Glow-worm have now introduced a new horizontal telescopic flue as an improvement to the High Efficiency Flue System. The new flue has an aesthetically improved terminal, better UV stability and is fully interchangeable with existing bends and extensions. There is also a non-telescopic version available for single brick walls, an internal and external collar and is suitable for use with the new Plume Management Kit.
There is no change in dimensions except for the terminal length which has been reduced from 145mm to 87mm. There is also no compatibility issues with old boilers.
There are no changes to existing bends and extensions which remain the same colour (RAL 9016) and are fully compatible with the new flue.
