Vortex Boiler House

The Grant Vortex Boiler House range is ideal for locations that are difficult to access such as cellars or plant rooms, where a white cased utility boiler is not always the best solution.

All Boiler House models come in a distinctive powder coated casing in Grant’s iconic red. The Riello RDB burner is externally mounted and the boilers feature the same technologies associated with other Grant boilers. With high efficiencies and low running costs, the Vortex Boiler House range is eye-catching in both appearance and performance.
