Bypass Humidifier How Does It Work

The bypass humidifier is connected to the return of your furnace or air handler. It does not have a motor of its own and instead relies on the blower motor of the furnace to push warm air through it. The warm air is then pushed through the water panel that is within the humidifier and absorbs moisture from it.

Is a bypass humidifier good?

Bypass humidifiers are less efficient because the moist air has to pass through the furnace fans for distribution, which results in humidity loss. Moreover, the units use more water to prevent mineral buildup in the water panel.

Why does humidifier need bypass?

According to air conditioning installation experts, this type of humidifier produces increased water evaporation, which results in an additional gallon of moisture. Because of the additional ductwork that’s required, bypass humidifiers take up more space compared to fan-powered units that don’t need as much room.

The solenoid is an electrically actuated valve that allows water to flow to the humidifier and is controlled by the humidistat—a sensor that operates like a temperature thermostat but is designed to sense humidity. The humidistat will only send voltage to the solenoid when the furnace is running and moving air.

What is a power humidifier?

Definition: A power humidifier is essentially the same as a bypass humidifier at the basic component level in addition to having a “power” fan. The power humidifier fan forces air across the water panel to produce more humidity than a bypass humidifier.

Can a power humidifier be installed on the return?

Aprilaire power humidifiers are design to be installed on the hot air supply plenum. If however, there is no space available due to the HVAC air conditioning coil or the layout of the mechanical room, the Aprilaire power humidifier can be installed on the cold air return duct.

How do you humidify a whole house?
