagnostic support.

The A+++ energy rated Aerona R290 provides an even more environmentally friendly, low carbon heating solution for the next generation as it uses the energy efficient and natural refrigerant R290, which has an incredibly low Global Warming Potential (GWP) of 3 compared to other refrigerants commonly used in heat pumps like R32 which has a GWP index of 657, signalling an important advancement in sustainable home heating.

Speaking about the design of the Aerona R290 heat pump, Grant R&D Manager, Peter Darcy said, “When designing the new heat pump we listened carefully to our customers. Not only did this influence the aesthetic look of the unit but also the acoustic qualities and of course the performance. Reliable high efficiency, sustainability and maximum comfort were also important elements and the Aerona R290 delivers on all of these.”

Alongside the new Aerona R290 heat pump range, Grant is also launching the Aerona Smart Controller, and QR Smart Pre-Plumbed AWave Integrated Cylinder. These new products will feature within the company’s integrated heating package solutions, providing further choices and flexibility for design and installation whilst providing the same quality and reliability that they have come to expect from a Grant heating system.
