Grant continues to support the deployment of renewable home heating technology

With more than four decades of innovation, quality and high performance at the company’s core, Grant is supporting two important research initiatives aimed at reducing or eliminating the risk of low-income households being left behind in the transition to clean, smart, integrated energy systems.

The first of these initiatives supported by Grant is RULET – Rural-Led Energy Transition – led by the Ulster University and the Northern Ireland Housing Executive (NIHE). The initiative is part of the SPIRE 2 (Storage Platform for the Integration of Renewable Energy) project which is a €6.7m EU-funded, cross border project aimed at evaluating, developing, and facilitating the wide-scale deployment of consumer-owned energy storage technologies, to operate profitably in the changing energy markets in Ireland and the UK. 

RULET is focused on making the full benefits of smart energy technology available to the most vulnerable households in the western counties of Northern Ireland, a wind energy hotspot. This includes the installation of the Grant hybrid heat pump system which has been specially designed for social housing.

The first part of the RULET project aims to enable people to avail of agile tariffs – by running Grant heat pumps at a lower tariff – when wind energy is available and when there is flexibility to run an HVO biofuel fuelled boiler when the electricity grid is at its maximum capacity. This in turn allows energy providers and the homeowners greater flexibility around tariffs and energy requirements. 

Continuing to support the deployment of renewables across the UK and Ireland, Grant has also collaborated with seven partners across five European countries, as part of the EU funded HANDIHEAT project. The aim of HANDIHEAT is to improve the energy efficiency and renewable solutions in housing and rural communities. This includes improved thermal comfort and reduced energy bills.

In Fermanagh, six Northern Ireland Housing Executive homes had their cavity wall insulation improved and two low carbon, electric heating models were installed. This included the Grant Aerona3 R32 heat pump used in a hybrid model, working with a Grant Vortex condensing oil boiler. In this hybrid model the heat pump takes the lead in heating the property with the condensing oil boiler used during the colder weather.

The Grant A+++ Aerona3 R32 air to water air source heat pump used in both the RULET and HANDIHEAT projects, is Grant’s most sustainable main heat source. Available in four outputs of 6kW, 10kW, 13kW and 17kW, the Grant Aerona3 R32 has quickly become a popular choice amongst plumbers and installers due to its cleaner, more environmentally friendly performance, and its ability to lower a property’s overall carbon footprint.

Commenting on the company’s involvement in these initiatives Barry Gorman, National Renewables Sales Manager at Grant said, “We are delighted to be supporting both of these important initiatives and helping to advance the deployment of renewables throughout Ireland and the UK. Our hybrid heat pump system allows a 6kW Grant Aerona3 R32 air to water air source heat pump to run in tandem with an existing boiler installation. Following basic energy efficiency upgrades carried out by the Northern Ireland Housing Executive, the hybrid system runs at high efficiency using wind energy stored overnight which in turn helps to significantly reduce fossil fuel consumption and carbon emissions.”
