|Central Humidifiers for Hot Water Radiator
|If you need a way to add moisture to your
house without than having to routinely refill
and clean a portable humidifier, you should
consider installing a central humidifying
system. If your heating system uses hot water
radiators, a central humidifying system will
be independent of the heating system (unlike
homes with forced air heating systems). This
article discusses systems for homes that
have hot water radiator systems.
Central humidifiers work by causing dry air
to evaporate a stream of water that has been
drawn from the house’s ordinary water system,
much like your refrigerator taps into the
water system to feed water to its ice maker.
A fan in the humidifying unit blows dry air
past the incoming water so that it picks
up moisture on the way to being released
into the house. Usually, the humidifier does
not evaporate all of the water that flows
into the unit, so some arrangement has to
be made to drain away the excess water. Although
excess water usage is wasteful, an extra
flow of water can be used to carry away mineral
deposits and potential mold accumulations,
thus helping to keep the humidifier clean.
A central humidifier for a hot water radiator
system relies on either finding a central
location through from which the house's air
naturally circulates because of convection
or installing ductwork; otherwise, the unit
merely humidifiers one area of the house.
The selected location must accommodates both
a connection to the incoming water and access
to a drain.
As with all humidifying systems, the humidity
level is controlled by a humidistat, which
turns the humidifier on and off an internal
fan according to the humidity in the air.
