The Glow-Worm 30hx Flexicom 30kw heat only open vet conventional condensing gas boiler is a boiler that can suit many varied installation needs.  Ideal for most homes, from apartments to 4 bedroom detached, the Flexicom hx open vent boiler provides a large supply of hot water through a compact boiler, a storage cylinder (normally housed in your airing cupboard) and a cold water tank in your loft.

The Flexicom hx open vent boiler is compatible with any indirect cylinder and cold water tank so you will have no problem using it as a replacement within an existing system. Plus, the Flexicom hx is so small, it fits inside a standard kitchen cupboard* so no one need know it's there.

And because it's also the only condensing open vent boiler in the UK with a direct rear flue option, the Flexicom hx is not just neat and tidy - you can fit it almost anywhere.
