Grant Vortex




For over 45 years Grant’s innovative heating solutions have been helping to address the need to reduce carbon emissions, whilst contributing towards a greener future. The Grant Vortex was one of the first condensing oil boilers on the market and this unique product was the catalyst for a sustained increase in boiler efficiencies throughout the industry and reduced running costs for property owners. The higher efficiencies from these appliances have, over the past two decades, contributed to a reduction in carbon emissions on the island of Ireland amounting to many millions of tonnes.

Grant’s award-winning Vortex range can now also be fuelled by a renewable alternative to fossil fuels – 100% HVO biofuel. The range has been recognised by multiple award bodies for its ‘ahead of its time’ innovation, winning the ‘Best Renewable Energy Product’ at the SEAI Energy Show 2022 and a Finalist in the sustainability category at The Irish Times Innovation Awards 2021. The Vortex range’s biofuel compatibility is helping prepare properties for the introduction of renewable biofuel blends, and the product is the first of its kind within the Irish heating industry.

The Grant Vortex range is the most economical heating choice for those working on a heating upgrade project in an already existing property. Upgrading an older boiler to a Grant Vortex condensing boiler will help improve efficiency and reduce carbon emissions by up to 88%. In fact, depending on the age and make of a property’s current boiler, upgrading to a Grant Vortex could help save over 28%1 a year on heating bills.

While HVO is a relatively new fuel to Ireland, we are now beginning to see more HVO suppliers come to the island, with a recent announcement of a new facility having just opened in Co Cork by HVO biofuel ‘giant’, Green Biofuels2.

This adaptability means that builders can have peace of mind from knowing that when installing a new Grant Vortex condensing boiler it will be suitable for use with biofuel blends whilst still providing the reliability and efficiency that is synonymous with Grant and helping towards the move to a zero-carbon future. The Grant Vortex and Euroflame boiler ranges are available to those in the building and heating trade in 22 models with outputs from 15 – 70kW. The Vortex range comes in a range of models including boilerhouse, outdoor, combi and utility variants.

Grant’s innovative range of heating technologies continues to drive the heating industry forward towards achieving a zero-carbon future.
