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.

Effectively controlling your Grant boiler
Modern day control systems can help homeowners to precisely manage their home heating, achieving maximum comfort with improved efficiencies. Room thermostats and controls deliver heat when and where it is most needed, reducing the demand when not required which consequently reduces the demand on the boiler.
