Dry air in your home can cause many problems, especially during the winter months when the furnace kicks on. It can cause issues from comfort and health problems to damage to your home. One way to help combat dry air in your home is to install a whole-house humidifier.
What is a Whole-House Humidifier?
A whole-house humidifier shouldn’t be confused with a portable humidifier. Portable humidifiers are devices that plug into the wall in individual rooms. A whole-house humidifier installs directly into your heating system’s ductwork. When your furnace cycles and heats our home, it humidifies the air with a single unit.
How They Work
The whole-house humidifier installs in the ductwork near the furnace, either on the supply or return end. It also connects directly to the home’s water supply. Inside of the humidifier is either a humidifier pad, a rotating drum or a steaming system that is used to distribute water to your home’s air. Depending on your model, and while the humidifier is running, water continuously runs down the humidifier pad, is collected by the rotating drum or is misted into the device.
The air is exposed to the water inside as it enters the ducts. The water evaporates into the air, which increases the moisture levels of the air that exits the humidifier on the other side.
While your furnace is running, a portion of the air cycles back to the humidifier and joins up with the rest of your home’s airflow. As a result, it raises the humidity level in every room.
3 Types of Whole-House Humidifiers
Here are three types of whole-house humidifiers to consider.
- Bypass Humidifiers draw air from the home’s heat ducts and pass it through a water panel. You can have them installed on either the Supply or Return of a forced handling air handling system.
- Fan-Powered Humidifiers work in the same way as a bypass, but it includes a fan that blows air across the internal pad for increased water evaporation. They can generally produce a gallon more of humidity each day compared to the bypass device.
- Steam Humidifiers heat eater electrically until it boils and creates humidity in the form of steam even if the furnace is off. The system blower picks up the steam and pushes it out through the vents.
