Hi all,
Tumbler now in garage but at the back of it and I’m wondering which way to the vent it. the new house has about 1.5 feet of solid stone walls so I’m not particularly keen to core drill it :0).
There is a hole already at ceiling height above the tumbler which ahs a decent size fan in it to extract the fumes when I put my van away . I was thinking of making some sort of boxing to run the vent into and refit the extractoron the end of the boxing.
However the easiest route would be straight down the side of the garage and out that way. I’d have to find some sort of flat plastic tubing for the final bit as i only have a 4″ piece of wooden upright to run it through.
I digress , my question is how long a run can i get aaway with on the ducting? The garage is 5m long.Cheers

Re: Maximum length of ducting?
Ok thnx ,
I might give it a go anyway as the ducting is pretty cheap anyway , failing that I’ll have to modify the existing outlet :0(Dames
Re: Maximum length of ducting?
the reason for short ducting is, if its too long the resitance along its length is more than the extract fan on the drier can handle, and also the steam will cool and turn to water before it reaches the outside air.

Absolutely, then you get mildew and bacteria growth indie the hose… bad smells and so on. Basically, not good.
Same thing if you get dips in the hose, the water will condense and pool in them especially in a colder environment, such a garage.

Yes , I thought that might be a prob. My thniking was to use soemthing like this
http://www.screwfix.com/p/manrose-recta … 00mm/14118
Which I’d run at around 15-20 degrees down towards the exit point hoping that most of any condensation would run out. Think i’ll just buy a couple of flexis first just to test how far the fan kicks it out to see if it would be strong enough.
Looking like its going to be a mod of some sort though to use the existing hole in the wall , thinking cap on.
Another question then , could I use a smaller diameter pipe for the last couple of feet which would share the existing hole with the extractor?
Say 45mm waste or something?

Just remember the further you go the less “push” there is and the more chance for the water vapour to condense, that’s the main reason for the normal 2.5M maximum.
Even if the air is driven by an additional fan, you still face the problem of the air cooling off and condensation forming unless you also defeat physics with your mod. 😉

If all else fails then , any recs for a condenser to go in my garage?

Re: Maximum length of ducting?
Condenser dryers don’t work in temperature extremes so they’re not suitable for use in outbuildings that aren’t heated.
Get below about 5-10?C and the vapour will condense on the inside cabinet and the clothing won’t dry. There’s loads of threads on here with people having issues with that.
If the ambient temperature rises above about 30?C you also get problems.
Vented dryers tend to be okay and more of a success in that sort of installation but you can still get issues.

Thnx K ,
Decisions to be made here then , have to have a think on the best way to attack.Cheers

Re: Maximum length of ducting?
If all else fails, you could buy a condensing unit to fit to the end of your vented dryer… They look unsightly but it would solve the problem I reckon.
Re: Maximum length of ducting?
seen water locked dryers on a few occasions
best one was a school where they had used 4″ soil pipe but had a dip in it so it filled up with water
condensing units dont work very well and wont stop all the moisure plus the fact you need to put ice in them to work properlyyou could use soil pipe to extend but make sure it has a fall to outside. dont forget in cold weather more condensation will form in the tubes and as stated keep it as short as poss to prevent problems
