Leading heating technology manufacturer, Grant, is widely acclaimed for its forward-thinking approach to research and developing innovative heating technologies and operates at the forefront of the industry with its highly efficient and reliable integrated heating solutions.
Barry Gorman, National Renewable Sales Manager at Grant, explains how the company remains dedicated to developing sustainable heating technologies to support decarbonisation efforts. He also recommends the Grant Aerona³ air-to-water air source heat pump as the ideal primary heat source for new build properties.

“At Grant, our primary focus is to deliver innovative, reliable, and cost-effective heating solutions to address the challenges of rising energy costs and carbon emissions, aiming to secure a greener future for generations to come. While we began developing boilers over 45 years ago, our team has spent the past two decades creating highly efficient, sustainable heating technologies such as the A+++ Aerona³ R32 air-to-water air source heat pump and its supporting technologies.”
Providing discreet, high-quality heating, the Grant Aerona³ R32 air-to-water air source heat pump has quickly become a popular choice among property developers, heating engineers, and architects working on new builds, particularly those designed to complement the heat pump. With an ErP rating of A+++, this range is available in outputs of 6kW, 10kW, 13kW, and 17kW.
In many cases, the Aerona³ has become the preferred heat source due to its cleaner, more environmentally friendly performance and its ability to reduce a property’s overall carbon footprint and ultimately helping the property to achieve the current building standards and regulations.
Barry added, “The Grant Aerona³ air source heat pump is not only renewable, but it is also highly popular among those designing new properties due to its excellent compatibility with our range of supporting technologies. These include the pre-plumbed and integrated hot water cylinders, as well as a variety of heat emitters including the Grant Uflex underfloor heating system and the Grant Afinia aluminum radiators, along with smart heating controls. The Grant Afinia aluminum radiator range offers a sleek, high-efficiency option with excellent conductivity, while the Uflex underfloor heating system is an ‘invisible’ heat emitter, often preferred by architects for heating larger, open-plan rooms. Both options provide great flexibility for new builds, seamlessly integrating with the Grant Aerona³ R32 air-to-water air source heat pump.”
