Grant Vortex Boiler House 46/70
The Grant Vortex Boiler House 46/70 is designed to deliver reliable, efficient heating performance in a compact and practical package. Part of Grant's distinctive Vortex Boiler House range, it combines high efficiency with a striking powder-coated casing in Grant's iconic red, making it easy to recognise while delivering dependable day-to-day performance.
The Boiler House range uses the same trusted technologies found across other Grant Vortex boilers, including unique stainless steel heat exchangers. Combined with the latest Riello low NOx burner technology, the range is designed to provide efficient operation while helping to keep running costs under control.
Power and Efficient Performance
The Grant Vortex Boiler House range is available in outputs from 15kW up to 70kW, providing options for properties and applications with a wide range of heating requirements. With space heating efficiencies of up to 91.7%, the boilers are designed to make effective use of fuel while delivering reliable heat.
The externally mounted Riello RDB burner is a key feature of the Boiler House design and incorporates low NOx technology, helping the boiler deliver efficient combustion with reduced nitrogen oxide emissions.
Compact Boiler House Design
Despite its impressive heating capabilities, the Boiler House range has a compact design that makes it particularly suitable for installations where indoor living space needs to be preserved. The boilers are well suited to garages, plant rooms and cellars, providing a practical way to position the heating system away from the main living areas.
The distinctive powder-coated red casing not only gives the boiler its characteristic Grant appearance but also provides a durable external finish.
Flexible Installation and Biofuel Compatibility
The Grant Vortex Boiler House range is compatible with Grant EZ-Fit flue systems, providing installers with added flexibility when planning the flue arrangement.
The range is also biofuel compatible, depending on the type of biofuel and the percentage blend being used. This offers potential flexibility for installations where an approved biofuel blend is being considered, subject to the relevant compatibility requirements.
Guarantee and Peace of Mind
A 5-year guarantee is available when the boiler is installed by a G1 Installer, subject to the applicable terms and conditions. This provides additional reassurance when choosing the Grant Vortex Boiler House range for a new installation or replacement heating system.
