Benefits of Installing A Furnace Humidifier

Installing a whole house humidifier to work with your home furnace will provide optimal humidification throughout your entire house. Whole house humidifiers work with the home furnace to distribute moisture efficiently to all living areas, whereas portable models are only capable of treating moisture areas in smaller areas. Humidifiers installed with the home furnace use little energy and require minimal maintenance, making them a more user-friendly option.

You can optimize the function of your home furnace by installing a whole-furnace humidifier. A furnace humidifier fosters proper distribution of moisture throughout your home, protecting you or your family from dry air during winter. Dry air can cause skin irritations and allergies.

Benefits of home furnace humidifiers

Below are some key benefits of installing a furnace humidifier:

  • Good health: You can improve your family’s well-being by treating dry air throughout your home. Home furnace humidifiers have been shown to improve lung health, alleviate allergy and asthma symptoms and reduce instances of illness.
  • Winter comfort: Properly humidifying your home during winter can make the space feel warmer. The efficient use of energy by a home furnace humidifier can lead to energy savings, since your home will feel warmer at lower temperatures.
  • Protection of furnishings: Stabilizing the humidity levels in your home with a furnace humidifier can help preserve wood. Maintaining proper humidity can protect wood flooring, cabinets and furniture from cracking and drying out. A dehumidifier can also reduce the static electricity in your home.

Types of home furnace humidifiers

Whole-home humidifiers work directly with the home’s furnace system. There are three main types of home furnace humidifiers, each of which operate differently:

  • Bypass humidifiers: Installed on bypass ducting, these units are only active when the furnace is in use. These humidifiers have no motor, instead relying on the furnace’s blower motor to circulate air through the humidifier. These systems moisturize air with a water panel.
  • Flow-through humidifiers: These models are installed on the furnace’s return or supply plenum. Flow-through humidifiers use a built-in fan to move air through the humidifier’s water panel, so you can use these humidifiers even when the furnace is not running.
  • Steam humidifiers: This type of humidifier boils water, creating steam that mixes with air circulating through the home furnace. Steam humidifiers produce more humidity than bypass or fan-powered models, but they draw more power.

Home furnace humidifiers versus portable furnace humidifiers

Both home-furnace humidifiers and portable humidifiers have benefits. Here are the pros and cons of each type of humidifier:

  • Space: Installing a home-furnace humidifier results in less clutter than using multiple portable humidifiers. With no tank to fill, you save additional space by connecting directly to your water supply.
  • Efficiency: Home furnace humidifiers require less maintenance than portable units. You can save time refilling reservoirs by connecting the humidifier directly to your water supply. Also, portable units must be cleaned and descaled regularly, while whole-home models require only annual maintenance.
