With a commitment to sustainability, efficiency and reliability, leading heating technology manufacturer, Grant continues to deliver advanced solutions to the construction industry across Ireland. This includes significant investment in diversifying its product portfolio and enhancing services such as its Heating and Design Specification workflow

In many new-build properties today, the success of a heating system is determined long before installation begins. Decisions made at the design stage directly influence the installation, commissioning and long-term system performance. Whether for one-off dwellings or multi-unit developments, as projects expand and timelines remain tight, ensuring consistency at this stage is increasingly important to delivering efficient and future-proofed housing developments.

Having a clear and well-defined heating system design in place from the start can deliver measurable efficiencies on site, reducing late-stage design revisions. As housing developments grow, the ability to apply a standardised approach across multiple properties also helps streamline delivery and maintain alignment between design intent and on-site execution. Recognising the importance of this structured approach, Grant has enhanced its Heating Design & Specification Service through further investment in advanced digital design software.

Using the enhanced platform, Grant’s technical specialists carry out in-depth room-by-room heat-loss calculations, detailed sizing for radiators or underfloor heating systems and full pipework circuit layouts. Automated calculation processes help improve consistency across projects whilst reducing the time required to produce complete system specifications, enabling faster turnaround times and improved overall project efficiency.

For project teams working across multi-unit developments or individual residential projects, the availability of clear and detailed design outputs supports more efficient coordination throughout the build process. Annotated schematics, layout drawings and material schedules provide a defined reference point for installers and contractors, helping to keep projects moving efficiently from first fix through to commissioning.

Supporting compliance with recognised industry standards, the service incudes heat-loss calculations produced in line with S.R. 50 and MCS requirements. This provides a consistent basis for demonstrating alignment with relevant building regulations and energy performance requirements across both new build and retrofit projects.

The structured design approach also supports the effective specification of modern heat pump systems such as the Grant Aerona R290 air-to-water air source heat pump. Available in five outputs from 4kW to 16kW, the Aerona R290 range provides flexibility across a wide variety of property types. It also achieves A+++ ErP ratings, with SCOPs of up to 4.88.

While the Aerona R290 heat pump can deliver flow temperatures of up to 75°C, correct system design ensures lower, more efficient operating temperatures are achieved. When systems are properly sized and specified from the outset, installers can work with solutions aligned to property demand, supporting consistent performance across developments.

By combining digital design capability with practical technical support, Grant’s Heating Design & Specification Service provides a structured approach to heating system delivery. As housing developments continue to scale and project timelines remain a key focus, having clearly defined, consistent and well-documented heating system designs in place from the outset supports more efficient delivery across all stages of construction. This approach not only supports compliance and efficiency but also helps reduce design risk and minimise delays during installation and commissioning.

Supporting both large-scale developments and one-off homes, this approach ensures every system is designed, installed and commissioned to deliver consistent, long-term performance.
