For the Homeowner:
How Your Humidifier Works
Your White-Rodgers Comfort-
Plus Steam Humidifier sup-
plies moist air to your home
much the same way as
outdoor air is humidified. On
a warm summer day, the
sun’s heat evaporates water
from puddles, streams, rivers,
oceans, etc., turning it into
vapor (
humidity
). The amount
of water vapor that rises into the air is determined by the amount of time the
water is exposed to the heat source.
If you were to look inside your humidifier’s reservoir, you would see an
immersed, tubular heater and two floats. When your home is too dry, the
humidistat (humidity control device) installed with your system activates the
humidifier heater. A built-in thermostat senses the water temperature and,
when the water is hot enough, turns on a relay to activate the blower on your
furnace. The blower, independent of your home’s heating system, disperses
humidified air throughout the house. In other words, the heat necessary for
evaporation is supplied by the humidifier itself, rather than by your furnace.
Once the selected level of humidity is reached, the humidifier heater turns
off automatically. However, the furnace blower continues to replenish the
moisture in your home until the water in the humidifier’s reservoir is cooled
and ceases to produce steam. All this takes place without disrupting your
heating system’s normal operation. When the indoor humidity drops below
the desired level, the process begins again.
As water is evaporated from the humidifier reservoir and replaced by fresh
water, the larger of the two float valves prevents overflow by shutting off the
water at the designated level. The smaller float acts as an additional safety
device, automatically shutting off the humidifier heater if, for any reason, the
water level drops below the heating element.
Because water evaporated from the humidifier leaves behind all its impuri
-
ties (calcium, iron, lime, bacteria, etc.), the resulting humidification doesn’t
pollute your indoor air. Instead, your home is freer from these contaminants,
creating a healthier, more comfortable environment for you and your family.
