3D typical installation drawing from Schiedel. This 3D drawing forms part of our flue and chimney range and can be used with acknowledgement to Schiedel Chimney Systems Ltd. as well as a link to the original source at www.schiedel.com/uk A typical flue installation includes steel chimney pipe or mineral pipe or module components from the heat source appliance (a stove, biomass or gas appliance for example) to its termination point above the roof. Support is required for internal and external chimney systems. Schiedel specialise in wood burning appliances and flues, which are a renewable way of avoiding constant gas or electricity usage when looking at a secondary heat source. Even heat pumps are problematic with severe temperature drops, so a secondary source is always needed.
