This Grant Vortex Boiler House Boiler is perfect for hard-to-access areas where a white cased utility boiler is less desirable, such as a cellar or plant room. The boiler features an eye-catching powder-coated casing in Grant’s iconic red, giving it a distinctive appearance.
Highly efficient, it also offers exceptional performance, boasting low running costs and space heating efficiencies of up to 91.7%.
On top of the same technologies utilised by other Grant boiler models, the boiler has an externally mounted Riello RDB burner, a unique stainless steel heat exchanger, and the latest Riello low NOx burner technology. It’s biofuel-compatible and is also compatible with Grant EZ-Fit flue systems.
For peace of mind, the boiler comes with a 5-year guarantee when installed by a G1 installer, subject to Grant’s terms and conditions.
