What we think of the Glow Worm Flexicom cx 

Glow-worm’s Flexicom CX combi boiler is powerful, economic and ergonomic. Guaranteed to save you money and space, this condensing boiler is easy to use and flexible to install; making it the ideal choice for smaller properties.

This is a boiler, which has been designed to happily sit inside a kitchen cupboard without taking up a lot of room. In short, if you are keen to get a powerful boiler that doesn’t grab a lot of space, then this range could be for you.

The range is nicely balanced with an entry rating of 24kW. The two other versions means that the range can cope with anything from a flat, through to a small house. As it’s a combination boiler, it also means that more space is saved, because you don’t need all the incumbents associated with a boiler that uses a hot storage water tank. This means that hot water is produced on demand.

It will need some space around the casing when its fitted into the cupboard and has an average weight of around 36kg. It’s well-equipped with some decent controls and it can cope with most things asked of it.

    We have moved to a Housing Association two bedroom flat (groundfloor) very happy and am presuming that we have the CX 24 model. However this condensing boiler does take a time to reach the standard output heat to hot water of 55degree C at a much greater time than the 5 seconds as stated in your advert. Could there be a fault in the thermostat or equivalent and should we make comment of this to Blue Flame who manage this gas boiler?????
