Tumble Dryer venting
About to buy an AEG vented tumble dryer and am considering the options
for vertical positioning of the vent outlet through the nearby outside wall. Am using the Screwfix tumble dryer vent kit. Two options, low down (30cm) or high up (2.5m) on the wall. The outside of the wall is onto the street, so I'm slightly concerned about the possiblilty of small animals (squirrels etc.) getting in (despite the vent louvres) or kids messing with it if it is low down. On the other hand, if it is high up then it looks more conspicuous (not really a problem), but more seriously is there a potential problem with condensation running back down the pipe? I'd have thought that so long as the dryer runs it's cool phase at the end to hopefully evaporate any condensation and also making sure that the wall vent is installed with a slight downward slope to the outside then there would be no problem. If I went for the 'high' option then the total run length would be around 3.5m (as the vent outlet on the dryer is right at the bottom). I'm aware that this is slightly beyond the recommended maximum run length of most manufacturers (2.4m), but believe that this maximum is specified due to the friction against the air of the corrugated venting hose causing the dryer efficiency to drop off. I could run instead with smooth plastic pipe which should alleviate this if necessary. Any thoughts, specifically about the condensation issue? Cheers. |

I don't have direct experience, but several people have posted about condensation in long vertical runs. Apparently as the warm, wet air hits cold air at the top, you get so much condensation that some of it can run back down.

Have you considered a condensing drier ;-) -- Grunff Hi I have a tumble drier that was vented up through a window and it failed after 18 months. It was the over heat protector fuse. The repairman said that it was caused by having the vent too high and as the window faced west and it was very windy when it failed that was most likely the cause of failure. I now have it venting straight through the wall and the clothes actually dry 10 minutes quicker, or so my wife says. Ron |
Have you considered a condensing drier ;-)
Buy a condensor box, or make one. The outlet vent goes into a "cold" box, so that it condenses. Could be little more than a square box. Would work better if surrounded by cold water, like a tin within a tin. Simon. |

Have you considered a condensing one? I *love* our Miele condensing drier - it's magic. Yes, I've been toying between the two. Initially I'd plumped for a condenser, but have since been reconsidering vented for the following reasons. Condensers are... More expensive to buy (about 350 quid as opposed to 270 for the vented model I'm considering) Not (quite) as quick at drying. More expensive (a bit) to run Need to empty the water frequently (though I could get the drain kit for the model I considered) Need to clean out the condenser module sometimes. Noisier in operation But the advantage is they are 'fit and forget' (optional drain kit notwithstanding) Whatever I buy will be going in the garage, so any increase in ambient temeprature and /or humidity is not a problem. My only direct experience of tumble dryers in the past has been 2 washer/dryers (useless at drying, I know!) and my mum's 25 year old creaky 'Servis' model. I imagine that efficiency has moved on since then. I'd appreciate any feedback from anyone about how much slower or noisier (if at all) condensers are. I'm still willing to change my mind. The screwfix vent kit was only a tenner wasted if I don't use it! Cheers. |

We have a condenser dryer and have been very very happy with it. Mike |

The screwfix vent kit was only a tenner wasted if I don't use it! Our condernser is not at all noisy (certainly no noisier than vented models I've seen at friends' houses). It does a full load in 45-60 mins. As for the slightly higher running costs, we have it installed in the unheated utility room, so for 9 months of the year the heat it dumps into the room is very welcome. I have it draining to the nearby sink trap, so no emptying. I would buy another without hesitation. -- Grunff |

The outside of the wall is onto the street I would not appreciate a faceful (shinfull depending on height) of tumble dryer fumes so if your vent MUST be to a public street does it not have to be a certain height? If the dryer can be vented onto private ground, animal/insect interest is not a problem with the proper one way flaps (only time these flaps are open hot/moist air is actually coming out ). Condensation doesn't seem to be a problem with our set-up however the prevailing wind is not into the vent and ours (vents into the back garden) is only 10~20cm above the outlet on the machine. Thinking out loud :- Will a small s bend in the hose not allow any condensate to gather and not travel back to the machine. This condensate will only gather over the last few "puffs" of the tumble drier and these "puffs" should be of virtually ambient moistness anyway so will condensate in the evacuation tube be a problem. -- This post contains no hidden meanings, no implications and certainly no hidden agendas so it should be taken at face value.

So why are condensers more expensive to run - surely they recycle some of the heat into the incoming air via the condenser, which must be cooled by something? -- Spamtrap in use To email replace 127.0.0.1 with blueyonder dot co dot uk |

We don't have a drain kit for ours, but I don't find emptying the water a big deal. Paul Mike |

Academic now anyway, since I've reverted to the original condenser plan and also installed the appropriate drain-out plumbing. Thanks for all the comments anyway! |

You "drown"/suffocate in a Carbon Dioxide atmosphere.

I suspect you're either getting confused between carbon monoxide (lighter than air, toxic) and carbon dioxide (heavier than air, non- toxic), or half-remembering the difference between town gas (contains carbon monoxide - can poison you but is lighter than air so will disperse more readily) and natural gas (basically non-toxic but heavier than air and can drown you). |

I doubt it. Many schoolkids know and disseminate the line that CO bonds strongly to haemoglobin. This is seen as reversible. (Glod save us from amateur scientists!) Knowledge of its action at cellular level needs a deeper knowledge of biochemistry etc. I think I was only thus enlightened relatively recently. I was amused that your post was essentially so similar to mine; we must be singing from the same crib sheet ;-) -- Helen D. Vecht: Edgware. |
