Oil Boilers
The Grant Vortex condensing oil boiler range comprises of the most efficient and reliable oil fired boilers in Ireland.
Our condensing boiler range is available in 22 models with outputs from 15 – 70kW. The Vortex condensing oil boiler range comes in various models including boilerhouse, outdoor, combi and utility variants.
All new Grant condensing boilers are future-proofed to use HVO by making a slight modification to the boiler. Older Grant condensing boilers can also be adapted to HVO, these modifications can be carried out by a service engineer.
