ICID Plus Twin Wall Flue, is ideal not only for traditional stoves but also for pellet stoves, biomass appliances, mini/micro CHP and even condensing boilers capable of withstanding positive pressure.
The system is designed so that the outer case is load bearing and the inner liner is free to expand independently, therefore thermal expansion is accommodated within each and every joint of the system.
Specifically for use on open or closed wood burning stoves with continuous operating temperatures of up to 450°C.
Condensing gas and oil appliances, with continuous operating temperatures up to 200°C, short firing up to 250°C, and positive pressure up to 200Pa at the appliance outlet.
Non-combustible floor installation example.
Typical installation with a biomass boiler system.
