Visit us at ElementalLONDON 2025

We’re excited to be exhibiting at elementalLONDON 2025, where we’ll be showcasing our bestselling range of UK-manufactured boilers, designed to deliver flexible, powerful heating solutions for both the domestic and commercial market.

Join us on STAND B44 to explore our leading range of twin flue boilers and accessories, including:

Combi 2 & System 2 Twin Flue Boilers

Featuring a sleek and lightweight design for simple installation, Combi 2 and System 2 boilers are designed for use in both new and retrofit projects. Offering greater flexibility through the Keston twin flue system, boilers can be sited up to 27 meters* from the flue outlet, which is an important consideration for long or challenging flue runs.

Keston High Rise Flue Kit

Compatible with both Combi 2 and System 2 boilers, our popular High Rise Flue Kit provides a versatile solution developed to meet the specific needs of high-rise building applications following changes to the building regulations.

Suitable for all buildings in England and Wales higher than 18 meters, the kit is fully compliant with: The Building Regulations 2020, Part B – Fire Safety, Volume 1, which require that, amongst other conditions, materials which become part of the external wall in relevant buildings do not contribute to external fire spread. Our High Rise Flue Kit is also suitable for installations in Scotland above 11 meters, in accordance with the Building Standards Technical Handbook 2020: Domestic Buildings.

Made from high-quality 316 stainless steel, the Keston High Rise Flue Kit provides a robust, corrosion resistant alternative to other non-combustible or fire-resistant materials such as aluminium.

Heat 2 Twin Flue Boilers

Available in outputs of 45kW to 55kW, our Heat 2 boiler range features up to 18m of twin flue capability*, offering a flexible solution for challenging installations. What’s more, Heat 2 boilers can also be cascaded using our frame and header kits, to achieve combined outputs of up to 330kW.
