can I get the cheapest dehumidifier ?"
dehumidifier removes moisture from the air by passing the moist air over a cold
dehumidifying coil. The moisture condenses out of the air on this coil and then
drains from the coil into a bucket.

A dehumidifier reduces the relative humidity of the surrounding
air two ways. The removal of moisture from the air ( as described above ) reduces
its humidity. The relative humidity of the air is further reduced by heating
as the air is discharged over the condenser and out the front. The air is
actually heated several degrees in this process. It is normal for the surrounding
air to slightly increase in temperature as the dehumidifier operates. This
heating effect further reduces the relative humidity of the surrounding air.

Below are answers to the sorts of questions
that we are often asked by people looking to buy their first desiccant dehumidifier .
We have divided this section into two, desiccant dehumidifier s for the home and
desiccant dehumidifier s for unheated or colder areas (i.e. storage, garages, workshops,
boats, caravans, holiday homes, conservatories etc.)
As the warm air circulating
ducts passes over the evaporator coil, it is quickly cooled and can no longer
hold as much moisture as it did at a higher temperature. The excess moisture condenses
on the outside of the coils and is carried away through a drain. The process is
similar to what happens when moisture condenses on the outside of a glass of ice
water on a hot, humid day. Occassionally, the drain lines may become clogged and
your system will not drain properly. This can result in a drain pan overflow,
leading to water leaks in your ceiling or walls. An annual inspection by
an experienced technician includes an inspection of your draining system. During
the inspection, the technician will treat your draining system with an algaecide
to retard the growth of algae, which can clog your system.
How does a desiccant dehumidifier work?
A desiccant 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 air is then reheated to room temperature
and blown back out of the desiccant 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?
We all produce water as we breath, 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 summers day but in
winter opening your windows will just result in you losing the heat from your
central heating and create 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 industrial dehumidifier do the whole house?
A industrial dehumidifier creates a volume of dry air
in as large a space as its fan can effect.
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 industrial dehumidifier will prevent condensation
from appearing around the whole house.
What about the black spots of mould on my window and bathroom
Mould occurs around 68% 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 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 at for example the bottom of the stairs will cure the
problem in the whole house.
Are they expensive to run?
A dehumidifier costs about 2-3p an hour to
run. You should take into consideration the
fact that the commercial 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 commercial dehumidifier .
What is the humidistat?
Just as you have a thermostat that you set
on your central heating you have a humidistat on your commercial dehumidifier . This will allow the portable dehumidifier to turn
off and on as required without you having to worry about it.
Should I turn the portable dehumidifier on for just a
few hours a day?
No just let the portable dehumidifier decide when
to come on using its humidistat.
Will they help with allergies?
A best dehumidifier will reduce the relative humidity
in the house, which will prevent dust mites and other pests from breeding. In this way a best dehumidifier can help with
allergies. For more information

Why do unheated areas get separated out?
A best dehumidifier that can be found in your
local high street store is designed for use in your home, which is nice and
warm. In a garage, store, workshop, boat, caravan,
holiday home or a conservatory the temperature will drop a lot lower.
Since a portable dehumidifier works by reducing the temperature internally it
can easily reduce down to freezing even if the ambient temperature is 10°C.
What you do not want is for your portable dehumidifier to form a block of ice
or for you to find a puddle on the floor.
What happens when the temperature in the room drops down
Most portable dehumidifier s designed for use in the
home will just stop working and turn themselves off.
Others will try to work and might well suffer from a build up of ice. Those with a defrost system are likely
to only extract a tiny amount of water.
What is the correct type of commercial dehumidifier to use in these
You need a machine with a function called
hot gas defrost. If the commercial dehumidifier
does not have this then do not buy it.
How does Hot Gas defrost work?
Hot gas defrost works by reversing the coils
and using the heat from the hot side of the coils to melt the ice to water. When this is done the heat is returned
to the front of the machine to warm the air before it is blown back out.
So what temperature will a hot gas defrost system
work down to?
