Grant Vortex Pro External Combi Boiler with Flue

Grant Vortex Pro External Combi Boiler with Flue

The Grant Vortex Pro External Combi Boiler with Flue is designed to provide efficient heating and excellent hot water performance while keeping the boiler outside the home. With three available models, the range offers flexibility for different heating requirements and is particularly useful for properties where indoor space is limited. The boilers feature larger-than-normal heat exchangers to help deliver strong hot water performance, while Grant's patented stainless steel heat exchanger technology supports efficient and reliable operation. With the boiler installed externally, homeowners can free up valuable space inside without compromising on heating or hot water performance.

Available Power Ratings

The Grant Vortex Pro External Combi range is available in three outputs: 21kW, 26kW and 36kW. This choice of power ratings allows installers to select a model suited to the heating and hot water requirements of the property. Across the range, space heating efficiencies range from 90.81% to 94.5%, providing impressive efficiency alongside dependable everyday performance.

Built for Outdoor Installation

The boiler features a high-quality external powder-coated casing designed for outdoor installation. Built-in frost protection provides additional protection during colder weather, helping the boiler remain suitable for external siting throughout the year. The outdoor design is particularly useful when indoor space is limited, allowing homeowners to keep valuable room inside the property available for other uses.

Enhanced Hot Water Performance

Large heat exchangers are used to help improve hot water performance, making the Vortex Pro External Combi a practical choice for homes where a strong supply of domestic hot water is important. Each model is supplied with a 24-litre expansion vessel, providing additional system capacity as part of the installation.

Flexible Installation and Easy Operation

A factory-fitted multi-directional flue is supplied with the boiler, helping to save installation time while providing flexibility when planning the flue arrangement. Neon diagnostic indicators make everyday operation more straightforward by providing clear information about the boiler's operating status. Combined with its practical external design, the Grant Vortex Pro External Combi offers a convenient heating solution for outdoor installation.

Guarantee and Peace of Mind

A 10-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 Pro External Combi for a new installation or heating upgrade.
