With increasing demand for low-carbon heating technologies, higher building performance standards and future-ready design, engineers require heating solutions that deliver performance, compliance and long-term operational reliability.
Grant’s Integrated Heating Packages provide a co-ordinated approach to heating system design, supporting accurate specification for new-build homes and residential developments across Ireland. The free of charge service is widely used across the sector, helping engineers to save valuable time on new build and deep retrofit projects.
Developed by the company’s in-house technical team, each system brings together the key components of a modern low-carbon heating solution, including a primary heat source, hot water storage and carefully selected heat emitters, with optional smart controls. Every system is designed to reflect the specific layout, calculated heat demand and regulatory requirements of the property, helping to ensure predictable performance while reducing design risk.
At the centre: The award-winning Aerona R290 heat pump
At the heart of Grant’s integrated heating packages is the Aerona R290 air-to-water air source heat pump, a high-efficiency system that uses natural refrigerant R290, which has a global warming potential (GWP) of only three, supporting long-term decarbonisation goals.
Grant Aerona R290 4kW heat pump.
Designed in Ireland for the Irish and UK climate, the Aerona R290 has received recognition for its design and performance. Available in five output sizes ranging from 4kW to 16kW, the Aerona R290 offers flexibility across a wide range of property types. Achieving A+++ ErP ratings, with SCOPs up to 4.88. The system is capable of 75°C flow temperatures, however correct system design will ensure that a lower more efficient flow temperature is utilised.
Design support from start to finish
As part of Grant’s Integrated Heating Design and Specification Service, engineers benefit from full system design support including detailed room-by-room heat-loss calculations, system sizing, product selection and technical guidance.
For those working across one-off dwellings or larger housing schemes, this approach helps support alignment with current building regulations and energy performance targets from the start of the design stage. The result is a coordinated system specification that supports smoother planning, installation and commissioning.
Complete system design
To complement the Aerona R290, Grant’s integrated heating package solutions include the specification of compatible hot water storage and heat emitters.
Grant Uflex underfloor system.
Depending on project specifications, this may include Grant Uflex underfloor heating, Afinia aluminium radiators, or a combination of both. Hybrid emitter layouts are commonly used to optimise system efficiency, while delivering responsive comfort and accommodating architectural requirements across different zones within the property.
System integration is completed through the Aerona Smart Controller, which comes with all Aerona R290 heat pumps and enables scheduling, weather compensation and remote access. This allows homeowners to manage their heating easily while also supporting monitoring and diagnostic capabilities for installers and engineers, helping to maintain long-term system performance.
Grant’s Integrated Heating Packages provide engineers with a structured and technically supported approach to low-carbon heating design. By combining award-winning heat pump technology with coordinated system components and technical design support, the packages help reduce complexity and support the delivery of compliant, future-ready homes across Ireland.
