How to Install a Vented Tumble Drier

1- How to Install a Vented Tumble Drier - Intro


A condenser tumble drier is easy to install. Because you do not need a hole in the wall of your house. However with a vented tumble drier you need a pipe or duct that takes the warm moist air out of the tumble drier, and blows it outside.

2 -How to Install a Vented Tumble Drier - What Tools will You Need?


A professional would use a large diamond core bit, to make a perfect round hole. However this tool is not really worth buying for 1 job. Although they are about £20 on Ebay so not too bad.

Basic - Hammer and Masonry Chisel (It is be harder to do a neat job without a drill)

Intermediate - Drill with 120mm long masonry bit & Hammer and Chisel

Well Equipped - SDS Drill with chisel function

Pro - Diamond or Tungsten Core Bit

You will also need a tape measure, a marker pen and a vacuum cleaner is ideal for tidy up.

3 -How to Install a Vented Tumble Drier - What Materials?

A vent kit may be you cheapest option, and will likley come with instructions, so that could be a good bet if you are doing this for the first time, or not a keen DIYer.

If you are short of cash or need to get your drier up and running quickly, you could make the hole and pull the flexible duct through that is supplied with the direr, as a short term solution. Just make sure you allow the duct to hang downwards externally, so water will not run in.

You can also use a peice of 100mm waste pipe, and and a vent cover externally. This is what I used.

4 -How to Install a Vented Tumble Drier - Where to Make Your Hole?


Most tumble driers designed for domestic use will have a 100mm vent duct. Ideally you do not want you vent pipe to exit the wall any lower than 1 meter, to prevent rodents using it as a door. Realistically you will be limited to the the height of your kitchen worktop which is usually about 90cm. In short keep the vent hole a high as possible.

In the example shown below the drier is installed in a cupboard (door must be left open when in use) and the vent exits more than 1 meter above external ground level.

Important: The rigid duct should slop down hill towards the outside of the property. Otherwise the rain will run through the pipe in to you kitchen. Also condensation.

5 - How to Install a Vented Tumble Drier - Making the Hole 

A vent kit may be you cheapest option, and will likley come with instructions, so that could be a good bet if you are doing this for the first time, or not a keen DIYer.

It is better to start from inside, but you will need to have a think about where you hole will emerge on the outside of the house. Are there an pipes or cables in the wall? Is there a meter box (!) or similar close to where you hole will emerge?

Take a piece of you rigid ducting or in my case 100m waste pipe, and us it as a stencil, position the hole as discussed in section 5.

A - Draw Around your Chosen Ducting

Next take your drill and make a series of hole around the line the you have just drawn.

B - Drill A Series of Holes & Chisel Out

Now you will need to chisel out the bit of the wall you have made you holes around, it is better to chisel because it make less dust. When you have finished chiselling you should have the following. .


C - Remove Insulation
Once you have chiselled out your hole, your will likley see the insulation in the wall cavity, this can look like wool, polystyrene or it could be foil coated.

If it is wooly (as pictured) poke it out of the way. If polystyrene or foil backed foam, you will need to cut a circular piece. I did this from outside. I like working outside!


D - Check Holes Line Up

When you are looking through the hole, there is likley to be a strong draft blowing dust etc.through it. It will slow you down if you have any eye full of fibreglass so don't get too close. 

E - Install Ducting
Next tap through you rigid duct. It may not go through first time, you may nee to get the old hammer and chisel out again to remove extra bits of masonry before it will slide through. When it is flush / parallel with the wall on in the inside, mark the pipe flush with the wall on the outside, and then slide it out a bit to cut with a saw. 

The rigid duct is now installed, first go inside and slide you tumble drier in to position, you can then reach through the pipe from the outside and pull the flexible duct in to your rigid duct. Then install the vent extract external cover.

F - Install External Vent Cover

  2. Most people will not have a diamond tip core cutter. You can do it without one and reasonably quickly too. It is not worth buying one to use it just once.
