Grant continues to set the benchmark in Ireland’s heating industry with its range of high-efficiency, innovative technologies and customer-focused services. As the demand for sustainable and cost-effective heating systems continues to grow, Grant remains at the forefront by offering integrated solutions that are technologically advanced and also tailored to the individual needs of each home.
From the award-winning Grant Aerona R290 air-to-water heat pump to the highly efficient Uflex underfloor heating system, Grant’s heating technologies are specifically designed to work together to maximise system performance and deliver long-term cost and carbon savings. These systems are particularly well suited to new build and deep retrofit projects, where high efficiency and low environmental impact are key considerations.

A popular service offered by the heating technology manufacturer is its complementary Heating Design Service – a value-added solution that ensures each heating system is precisely matched to the property. This free service includes room-by-room heat loss calculations in line with S.R. 50/MCS requirements, based on detailed assessment of house plans. Grant’s technical specialists then recommend the most appropriate main heat source and supporting technologies such as integrated hot water storage and heat emitters like Grant Afinia aluminium radiators and / or Uflex underfloor heating.
When the Aerona R290 heat pump is selected, customers benefit from one of the market’s most efficient and environmentally friendly heat sources. Designed specifically for the Irish climate, the A+++ rated Aerona R290 range is available in 4kW, 6.5kW, 9kW, 12kW, and 16kW models, each with a SCOP of 4.8 at 35°C flow temperature. Additionally, the Aerona R290 range performs at ambient temperatures as low as -5°C and features a high-capacity circulation pump and integrated immersion heater which reduces installation time and cost.

Keeping in line with planning and design trends, the Aerona R290 unit’s black monobloc casing provides a clean, modern aesthetic placement, while its ultra-quiet operation thanks to acoustic insulation and anti-vibration technology, addresses growing concerns about sound pollution in high-density settings.
Each model is also recognised by Quiet Mark for its ultra-quiet operation, which is particularly relevant in compact developments and shared housing schemes.
The Grant Uflex underfloor heating system perfectly complements the Aerona R290, offering an efficient, discreet heat emitter ideal for modern and minimalist interior spaces. Suitable for both high and low-temperature systems, Uflex is designed and sized room-by-room by Grant’s technical specialists, ensuring optimal performance. The system’s stainless-steel manifold, self-adhesive edging strip with a unique ‘skirt’ design, and flow screed foundation contribute to its consistent heat delivery and ability to act as a thermal store. Uflex underfloor heating also helps reduce heat loss where the floor meets the wall and integrates seamlessly into the overall construction timeline, with no delays in the building process.
All Grant technologies are built around a philosophy of total system integration – meaning each component is designed to work in harmony with the others for maximum efficiency, user comfort, and installer ease.
