living with your motor home
Propane appliances – When Propane is
burned, carbon dioxide, nitrogen and water
are given off into the air . For every 1000
cubic feet of Propane burned, nearly 88
pounds of water is released into the air .
Humidifiers – Humidifiers are designed
to put moisture into dry air – up to two
pounds per hour . So in a 24-hour period,
an uncontrolled humidifier can put almost
50 pounds of water into the air .
House plants and aquariums – Plants give
off almost as much water as you put on
them . Open aquariums permit higher rates
of evaporation than closed types .
People and animals – A large source of
water in the RV is the inhabitants them-
selves . A family of four can put up to
12 pounds of water into the air per day
through breathing and perspiration .
As you can see, just the normal course of
living adds a great deal of water to the air .
Q. – What will all this water do to my rv?
a. – The least it will do is fog your windows . If
it is really cold outside, frost or even clear
ice could form on the inside of the glass .
Excessive moisture in the air could show
up as water running down or dripping off
walls, ceilings or fixtures. It may look like
your roof or windows are leaking . This
water may stain woodwork, carpeting,
ceiling panels or even furniture .
But the most damage is caused by water
you can't even see . Water will penetrate
almost any material – except glass and
metals . Water vapor in the air always
wants to move toward dry air . Scientists
call this "vapor pressure " action . It will go
through walls, floor covering , plywood,
paint – just about anything . The water that
gets trapped in these materials can cause
warping, mildew, paint failure and rotting .
The damage caused by excessive humidity
can be invisible , and worse, expensive to
06-8
fix. Please remember that this damage is
not covered under the warranty .
Q. – What can i do to reduce or eliminate
condensation problems in my rv?
a. – The two most important things are:
Reduce moisture released into
the air and increase ventilation
To reduce moisture released inside the
RV:
1 . Run the vent fan when cooking and the
bath vent fan (or open the bath vent)
when bathing .
2 . Avoid making steam from excessive
boiling or use of hot water .
3 . Remove water or snow from shoes
before entering to avoid soaking the car-
pet .
4 . Avoid drying clothes inside (except in
the dryer, if equipped) . The water dry-
ing out of the clothes goes into the air .
5 . Vent appliances to the outside . Your
clothes dryer should always be vented
according to the dryer manufacturer's
installation instructions . (Some dryers
are designed to be ventless and do not
require a vent to the outdoors .) Check
the vents periodically to be sure they are
not blocked .
6 . If you operate or use vaporizing inhal-
ers, or similar devices, always provide
adequate ventilation .
