In most cases, the Grant Aerona3 R32 air to water air source heat pump is the main heat source of choice for a new build property or development. With an ErP rating of A+++ and a SCOP of up to 5.4:1, the Aerona3 heat pump range is available in outputs of 6kW, 10kW, 13kW and 17kW.

Offering cleaner, more environmentally friendly performance, the Aerona3 heat pump ensures required compliance is met in line with Part L of the building regulations. The 13kW and 17kW models are also recognised for their quiet operation by the internationally acclaimed Quiet Mark.

The Aerona3 heat pump is easily installed and works seamlessly with other Grant heating technologies to create a fully integrated heating solution. This full solution can be designed by Grant’s technical specialists free of charge to ensure all technologies are correctly sized and specified to maximise efficiency. Grant also commissions each heat pump at no extra cost.



Grant’s Uflex underfloor heating system continues to be the heat emitter of choice amongst those building modern, new homes, due to its suitability for a wide range of projects, from one-off new build projects and room extensions through to larger multiproperty developments.

The Grant Uflex underfloor heating system is a popular and versatile choice of heat emitter that works effectively with both high and low temperature systems, meaning it has the ability to work seamlessly alongside the Grant AeronaÑ R32 air to water air source heat pump. This has led to the two heating technologies becoming a popular duo within new build homes throughout Ireland.

The Uflex underfloor system can be fitted as part of the floor construction process, therefore causing no delays in construction, making this technology that bit more attractive to those working on new build homes

In recent years, Grant has largely transformed to a renewable heating company with its portfolio including ranges of air to water air source heat pumps, HVO biofuel ready condensing boilers, condensing wood pellet boilers, solar thermal panels, underfloor heating, hot water cylinders, aluminium radiators and smart controls
