FAQs
What kind of Appliance is it?
This appliance is a A rated high efficiency condensing combi boiler. This means it heats water when you draw a tap. It doesn't need a water storage tank or a cylinder because the boiler is connected directly to the water mains, heating water as its needed.
When was the boiler manufactured?
This boiler was first manufactured in 2009 and is currently in production. It is a Natural Gas only, Condensing and wall mounted boiler.
Is there a clock or roomstat available?
The Glow-worm Flexicom CX is compatible with a broad range of third-party roomstats and clocks. It is also compatible with our advanced eBUS connected controls such as the MiGo. For more information on roomstats you can contact an approved installer by clicking here. Full instructions on how to operate are available in the user manual:
How do I use the controls?
How do I top up the water pressure?
The boiler should read 1 - 1.5 bar of pressure when the central heating is cold. If this drops below too low, for example 0.5, this normally means water has been lost from the Central heating heating system and the filling loop is used to replace this water. When the central heating is on, the pressure may increase on the boiler, however the pressure generally must not increase by more than 1 bar. If this is the case it could indicate an internal component of the boiler called an Expansion Vessel may need pressurising. A service engineer will need to be contacted in this case.
This appliance comes with an integrated filling loop. Please see the image below:
The Two Filling loop taps Must be Rotated 90 Degrees to the fill the heating system to a pressure of 1.0 bar.
Close the filling taps once this pressure has been achieved.
If the system needs constantly topping up with water, this may indicate a fault. Please contact your installer.
My boiler has a fault and I need some help?
Your boiler should work reliably for a number of years if it is serviced annually, however occasionally faults can occur. In a lot of cases faults can be temporary and if the boiler is reset it will start working again.
