Each Vortex Pro External oil boiler combines Grant’s proven condensing boiler technology with the latest Riello RDB compact burner.
Grant 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. Sealed system kits are also available for these oil-fired boilers, and each model has a factory fitted frost stat and condensate state.
Grant’s oil boilers incorporate several design features which enable each model to work most efficiently. Each boiler utilises the patented Vortex stainless steel condensing heat exchanger and turbulator baffle system, enabling the boilers to extract energy from the latent heat which would normally be lost through the flue. This award-winning technology has been recognised throughout the industry and it is popular with heating engineers and householders alike.
One of the many reasons installers choose Grant boilers is the choice available, with a boiler to suit many installation applications. View the complete boiler range here.
