​How Do Furnace Humidifiers Work?

​The furnace humidifiers will install directly into your heating/cooling system, and this makes them easy to use and also means that they will require less maintenance. However, most of these humidifiers will only work when the furnace is on.

​Although all furnace humidifiers will work with your central heating furnace to humidify the air in your house, different types will achieve this in a variety of ways. In general, the humidifier will work by introducing moisture from water into the air and then evaporating it into a stream of warm air from your furnace.

​Types Of Furnace Humidifier

​Although you can get furnace humidifiers from various brands, you can categorize most into three traditional types. Humidifiers from these different manufacturers will look different and also vary when it comes to the features, but the three top types are flow-through, drum and steam humidifiers.

​Flow-through Humidifiers

The flow-through humidifier is in most instances hooked up to a floor drain where it allows a light but steady stream of water to drip down on a plastic screen. Air then blows through the screen picking up moisture to humidify the air and distributing it throughout the house through the central heating system in the home.

​Drum/Bypass Humidifiers

​Drum humidifiers are probably the most common type of the furnace humidifiers. They feature a simple sponge on a rotating wheel that dips into a water reservoir and is controlled by a float. Warm air from the furnace passes through the sponge and picks up moisture for delivery to the ductwork and throughout the home. These humidifiers use a humidistat, and they will put out as much moisture as they absorb.

​Steam Humidifiers

​The steam humidifiers will use a humidistat to sense the level of humidity in the house. This humidifier connects to your water supply and pools some water into a reservoir. When the humidistat indicates the humidity level is low, the humidifier starts to heat the water in the tank. As the water heats up, it converts into steam that is then distributed throughout the ductwork by the fan on your furnace.

Things To Consider When Choosing The Best Furnace Humidifier

With the different furnace humidifiers in mind, you will have an easier time finding the best furnace humidifier in the market. But, despite the type you choose to go for there are some important factors that you should always consider when buying your unit.

​The size of a furnace humidifier is what determines the area that it can humidify and so it should always be one of your first considerations. The GPD (gallons per day) is the measure of the moisture output of the humidifier. A unit with a 1.5 to 2 GPD is perfect for houses that are 500 feet or less in size while those with 10 or more GPD are ideal for homes that are 2,000 feet or larger.

​Installation Requirements

​Even if you get the best furnace humidifier, it will not serve you well if you cannot install it correctly. Most furnace humidifiers will be designed to attach to a ductwork or a furnace, and so it is always important to make sure that whatever you buy can fit within the configuration of your furnace without requiring a lot of reworking.

​Convenient Controls

​A good furnace humidifier is one that comes with some convenient controls. Those with a built-in humidistat are a perfect choice since they offer an easy and efficient way of controlling the humidity level. The humidistat sends signals to the humidifier so that it can turn on or off depending on the degree of moisture. Units with a digital display to indicate the moisture level are also very convenient.

​Replacement Parts

​Even if you get the best quality furnace humidifier, it will still be necessary to replace some parts after some time due to natural wear and tear. It is because of this fact that you should always go for a unit whose replacement parts are easy to find and affordable. Consider the availability of filters, screens and evaporative pads and their prices before you make your pick.

​Price and Customer Reviews

Price also matters when buying furnace humidifiers but like with any other household product you should not compromise on quality to save some cash. Also, it is important to know that a high price tag does not always indicate high quality. The best idea is always to look at the features and read furnace humidifier reviews by other customers before making your pick. A simple rule is always to go for the best furnace humidifier quality that you can afford.

Furnace Humidifier Installation and Maintenance

Furnace humidifiers will require some degree of installation for them to work well. However, the difficulty of the process depends on the type and also your mechanical abilities. Most come with detailed instruction and step by step guide on how to do it and so should be able to install one with little effort. But, sometimes it is a good idea to use the services of a professional contractor, and this is more so when dealing with the steam humidifiers.

​The technology that the humidifier uses and its type are the two most important factors that will determine maintenance requirements. For example, the drum/bypass units will require more maintenance than the other types because minerals and sediments tend to build up on the belt or pad over time which can reduce or block air flow.

​Flow-through units do not require a lot of maintenance because the lack of water prevents build up of sediments. A seasonal pad change and cleaning are all you need. Steam humidifiers are the most convenient when it comes to maintenance because cleaning the unit at the start and end of the seasons is more than enough.
