I need to buy a vent for my kiln. Could you give me your opinions as to
whether hood venting above or venting from below is better? Looks like
there are advantages to both....
Thanks. Sharon

Venting from below takes those hot spots from the top. I think it makes the
firing more even. I have used both. I extended the exit ducting along the
wall through my studio. The heat radiating from it warms the place on chilly
mornings.

I have an Envirovent and absolutely love it. My electric kiln is in my
basement studio and I can't smell any odors at all when it's firing. The
temperature seems pretty even across the kiln, as well.

I have a "below" vent. One doen't have to do much but roll your foot on the
switch to turn it on. The most amazing thing was putting a hole all the way
through the wall. I was in a state of wonder to see the light from outside!
I had to buy the dryer vent and tubing seperate but it was pretty cheap. The
vent requires three holes in lid and same in bottom, very easy to drill. It
makes about as much noise as any fan does. Good luck, susan de Wit

Venting from below would be a better choice in my opinion. With a kiln vent bel
out of the kiln from the bottom before the fumes enter the room, this facilitate
kiln. A hood vent on the other hand removes only those fumes that have already
of a kiln vent from below are a decreased cooling time without even opening the
information on kiln vents, just post a message and I'll send you some informatio

Personally, I have been very happy with the vent systems which draw from the
bottom or lower side of the kiln. I know that there are those on this list
who seem pleased withe Vent-A-Kiln system, which is basically a large hood
on a pully system so that it winches up and down to get out of the way when
you are loading and unloading the kiln. I do not think this system is very
effective at all, expecially in a space where there might be any cross
draft. During the water-smoking period of a bisque fire, the greatest
release of toxic gases occurs when the exterior of the kiln is not that hot,
and therefore the convection currents on the outside of the kiln are
minimal. A hood system relies absolutely on convection currents to carry
the fumes upwards to the hood. Even in a room with no crossdrafts it is
doubtful whether this system does a very good job of venting sulfur dioxide
and other gases, and any crossdraftwill completely disrupt its function.
I like the Bailey system. It's simple to install, very effective, and will
vent two kilns. I see that they now also offer a less expensive system
which only vents one kiln. We installed a Bailey system to vent two
electric kilns at U-Mass. The kilns were located in a classroom with people
present during firings, and there was never any problem with fumes as long
as the Bailey system was operating.

We use the venting that the kiln sits on and both kilns don't have the vent
in use because a slight vibration is causing the cone to eventually come out
of the kiln sitter and shutting down the kiln before temperature is reached.
We have tried cleaning the fan blades, leveling the kiln, but this only
helps for a short time. It is a pain to remove the kiln in order to clean
the fan. The next vent we buy will be mounted external to the kiln.

I agree with Char having also used both. With a down draft you never have
a cold bottom.
