How does a dehumidifier work?
There are four types of dehumidifier sold to the domestic market in the UK - Compressor (this
.c
o.
dehumidifier), desiccant, peltier and silica gel.
A compressor based dehumidifier draws the air in from the room over a filter and passes it over some cold
coils similar to the coils on a fridge. As the coils are cold, water condenses and drips into a bucket. The
bs
air is then reheated to room temperature and blown back out of the dehumidifier.
Why does water appear on my windows/cupboards/walls?
It is a basic law of physics that if the surface is cold enough and if there is enough water vapour in the air
then it will condense. This means in the case of windows whether they are double-glazed or not that if the
windows are cold enough and there is enough moisture in the air then condensation will occur.
Where does this water come from?
ul
We all produce water by drying clothes indoors, the boiling of vegetables, showering, rain, calor gas
heating and making cups of tea all produces moisture. It is just an on-going process that never stops.
Can I just get rid of it by opening my windows?
This is fine on a nice summer’s day but in winter opening your windows will just result in you losing the
yb
heat from your central heating and creating draughts. This is a waste of money and if it is raining will just
let more moisture in. You might as well just throw fivers out of the window.
Will a dehumidifier do the whole house?
A dehumidifier creates a volume of dry air in as large a space as its fan can effect (this dehumidifier can
control up to a large 5 bedroom house). After that it will be helped by the fact that damp air will always
migrate to dry places. As long as you leave all of the internal doors open a correctly sized dehumidifier
rg
will prevent condensation and mould from appearing around the whole house.
What about the black spots of mould on my window and bathroom sealant?
Mould occurs around 68% relative humidity, condensation occurs at 100%. As you can see from this you
can have mould but still have clear windows. A dehumidifier will prevent the mould from getting any
ne
worse and once you have cleaned the mould away, it will stop it from coming back.
Do I put it in the worst room?
You can if you like put it in the main problem area to start with and then move it somewhere more
convenient when you feel that the problem is under control. If it is just condensation on the windows that
you are worried about a dehumidifier in a central position, for example the bottom of the stairs will cure the
problem in the whole house.

UNDERSTANDING AND USING A DEHUMIDIFIER
uk
Are they expensive to run?
A compressor based dehumidifier costs about 2-3p(ish) an hour to run depending on your electricity tariff.
.c
o.
You should take into consideration the fact that the dehumidifier will not run all the time, as it will be
controlled via its humidistat. Secondly it is very expensive to heat a damp house and you will see a
bs
reduction in your central heating bill when you start to use your dehumidifier.
What is the humidistat?
Just as you have a thermostat that you set on your central heating you have a humidistat on your
dehumidifier. This will allow the dehumidifier to turn off and on as required without you having to worry
ul
about it.
Should I turn the dehumidifier on for just a few hours a day?
yb
No just let the dehumidifier’s humidistat decide when to come on.
Will they help with allergies?
A dehumidifier will reduce the relative humidity in the house, which will prevent dust mites and other pests
ne
rg
from breeding. In this way a dehumidifier can help with allergies.

DEHUMIDIFIER SETUP AND USE
For best results position the dehumidifier somewhere central like a landing or a hallway. As long as the internal doors
are open the moisture will migrate naturally towards the dehumidifier to be processed.
To dry washing it is best to put the dehumidifier into a small room with some heating on. Close the door and windows

. Hang the clothes so that they are not touching each other and so
that air can circulate between the clothes. Ensure that water does not drip onto the dehumidifier.


Amount of water collected
When you first use your dehumidifier it will work harder to reduce the room humidity down to 60%rh (in “Normal” mode
). This is the time when it will produce the most water and need emptying most frequently. As the room
becomes dryer the dehumidifier collects less water and takes longer to fill the tank, this is perfectly normal. When the
target relative humidity has been reached the dehumidifier will stop collecting water, again this is normal.
