Our thoughts on the Grant Vortex Eco Oil Boiler

The Grant Vortex Eco Oil Boiler is a high performance and quietly operating model. If you do not have access to the gas network, it could be worth considering an oil boiler such as the  Grant Vortex Eco Oil Boiler, as it is biofuel compatible, which can also reduce your home’s reliance on fossil fuels and your carbon footprint.

Excellent service and quality

Grant has won awards for its boiler models. Designed and manufactured in the UK, they have a reputation for reliability and improving performance. However, they also have a good all-round reputation, including for customer service. The Trustpilot page for Grant has an Excellent rating, based on over 1,800 reviews.

Choose the right model for your needs

The Grant Vortex Eco Internal Oil Boiler is available as a combi, system or regular boiler, in a wide range of kW sizes. A combi boiler heats water directly from the mains, as well as providing energy for central heating from one unit. This instantaneous heating will reduce energy waste and help to minimise water inefficiency in your home. A system boiler requires a cylinder and can supply hot water to multiple taps simultaneously. A standard boiler uses a storage tank to heat water. The right Vortex Eco model for you will depend on the current system in your property, your water usage and the number of bathrooms 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 extremely 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. As integration with biofuels is also possible with this boiler, you can also use this boiler to switch to renewable alternatives.
