Glow-Worm Flexicom CX Combi Boiler

The Glowworm Flexicom cx range is amazingly flexible and surprisingly compact. The latest Glowworm range of condensing combi boilers offers a fantastic level of high efficiency heating performance. Flexicom cx boilers are available in 24kW and 30kW models and come equipped with a number of features designed to make installing these appliances simple.


The only condensing boiler in the UK with a direct rear flue option means you can fit a flexicom almost anywhere. Extensive flueing options are a feature of all new Glowworm boilers, allowing much greater flexibilty when it comes to installation. There is no need to remove the front case during installation thanks to Glowworm's pull out electrical connections block.


The small case size of the Flexicom cx makes it incredibly versatile and easy to site as they can fit inside a standard kitchen cupboard*. In addition, the Flexicom cx combi can be installed with volt free controls to enable installation without part P approval. Flexicom cx combi boilers come equipped with a pre-fixing jig to make installation even easier and an upward piping kit is available as an accessory to enhance siting flexibilty.


The Flexicom cx range's impressive features include a 5 second** hot water response thanks to the pre-heat facilty, quiet operation and temperature stability. On-board diagnostics provide superior serviceability and Glowworm's sophisticated 'Continua' electronics mean that our boilers will continue to work where others might fail because of system faults. Frost protection is fitted as standard.


The Flexicom cx combi range has acheived the highest energy efficiency rating possible and has also gained top marks for low emissions. All Flexicom cx boilers are Sedbuk 'A' and have acheived a NOx 5 rating - the best possible.
