Our rigorous research & development procedures and manufacturing quality control checks ensures that all of our products are produced to the highest of standards, delivering total comfort and peace of mind. The design of our British built boilers is optimised to ensure compact dimestions, a lower the component count in order to maximise reliability, and to offer a low installation lift weight.
Keston boilers are offered with a warranty of up to 7 years (Keston System and Combi: 5-year parts & labour warranty as standard. 7-year warranty when installed with a Keston 22mm System Filter and registered within 30 days of installation. Terms and conditions apply), ensuring the ultimate peace of mind for both you and your customer.
The Keston domestic boiler range is made up of Combi and System boilers, offering a solution for all applications. Every model in the range offers a market leading solution for awkward and problematic installations, thanks to the twin flue capability.

The Keston Twin Flue system makes every job easier. To give you maximum flue flexibility, you can run the flue vertically or horizontally from an elevation of 1.5° and the flue can be extended up to 27 metres from the boiler allowing for easy and hassle-free installation.
A low cost, small diameter (50mm) muPVC (PVC-C) pipe (Marley, Polypipe 2000 System, Polypipe Terrain 200 and Wavin Osma systems only) is the only item required for use with the innovative Keston flue and air intake system. This is readily available from your local merchant at a fraction of the cost of concentric flue. The Keston flue system makes every job easier. To give you maximum flexibility, you can run the flue vertically or horizontally from an elevation of 1.5°) and the flue can be extended up to 27 metres from the boiler allowing for easy and hassle-free installation.
