For over four decades Grant’s innovative heating technologies have become a popular choice for many home heating systems across the country. This is mainly due to their reliability, high efficiency, ability to reduce carbon emissions and provide affordable heating solutions for both existing homes and new builds.
If you are considering the move to renewable energy or are building a new home, Grant has outlined options available to you to help ensure you future-proof your home for its changing heating needs with a sustainable heating system.
If you are one of the 60 per cent of existing Irish homes that live off the gas grid and are using an old oil boiler to heat your home, then upgrading to a condensing boiler like the Grant Vortex HVO biofuel ready condensing boiler is an option to consider. One of the first condensing oil boilers on the market, the Grant Vortex has been the boiler of choice for many heating upgrades and was the catalyst for a sustained increase in boiler efficiencies throughout the industry and a reduction in running costs for homeowners. The higher efficiencies from these appliances have, over the past two decades, contributed to a reduction in carbon emissions in Ireland amounting to many millions of tonnes.
In recent years, Grant innovated its Grant Vortex range to enable the technology to run using 100 per cent hydrotreated vegetable oil (HVO) biofuel. All boilers within the Grant Vortex range come HVO biofuel ready and older Grant condensing boilers can be adapted to run on HVO biofuel, with required modifications being carried out by a service engineer during an annual service. This adaptability of the Grant Vortex range is helping homeowners reduce carbon emissions by 87 per cent and avoid the high costs and disruption to daily life caused by deep retrofitting.
Utilising HVO will also help Ireland to significantly decarbonise approximately 680,000 existing residential homes, at a cost of approximately €500 per existing oil boiler installation when matching and changing to a new biofuel burner and substantially less if the boiler is already biofuel-ready.
For those planning or currently building a new build home, a heat pump is an ideal choice. Heat pumps are increasingly popular, due to their high energy efficiency, sustainability, and alignment with modern building standards. Air to water air source heat pumps use renewable energy from the air to provide home heating, making them a low-carbon alternative to traditional boilers.
New build homes, designed with superior insulation and airtightness, maximise the efficiency of heat pumps, which is why they aren’t recommended for older, existing homes unless the homeowner is in a position to carry out a deep retrofit to ensure their home is heat pump ready.
Grant has recently launched its next generation Grant Aerona R290 air to water air source heat pump which further demonstrates the manufacturers commitment to innovation and sustainable home heating.
Built upon three core pillars – design, performance and peace of mind, the A+++ energy rated Grant Aerona R290 heat pump combines modern styling with high performance. Designed to suit many types of homes, the Aerona R290 is best suited for year-round climate conditions in in Ireland and is available in five models with outputs of 4kW – 16kW.
In addition, the Grant Aerona R290 provides an even more environmentally friendly, low carbon heating solution for the next generation as it uses the energy efficient and natural refrigerant R290. Also known as propane, R290 refrigerant gas has an incredibly low Global Warming Potential (GWP) of 3, which is much lower than other refrigerants commonly used in heat pumps like R32 refrigerant, which is slowly being phased out, signalling an important advancement in sustainable home heating.
Innovative and aesthetically pleasing, models within the new Grant Aerona R290 heat pump range can also be monitored and managed remotely using the Aerona Smart controller which gives homeowners full control of their heat pump system from wherever they are, and if required their installer can provide offsite diagnostic support.
Heat pumps offer long-term cost savings on energy bills and help homeowners future-proof their properties in line with evolving environmental regulations and net zero targets. With government incentives, quiet operation, and models to suit all new build homes, heat pumps are an ideal choice for creating comfortable, eco-friendly living spaces.
In addition to the main heat sources mentioned above, the Grant product portfolio also includes ranges of supporting technologies including solar thermal panels, Uflex underfloor heating, hot water cylinders, Afinia aluminium radiators and smart heating controls.
