We have a large open fireplace with a cast iron fire basket, but we only
burn logs so I'm considering whether to remove the basket so we can let
a layer of ash build up on the fire brick base and burn on that. Any
comments from those who burn logs in open fires?

that works. Stuff is easier to burn in a basket due to airflow but it's not a necessity.

So long as you restrict the supply of air from underneath, it won't make
any difference. I used to put a layer of cooking foil in the bottom
of the fire basket to stop the ash from leaking out when we burned logs
in an open fire in our last house.
I guess that's what I was wondering - I believe a supply of air from
underneath is needed for coal but not for wood, but does having it cause
the wood to burn more quickly?

But, TBH, I'd put in a log-burning stove. Since we moved and acquired
one (well, two, actually), I'd never go back to an open fire. Our wood
consumption fell about 90% ...


We've got wood burners in two other rooms, but this is a "feechur"
fireplace so I'm told it's not to be converted.

Do you find the wood burns more slowly without the basket?

if the flue is designed to run with a basket, ou may get smoke escaping
of you lower theh combustion area


I have seen pubs ho have done this raise the thing back with a layer of

Its not a question of draw - its a question of aerodynamics.

I had to reserach all this totally when my builders made a cockup of
making an open fireplace.

In generat the rule of thuimb is that te aperture the place where the
air comes in ABOVE the fire - should be no larger than 3, or at worst 4
times the area of te flue at a reasonably local point.

That makes the inflow speed fast enough to pull the smoke up the chimney
not wander around the room.

I had to fit smoke hoods to achieve this

Sigh. Did you READ what I said?

IF the fireplace and chimney are designed correctly, there is no need
for a smoke hood.

However if you lower the fire bed you may end up needing one IF the
resultant effective aperture is more than 4 times the area of the flue.

You also need a decent airflow into the room to replace that going up
the chimney. In our case we have to have the trickle vents over the
windows open and the sitting-room door open, otherwise the chimney
smokes. But it must be true to some extent for any open fi you have
to replace the air going up the chimney. Our 'fireplace' is quite
large, with the basket sitting in the recess. The aperture is 30x23
in. = 660 sq.in. and the flue itself is 12x12 in= 144 sq.in. so the
aperture area is 4.6x the flue area. That figure would be a bit less
if you take the aperture area above the fire itself. I don't think it
was 'designed'!

Well yes and no, People learned by trial and errior how to make fires
that didn't smoke.

By te late victoirian era the formula was a well known rule of thumb.

Post war, the art seems to have been lost and in any case I think that
open fires are no longer allowed to be constructed.

I would strongly consider fitting a permanent air vent in such a situation.

I used ones in the actual hearths. Easy to cover over when fire not in
use and no foot level draughts..
