When selecting a heating system - especially for buildings where standard installations are difficult - flexibility is key. This is where Keston twin flue boilers truly stand out. From high-rise flats and heritage properties to sites with restricted access, Keston twin flue boilers provide a versatile and reliable heating solution when other systems might hit logistical roadblocks.
At the heart of Keston’s innovation is its twin flue technology. Unlike conventional systems that use a concentric flue - combining air intake and exhaust into a single pipe and requiring installation near an external wall - Keston’s unique design separates these functions into two individual pipes. This allows for vertical or horizontal flue runs of up to 27 metres*, giving installers far greater scope and adaptability. Whether it’s a basement, loft, internal room, or a building without direct access to an outside wall, Keston twin flue boilers offer a safe, efficient solution that can be installed almost anywhere.
This flexibility is particularly important when considering strict regulatory requirements, such as where boiler flue position regulations demand that flues be placed at a certain distance from windows and doors.
Keston’s wall-hung boilersare also designed with space efficiency in mind. Their compact, lightweight build means they can fit into tight spaces like kitchen cupboards or small utility rooms, making them perfect for buildings with limited space. Despite their small footprint, Keston twin flue boilers deliver a powerful and consistent performance that can easily rival larger systems, making them suitable for everything from modest flats to larger properties with more demanding heating needs.
Energy efficiency is another major strength. All Keston models are A-rated, helping to reduce both energy bills and environmental impact. All models also feature modulating burners that automatically adjust the boiler’s output to meet real-time heating demand. This ensures consistent, comfortable temperature and helps extend the boiler's lifespan. With added features, such as weather compensation and compatibility with smart thermostats, users can also benefit from enhanced control, convenience, and year round energy savings.
Finally, Keston twin flue boilers are engineered with the installer in mind. Thanks to their twin flue setup and neatly arranged components, they can be easily accessed for routine maintenance. This results in less disruption during installation, faster servicing, and more reliable long-term performance.
