Determining a DFE and a LFE fire

[craig51]

Ok,

Apart from the MI's, or in the case of a DFE, being able to look right up the chimney with the fire in place, what other ways are there to tell if a fire is a DFE or LFE, if they are inset????

I find this really hard to do, yet some people can tell right away just by looking at it.

a DFE is a stand alone basket type fire, which is fully open to the atmosphere with the flames clearly visible through the coals/stones, a LFE has a back panel assembly which has flue spigot and a built in heat exchanger, (and sometimes a glass front) to deflect the heat out into the room, so i've never really had too much trouble identifying them (although my description isnt too helpful )

thanks Kirk Gas,

I agree, when its a basket style etc, its fairly easy, but i have trouble when you walk in, and there is either an inset DFE, or an inset LFE. Apart from the flue spigot being applicable to the latter, are there any other way???

Decorative Fuel(or Flame) Effect (DFE) fires are generally a free standing basket or tapered fire designed to sit in either the builders opening or a shaped fireback (cast register grate or refactory cement fireback). They are typically only 20% efficient since unrestricted excess air is drawn up the flue.

The Inset Live (or Living) Flame Effect (ILFE) fire is sealed to the builders opening. As well as heat being radiated from the fuel bed heat is also produced by convention through the heat exchanger. Excess air is limited and efficiency is significanty increased. The fire is generally flush with the wall surface, hence inset.

The Outset Live (or Living) Flame Effect (OLFE) fire is identical except it is outset from the builders opening.

THATS WHAT I WAS TRYING TO SAY

And by convection, conventionally
