The Flexicom sx system boiler

Ideal for most homes, from apartments to 4 bedroom detached, the Flexicom sx range provides a large supply of hot water through a compact boiler and a storage cylinder (normally housed in your airing cupboard) without the need for a cold water tank in your loft.

The Flexicom sx system boiler is designed to be extremely flexible. It's so small it can fit inside a standard kitchen cupboard*, it's compatible with any model of indirect cylinder and the Flexicom sx is also the only condensing system boiler in the UK with a direct rear flue option - so you can fit it almost anywhere.
