Tumble dryer venting
 

Can anyone answer a few questions before I start looking/purchase one:

I need a built-in/integrated tumble dryer and need it to vent sideways. Is this possible?

If not, is there enough room behind a tumble dryer to turn the vent hose through 90 degrees where it comes out of the appliance and have it coming out sideways at the rear?

Can anyone recommend a make/model that they have or ones to avoid?

You comments would be appreciated.

I haven't had a crappy vented dryer in years. Buy a proper condensing one
and you don't need an inconvenient hose snagging and kinking. You also don't
need an ugly hole in the wall that will be in the wrong place/size for your
replacement model.

I have a Bosch 6920 integrated tumble sensor dryer. It is absolutely
brilliant. The filter works really well, it has a outlet pump and came with
the drainage kit free. Sensor drying is such a convenient cost saving
measure. No air hose is required. It collects water very well (it used to
fill the huge tray every drying cycle, even after a 1600 spin which left the
clothes feeling quite dry), with no obvious increase in humidity or
condensation in the room. It was in a different league to my previous Hoover
condensor.

Hello,

Sorry to butt in (after lurking for years) but I'm about to have an
extension built to increase the size of my kitchen and I was wondering
about the possibility of having my washing machine and tumble drier
moved into the cupboard under the stairs at the same time, to get them
out of the cooking/dining area. My current tumble drier is a venting
one, so I'd need to buy a condensor - do you think that it would be
worth doing this and would it be feasible to run it under the stairs
with a closed door to the cupboard, or would I just be storing up grief
for myself with condensation and damp building up in the middle of my
house? I'm getting a new shower room put in next to this cupboard, by
the way, so it shouldn't be difficult to run plumbing and drainage
through the wall between the two.

Cheers

Helen

Yes, although my old Hoover would have been a problem. The Bosch would
handle this. However, you will need some ventilation, as it will produce
some moisture which will cause problem if there is no way at all to get rid
of it. With the adjacent shower room, it would be very easy to ventilate
through there, as shower rooms need ventilation anyway.

I don't know what you've got planned/already existing in there, but just a
simple grille between the rooms might work if the shower extractor is good.
Alternatively, a humidistat fan to vent from the cupboard into the shower,
or best of all, a ducted system with inline centrifugal fan that can suck
from both rooms.

so it shouldn't be difficult to run plumbing and drainage through the
wall between the two.

Don't forget to choose a model with a built in pump that can drain away.
Emptying the tray of water every time is a drag.

As a simple rule of thumb, machines with the water tray at the top have the
pump and can be mains drained, although sometimes they wish to use the
opportunity to hawk an overpriced kit of parts to do so. My Bosch 6920 came
with the "kit" free, and it consisted simply of a length of hose.

The problem is that it's hard to know how much humidity a machine will
produce before you buy it. I did have a look at Which but, although it
did claim to mark the machines on humidity, they all seemed to come out
on a similar level, which makes me think that either all condensing
driers are pretty good now or the Which people didn't really measure
them all that closely. Still, I guess I have a personal recommendation
for the Bosch now!

The shower room isn't going to have a window in it, so I'm assuming the
venting is going to be pretty good... Actually, a problem just occurs
to me in that the vent will need to come out of the cupboard under the
stairs through the wall where the shower is actually going to be (i.e.,
the shower is going to take up the whole of one end of a narrow room,
with no wallspace on either side and this backs onto the cupboard
wall), so I guess it will either need to be up above head height, or
I'll need to forget it. Oh well, I guess I'll need to ask the builder
if he thinks it's going to be possible.

Thanks for your advice, though - it's much appreciated!

Yes, it is possible, at least with Miele dryers, vent both sides and rear.

Miele dryers are very good but more expensive than the average.

I agree. I was asking about tumble dryer venting about 3 weeks ago,
but in the end plumped for a condensing model due to potential
difficulties in how I'd vent it properly.

Good decision I'd say, and I'm well impressed with how well and fast
it dries the clothes.

I bought a John Lewis own brand condenser, though it is actually made
by AEG. Plumbed into drain so no resevoir to empty.

The 'drain out' kit for my John Lewis condenser dryer (actually made
by AEG and identical mechanically to their current range) sells for
the princely sum of around £30, and consists of little more than a
length of small bore tubing to my knowledge. It's actually an AEG
official part you have to buy from AEG, not John Lewis.

Fortunately the drain tube that enters the machine's reservoir
actually emerges from inside the back of the machine near the top and
connects to the reservoir on the outside. I simply took it off the
reservoir, connected another length of much cheaper small bore tubing
and extended it to my drain. How they can justify such a price for a
bit of pipe is beyond me.

so I guess it will either need to be up above head height,

Above head height is what I was thinking. Remember, modern condensing dryers
are actually quite good. You don't need a huge amount of ventilation, just
enough to clear the air eventually. Nothing like the massive amount of
ventilation required for a vented dryer.

Just opening the door for an hour or two would also work, but might not be
to your taste.

I'd actually wondered if I could get away with just fitting a vent to
the cupboard door so that the hot air could vent gradually to the
hall...

Thanks again for the info!

I have done quite a bit or research on this issue.

I have a Miele condenser dryer draining to a waste pipe, it works quite well.

It can be installed in a cupboard, as I will have it, because the moisture loss is very low.

The important thing is to provide plenty of air for the dryer to run economically and quickly.

For that, it is enough if the door to the cupboard is open and the door leads to a medium size room, ideally a large well ventilated room.

Read Which? magazine for reliability and efficiency reports. Copies in
your local library, you can read them for free & take notes. You won't
be able to take them out, and they are carefull designed not to (b&w)
photocopy.

Are modern condensers good these days? Do they dry clothes efficiently?
