For more than 45 years, leading heating technology manufacturer Grant has been developing innovative heating products for a range of properties across Ireland.

With high efficiency and sustainability as key factors in the design of today’s heating systems, Grant manufactures heating technologies which work seamlessly together to provide value for money to develop highly efficient, sustainable heating solutions and in-house services to benefit those working on new-build and deep-retrofit projects.  

Optimum efficiency

Specifically, the Grant Aerona³ air to water air source heat pump and the Grant Uflex underfloor heating systems work particularly well together to ensure optimum efficiency.

When manufacturing its wide range of products, Grant combines both its innovative and technical insight to develop heating technologies that will future-proof homes for years to come.

All technologies within the Grant portfolio have been designed to work seamlessly with each other which ensures ease of installation for the installer. This includes the Grant Aerona³ R32 air to water air source heat pump which is being installed as the main heat source within many new build properties across Ireland.

The Grant Aerona³ air source heat pump has quickly become a popular choice amongst those engineers working in the heating trade due to its cleaner, more environmentally friendly performance, and its ability to lower a property’s overall carbon footprint, which will ultimately help to achieve NZEB building standards.   

This highly efficient heat pump has an ErP rating of A+++ and is available in outputs of 6kW, 10kW, 13kW and 17kW. The 13kW and 17kW models have also been recognised for their quiet operation by the internationally acclaimed Quiet Mark.

All four models boast superior seasonal coefficient of performance (SCOP) and depending on climate conditions and demand on the heating system at the time, can deliver 4kW of heat energy for every 1kW of electricity used. 

Heat emitter of choice among heating engineers

Grant’s Uflex underfloor heating system continues to be the heat emitter of choice among heating engineers, due to its suitability for a wide range of projects, from one-off new build projects and room extensions through to larger multi-property developments.

The underfloor heating system’s ability to work seamlessly alongside the Grant Aerona³ R32 air to water air source heat pump has led to the two heating technologies becoming a popular duo within new build homes throughout Ireland.

Installers and engineers can have a bespoke heating system designed and specified for each room based on flow rates and heat loss calculations, by availing of Grant’s free heating design service.

This service helps save considerable time and provides assurance from knowing that the system is compliant in terms of Part L of the building regulations in the Republic of Ireland.

Think Heating. Think Grant.
