Product Information

Grant Vortex Eco External System Boiler

The Grant Vortex Eco External System Boiler is designed to provide efficient and reliable heating while offering the convenience of an outdoor installation. With a durable powder-coated casing, the boiler is built to be sited outside the home, helping free up useful indoor space without compromising on heating performance. The Eco External range features the same trusted components used in the Eco Utility models, combining dependable performance with excellent efficiency. Its outdoor design, built-in frost protection and robust casing make it a practical choice for homeowners looking to install their heating system externally.

Available Power Ratings

The Grant Vortex Eco External System Boiler is available in two power ranges: 15-21kW and 26-35kW. These options provide flexibility when choosing a boiler to suit different property sizes and heating requirements. Both the 15-21kW and 26-35kW variants are also available as sealed system models, giving installers additional flexibility when selecting the right heating system configuration.

Efficient Outdoor Heating

With excellent space heating efficiencies of 91.7-92.7%, the Grant Vortex Eco External System Boiler is designed to deliver effective heating while making efficient use of fuel. Both available power ranges offer the same focus on reliable and efficient performance. The boiler also operates quietly, making it a suitable option for residential properties where minimising external noise is important.

Durable External Design

The boiler features a high-quality external powder-coated paint finish designed to provide a durable casing for outdoor installation. Built-in frost protection helps protect the boiler during colder weather, while the mains isolating switch and test switch provide added convenience for operation and servicing. A factory-fitted multi-directional flue is supplied with the boiler, helping to save installation time and providing flexibility when deciding on the most suitable flue arrangement.

Guarantee and Peace of Mind

A 5-year guarantee is available when the Grant Vortex Eco External System Boiler is installed by a G1 Installer, subject to the applicable terms and conditions. This provides additional reassurance when investing in an efficient external heating solution.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
