UNDERSTANDING AND USING A DEHUMIDIFIER
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.
Does the Zeolite need replacing?
No the Zeolite is regenerated within the dehumidifier and will last for many years without the need for
replacement.
Are they expensive to run?
A compressor based dehumidifier costs about 2-3p an hour to run, a desiccant slightly more, although it
does dry the air faster and is therefore on for less time. 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 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
about it.
Should I turn the dehumidifier on for just a few hours a day?
No just let the dehumidifier’s humidistat decide when to dehumidify and when to run in fan only mode.
Will they help with allergies?
A dehumidifier will reduce the relative humidity in the house, which will prevent dust mites and other pests
from breeding and mould from growing and spreading. In this way a dehumidifier can help with allergies.
