In order to ensure long-term heating efficiency, the in-house technical team at Grant collaborated with Woodfort Group and Total Energy Plumbing & Heating Ltd to size and specify a bespoke heating solution for each home. All heating technologies were provided by SKC Providers, based in Rathnew.

For a cleaner, more environmentally friendly home heating solution, a 6kW Grant Aerona³ R32 air-to-water heat pump was installed in the properties as the main heat source, which can achieve a high seasonal coefficient of performance (SCOP) and is sustainable at low temperatures. The Grant Aerona³ range has an ErP of A+++, is amongst the most efficient air-to-water heat pumps in Ireland and is easy to install with its compact size. Furthermore, the Grant Aerona³ range helps to achieve required compliance in line with Part L of the building regulations and, when partnered with a renewable electricity supplier, will generate extremely low carbon heat for homeowners.

The installation in Co. Wicklow also included a 210 litre Grant pre-plumbed hot water cylinder as part of a Grant Integrated Unit to supply the properties with 24/7 hot water.

Grant’s Integrated Unit has been designed to heat water faster and more efficiently than standard cylinders, while being easy to install and operate.

Grant Aerona³ heat pump key features:

• Range available in 6kW, 10kW, 13kW and 17kW
• Quiet Mark
• 5-year guarantee
• Built-in weather compensation
• Single phase
• Built-in circulating pump

Grant’s in-house technical team works with developers, self-builders, specifiers, and engineers daily to design one-of-a-kind integrated heating systems for projects ranging from one-off new builds to multi-home developments. After carrying out in-depth heat loss calculations for each room of the property, the Grant team will design, size and specify individual heating systems free of charge, to ensure each property’s heating system performs to its optimum efficiency, providing comfort and long-term cost savings for the homeowner.
