Explanation of A and B Options
Mounting the humidifier on the warm air
supply or the cold air return plenum does
not alter humidifier performance. In either
location, air will flow from the warm air to the
cold air side due to the positive and negative
pressures of the heating system.
Humidity produced by a bypass flow-thru
humidifier is dispersed as a pure vapor (i.e., a
gas), not as a liquid. The moisture will remain
in the air, even when reheated. The humidity
can only be depleted by escaping to the
outside or by condensing on a cold surface.
Because all surfaces in the furnace/humidifier
system are warm, condensation is unlikely.
