Condensation
Condensation occurs when warm moist air
meets a cold surface. The risk of condensation
therefore depends upon how moist the air is
and how cold the internal surfaces of the
vehicle are. Condensation is normally more
noticeable during the winter months as the
motorhome is cold and because skylights,
windows and doors are opened less meaning
that the moist internal air cannot escape.
How to try to minimise the likelihood of
condensation occurring
To try to minimise the risk of condensation
occurring it is important to try to maintain some
level of ventilation. Your vehicle complies with
EN721:1988 which states the minimum
requirements for high and low level ventilation,
it is very important that these are not blocked
or reduced in any way.
Try to provide reasonable heating
If possible use the electric element of the space
heater when washing, cooking or drying damp
clothes, particularly if the windows show signs
of misting up.
Try to make sure all areas are at least partially
heated, condensation most often occurs in
unheated areas.
To prevent condensation the heat has to keep
the room surfaces reasonably warm.
It can take a long time for a cold motorhome to
warm up so it is better to have a small amount
of heat for a long period rather than a lot of
heat for a short time.
A motorhome that has been left unoccupied for
long periods of time can become very cold.
Whenever possible it is best to put the heating
on at a low level before setting off on a journey
in the winter to pre heat the vehicle.
Even in a well insulated motorhome with
correct ventilation it is likely during cold
weather if the temperature is less than 10˚c
that condensation will occur. Ideally the
temperature should be kept at about 20˚c
although this is not always possible.
