Product Information

Grant Vortex Eco External Wall Hung 16-21kW Boiler Only

The Grant Vortex Eco External Wall Hung 16-21kW Boiler Only is a practical and efficient heating solution designed for outdoor installation. With its wall-mounted design, it is particularly useful for properties where outdoor floor space is limited. By positioning the boiler on an external wall, it can help make better use of the available space while providing reliable heating performance. The External Wall Hung range offers homeowners a choice of system configurations, with two sealed system models and two open-vented system models available. This range of options makes it easier to choose a boiler that suits the requirements of the property's heating system and installation.

Efficient 16-21kW Performance

Available with an output of 16-21kW, the Grant Vortex Eco External Wall Hung boiler is designed to provide dependable heating for a range of properties. The models achieve space heating efficiencies of 90.13-90.5%, helping to deliver effective heating while making efficient use of energy.

Designed for Outdoor Installation

The boiler features a high-quality external powder-coated casing designed to withstand outdoor and all-weather conditions. Built-in frost protection provides additional protection during colder weather, making the boiler well suited to external installation throughout the year. A factory-fitted multi-directional flue is supplied with the boiler, providing flexibility when positioning the unit and helping to simplify the installation process. The boiler also operates quietly, making it a suitable choice for residential properties.

Flexible Wall-Mounted Design

The wall-mounted design makes the Grant Vortex Eco External Wall Hung an ideal option where outdoor floor space is restricted. Rather than requiring valuable ground-level space, the boiler can be mounted externally, offering homeowners greater flexibility when deciding where their new heating system should be installed.

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. Combined with its durable external casing, frost protection and efficient operation, the Grant Vortex Eco External Wall Hung range provides a practical heating solution for outdoor installation.

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.
