Benefits of Rear Reversing Type Flue Outlets

There are huge benefits of the rear reversing flue outlet on stoves to the majority of people wishing to install wood burning / multi fuel stoves.

Properties built from 1966 onwards generally have clay or concrete block system liners within the chimney. Almost all have been (or should be) constructed in this manner if built after 1966.



The vast majority of entries to these block system liners start right at the back wall of the fireplace opening, which makes them awkward to connect to a flue from most stoves.






If it starts a reasonable height up, it may be possible to fit a pair of bends to create an offset to kick the flue pipe backwards and reach the opening. Bends are expensive though, so fitting these will increase installation costs.




The other option is to fit an equally expensive tee piece and soot box and use the rear outlet from the stove - running the flue pipe vertically behind the unit. The downside of doing this (apart from cost) is the distance that installation of these parts will push the stove forward from the rear wall. Typically, there is approx 9" / 220mm from the back of a fitted 6" / 150mm tee piece to the back of a stove body. In the vast majority of cases, this means that the stove is projected forwards by such a great amount that much of it will have to sit forward of the opening on the hearth.



Using a stove with a rear reversing type flue outlet and fluing from the top means that the flue pipe means that the flue pipe can (if required) sit right against non combustable walling inside a fireplace opening. It will also maintain the required minimum distance from the body of the stove to the wall when doing so.

This can therefore save significant cost in parts, makes fitting easier and looks more aesthetically pleasing.


It is also possible to flue from the rear with these outlets (just as you can with a normal stove) as they are reversible. Simply remove and turn it round so it points in the other direction.



Unfortunately, my computer drawing skills aren't up to much - but my side on line drawing should give you the general idea.





We have a small selection of stove models to choose from with this type of outlet.

These include : Ladybird 6kw, Eltham 6kw, Fogo 8kw, Fogo 11kw, Elite 12kw, Modeno 14kw, Ambassador 16kw, Runnymede 16kw, Windsor 16kw


These can all be found on our website at http://www.naturalheating.co.uk/ and are available to view at both our depots - Hamilton / Scotland and Attleborough / Norfolk.
