The Grant Vortex Pro external models combine our existing proven condensing boiler technology with the latest Riello RDB low NOx compact burner.
The Vortex Pro External modules offer a factory fitted multi-directional flue, high quality external powder coated casing, built in frost protection, mains isolating switch and a test switch. The range has some of the highest energy efficiency ratings in the UK which not only significantly lowers fuel bills but also considerably reduces greenhouse gas emissions and lessens the environmental impact of domestic hot water and heating systems
a HeatingConsumer group Which? have published the results of their 2019 oil boiler survey. Amongst the range of products to receive Which? Best Buys this year are all of Grant’s Vortex Pro Utility oil boilers. This is the third year running that Grant boilers have achieved this accolade making them the only oil boiler brand to be awarded Which? Best Buys in 2017, 2018 and 2019.
The Which? Best Buy logo is widely recognised as an endorsement that reflects confidence, trust and reliability in products. The Which? Best Buys and the supporting surveys play an important role in the decision-making process for householders researching new appliances for their home. Grant Engineering is therefore thrilled to have the high-quality build of their Vortex Pro Utility models, for example, acknowledged in the latest Which? survey with Best Buy status.
