How a Furnace Humidifier Works

Furnace humidifiers connect with a water source and mount to the hot air supply of your furnace, distributing moisture via system ductwork. Furnace humidifiers work in tandem with your furnace or heating unit, turning on/off based on your chosen humidistat/thermostat settings, typically when the relative humidity drops below 30-50%. When in-use, they produce moisture, infusing it with furnace-heated air.

When your system is in heat mode, simply engage your humidifier by adjusting humidistat dial settings. Turn until you hear a click to determine current humidity levels in your home, changing settings accordingly. If your heating system has a bypass damper, make sure the damper is in ‘open’ or ‘winter’ position and parallel to the duct. If you see water draining from the humidifier while your system is running, your humidifier is in operation.

Types of Humidifiers

  • Steam
    Steam humidifiers are the most efficient style and also require the least maintenance, however, this comes at a higher initial cost. They self-generate steam, boiling water on-demand, and injecting steam into the heated air from your furnace.
  • Flow-Through
    Moderately priced flow-through humidifiers are more reliable than reservoir systems and require less maintenance. They rely on water tapped into the system from an existing water pipe, which drips across a specially coated screen. The furnace blower induces evaporation while the system is running, distributing moisture through your home.
  • Reservoir
    Reservoir systems use a rotating drum of water to create moisture. They are inexpensive, but the least efficient furnace humidifier style. Because they remain full of water, they are also prone to mold issues, requiring more frequent disinfection maintenance.

A Whole House Humidifier is an Affordable Addition
