Our thoughts
The Grant Vortex Eco is a high-performance and quiet boiler. It is great if you don’t have access to the gas network.
Unfortunately, Grant are moving away from Blue Flame technology. We’re not sure why. Blue Flame technology will allow bio-oils to be burned, reducing the usage of fossil fuels. They haven’t been released yet, however.
We no longer recommend Grant boilers when a Navien boiler is an option for your home.
Excellent service and quality
Grant has won awards for its boilers. Designed and manufactured in the UK, they have a reputation for reliability and performance. They also have an excellent all-round reputation, including customer service. The Trustpilot page for Grant has a Great rating based on over 2.300 reviews (as of January 2024).
Choose the right model for your needs
The Grant Vortex Eco oil boiler is available as a regular/conventional boiler. You can purchase a kit to convert it to a sealed system boiler. The right Vortex Eco model for you will depend on the current heating setup in your property.
Built to last
The external models in this range feature high-quality powder-coated casing designed for all weather conditions. This makes them highly durable. They also include built-in frost protection, with a mains isolating switch and test switch.
Reduce gas and electricity consumption
The UK is now committed to achieving a net-zero emissions rating within the next decade. The energy market remains volatile, so seeking an economical boiler should be a priority for homeowners.
A Grant oil boiler can reduce your household’s carbon emissions and save money on your energy bills. The stainless steel heat exchanger provides optimal heat transfer and ensures retained efficiency for the boiler’s service life.
