What is a Whole-House Humidifier?

Whole-house humidifiers are usually controlled by humidistats that detect moisture in your home’s air. They let you choose and sustain the humidity level either using a digital or manual model available.

You will be running your furnace blower system with the whole-house humidifier as well. Moreover, that’s a plus, since you don’t need to do anything—except for seasonal maintenance.

The other option is to run a portable unit that requires more maintenance and does not humidify the entire house—it is used for individual rooms.

Whole-House Humidifiers—are attached to a new or existing furnace with a separate water pipe or tube from the plumbing in the house. There are several types available where one type injects a water mist into the airflow in the ductwork. Another type uses a foam cylinder rotating in a tray with water that blows through and around it. The whole-house setup lets you keep your humidity level at your desired percentage. You will never need to fill any tanks or worry about it running dry. It makes no sound and the initial cost is not as costly as portable units are. They cost only pennies each year to operate.

There are systems offered for baseboard or radiant heat systems. Everyone can have humidity in his or her environment today without a problem.

Humidity not only provides health benefits, it also keeps furniture, floors, plaster, musical instruments, and electronics from drying out, warping, cracking, and deteriorating. Wallpaper will start to crack and peel off.

Humidifying units need to be installed by a professional or it can be done by you. Some units do accumulate mineral deposits and it is vital to clean it with diluted distilled clear vinegar at the end of your heating season. When the deposits from hard water solidify, they are difficult to remove, yet it can be done. Some homes use soft water systems and that would be a plus for the whole-house humidifier system.

Portable Humidifiers—stand alone, usually with casters to move from room to room, and have a water reservoir that you fill and maintain. They are electric and plug into a standard 120-Volt outlet. Several rooms at one time can be humidified with more powerful portable humidifiers. Additionally, small tabletop units are in the marketplace but do not have a large range of coverage—enough for a small bedroom or office cubicle space.

The portable unit is perfect for a renter or a student in a dorm room. They are efficient and will keep a smaller space humidified.

On the downside, a best portable humidifier is more expensive than a whole-house humidifier. The furnace’s blower is used for the whole-house unit whereas a portable unit has its own blower to use its own energy. Portables are heavy, and a little noisy. Maintenance is done more often, depending on how often it is used, and the water reservoir needs to be filled almost daily. Some units have removable tanks and others need water taken to them.

They must be kept meticulously clean. Standing water is the home for bacteria, mold, mildew, and fungus just waiting to be emitted into the indoor air you breathe. That would have an adverse impact for allergy and asthma sufferers.

Choices for Whole-House Central Humidifiers

Different varieties of humidifiers for a central system—entire house or whole-house—are dependent on what you want to accomplish and what your budget allows.

The central humidifier attaches to your forced air furnace between the hot air ductwork and cold air return for heat, air conditioning, and humidification to enter the rooms of the house. The hot air is redirected into the humidifier, and the air being hot and pressurized, will hold the moisture going back into the cold air return to be heated again. This air is sent into the house as water droplets evaporating into the home’s air in all rooms via the air vents in each room. Each room should have an air return, but sometimes a large air return is created by HVAC technicians for a new furnace installation to accommodate the need based on square footage and power of the furnace. The basic types of humidifiers are Bypass, Fan, and Steam.

Central Humidifier

Image source: hometips.com

Bypass Humidifiers use the warm air from the forced air furnace to put moisture into the air in the home. They do this by pulling warm air from the heat ductwork then sending it through a water panel, known as a filter that distributes vaporized moisture into the entire house. These units are installed on the supply or return air plenum (where air is pressurized for circulation) of a forced air system. When there is no floor drain, there are drainless bypass humidifiers offered in the marketplace. These units recirculate their own water, saving on water usage, and plumbing to remove condensation. The bypass is middle of the road considering functioning and cost. A good example of a bypass humidifiers are the Aprilaire® Bypass Humidifiers.

Fan-Powered Evaporative Humidifiers work similarly to the bypass humidifier except it uses a fan to blow the air across the water panel filter pad to boost the water evaporation. These units can produce a gallon or more of moisture daily compared to the bypass types. These humidifiers do not use bypass ductwork so it can be installed in smaller spaces that are great for homes built on concrete slabs or a furnace installed in a closet room where there is a crawl space under the house. The Honeywell® HE300A1005 TrueEASE™ is a good model.

Steam HumidifierSteam Humidifiers heat water until it boils to put moisture into the air in the form of steam. It is sometimes called a mist humidifier. The blower in the furnace sends the steam through the house by the ductwork through the vents into the home. This is a fast and efficient method for comforting humidity. This type of humidifier will provide moisture as needed and is the most expensive. The Aprilaire® 800 is a good steam humidifier to consider. This unit works independently of your HVAC system for larger homes. The Aprilaire® 800 Automatic Whole-House Steam Humidifier is a good unit for specific house sizes.

 

What to Look for In a Best Whole House Humidifier

Humidification is the process of adding moisture to the air and is one of the most important aspects of total indoor comfort.

  • A whole-house humidifier is designed to cover the entire house, but it is still important to check its actual coverage. Some units can be used in a house that is 4000-square feet and some can only humidify up to 2500-square feet.

  • The higher the evaporation rate means the more the air will become saturated with moisture over a specific time.
  • A humidifier with an automatic humidistat will calculate the humidity and adjust the moisture output as necessary.
  • Some units have automatic control features and others have manual controls. It’s a personal preference and a budgetary consideration for what works for you and your needs.
  • Humidifiers that interface with a gas-forced air heat furnace might require a licensed HVAC professional to install. Some manufacturers will void their warranty if the installation is done by a do-it-yourself person.
  • Check maintenance requirements to avoid spending money and time unnecessarily. Today’s humidifiers are so technologically advanced that only a minimum amount of cleaning is required with filter changes.

Benefits of a Whole-House Humidifier

When days get colder, or if you live in a warm dry climate year ‘round, you will want to put humidity into the living environment with your body benefiting with a humidifier. Most everyone is aware of the small portable humidifiers and vaporizers used for babies. The tank is filled with water and the unit is moved from room to room and when the water runs out, you fill it again or turn it off.

On the other hand, a whole-house humidifier has many advantages. It is installed into your heating and cooling system. The water vapor starts at the source—the heating ducts. It is then controlled with your thermostat (temperature) that has a humidistat control as well (humidity). The level of humidity can be set by you and it will be constant. The water line is hooked into the plumbing for the house, so it’s a simple process to do. This provides you with:

  • Low maintenance—check the filter occasionally
  • Whole-house humidity—without thinking about it
  • Water tanks—none to fill
  • Blower—none to purchase since it uses the blower in the furnace
  • Moisture—beneficial to wood furniture and floors
  • Health benefits—skin is moist, lips are not chapped, no stuffed up congested nasal passages or sinuses, dry skin, allergies, and the plants love it

Tips

  • Do not use essential oils in any humidifier even if the manual does not address it. The oil will gunk up the works.
  • Hard water creates minerals that adhere to the unit. It would be best for your humidifier to use distilled water. Boiling hard water will not remove minerals.
  • For every degree you drop your thermostat, you will save up to 4% on your energy bill each month.
