For over 45 years Grant’s innovative heating solutions have been helping to address the problem of rising energy costs and reducing carbon emissions, whilst contributing towards a greener future. This is now more important than ever given the current rise in annual heating spending affecting property owners and households across the country.
Following the company’s development of HVO biofuel condensing boilers, Grant has largely transformed to a renewable heating company. Its portfolio includes ranges of Hydrotreated Vegetable Oil (HVO) biofuel boilers, condensing pellet boilers, solar thermal panels, underfloor heating, hot water cylinders, aluminium radiators, and air to water air source heat pumps.

The Grant Aerona3 R32 air to water air source heat pump continues to be a popular choice amongst those in the building trade for new build properties as it offers cleaner, more environmentally friendly performance and can also help a new build property achieve compliance in line with Part L of the
Building Regulations. With an ErP rating of A+++ and a SCOP of up to 5.4:1, the Grant Aerona3 is available in outputs of 6kW, 10kW, 13kW and 17kW. The 13kW and 17kW models are also recognised for their quiet operation by the internationally acclaimed Quiet Mark.
For heating upgrades in existing properties, the award-winning Grant Vortex condensing boiler range can help to futureproof a property with its ability to run also using Hydrotreated Vegetable Oil (HVO). All boilers within the range come HVO ready and older Grant condensing boilers can be adapted to run on HVO, with required modifications being carried out by a service engineer during an annual service.
This adaptability of the Grant Vortex range is helping immensely with the move towards a low carbon future, whilst still providing the reliability and efficiency that is synonymous with Grant.
