The Flexicom cx combi boiler



Our Flexicom cx combi boiler is ideal for small to medium sized homes, from apartments to 3 bed semi detached properties.

It's so small it fits inside a standard kitchen cupboard* and because the Flexicom cx is a combination boiler, there's no need for a cylinder or cold water tank either.

The Flexicom cx is the only condensing combi boiler in the UK with a direct rear flue option, so is not only neat and tidy but you can fit it almost anywhere - particularly helpful when replacing old direct rear flue boilers.

The Flexicom cx combi boiler is now also available with the option of a 'glide down' plug-in timer. One simple push and the clock glides into position. Set the time to your requirements and another gentle push hides the clock from view in the base of the boiler.

If space is a premium and you want the most efficient solution, then look no further than a Glow-worm Flexicom cx.
