How Does Furnace Humidifiers Actually Work

The furnace’s main task is to produce the heating air and the humidifier moisturizer that heat before ending it from the machine into the actual room. Now, this process of humidification might differ depending on the type of device you are using. 

Because if you’re using a fan-powered humidifier, then the air would get flow through the water, some of this air would evaporate during the process, and some moisturize the air. 

Now another type of humidifier is the bypass humidifier. In this, the process is slightly different in which the air gets passed through the soaked pad while carrying the moisture also with it. 

Furnace Humidifiers vs Console Models Comparison

Many people get confused when it comes to these devices, but to put it in simple terms, console humidifiers are those models which work on plug and play basis. On the other hand, Furnace humidifiers need to operate in the HVAC system to make use of them. 

Now, the usage of these two devices is quite similar, and that’s to humiliate the workplace or the home for people living in an environment that demands heated air. 

  • Compared to the console models, an air of furnace humidifiers gets spread in the uniform direction across the various rooms or offices because these devices are connected to the ducts.
  • A survey found that furnace humidifiers produce four times more humidity than the console models.
  • The maintenance of a water pad or furnace humidifier filter requires replacement semi-annually or annually. On the other hand, console models require a lot of time and effort to maintain them in the correct condition. 
  • If you compare the furnace humidifiers’ prices, they come costly compared to the console humidifiers.
  • Those who have large houses or rooms should use furnace humidifiers to cover the large area easily. Console humidifiers, on the other hand, are good for small rooms or houses. 

How to choose the best Furnace Humidifiers: Buy The Right Furnace Humidifier

Buying the right type of humidifier is still one of the most challenging decisions for most users. To make it simple here, we explained different types of units that will help you make the decision. 

1.Types Of Different Furnace Humidifier 

(i) Drum Humidifiers

The mechanism of the drum humidifiers is made with the usage of the rotating drum. Here the rotating bypass tube is connected through the rotating drum to the source water. All of the air going through the ducts passes through this tube, and it’s moisturized through evaporation and ultimately disappears. 

(ii) Flow-Through Humidifiers

This machine uses a similar water evaporation method and a tube also. But, here, the water flow is different. A constant flow of the water is sprayed on the humidifier pad, and the process of the humidification works in a never-ending loop.

(iii) Fan Powered Humidifiers

Not everyone has a large space to set up furnace humidifiers, and if you are also going through the same condition, then the fan-powered humidifiers would work great for you. Here you don’t need to worry about the tube, bypass ducts, or any other thing because the air is passed through the fan. These humidifiers require less room or space to set up, and that’s why people love them.

(iv) Steam Humidifier

Compared to the humidifiers mentioned above, a steam-based humidifier works best in any case when it comes to the most powerful device. These humidifiers use electricity and steam instead of an evaporation mechanism, which manages to produce more moisture levels to keep the room hot. You can also control the temperature of the room quite easily with steam humidifiers. 

2.Room Coverage Of Furnace Humidifiers

The big question which every customer has asked us is how much room does the furnace humidifier cover?. It might be hard to say the exact number, but a good furnace humidifier easily manages to cover 1500 square feet without any issues. If you decide to go with premium quality dehumidifiers, then you can expand them to cover 3000-8000 square feet of the area for sure.

However, make sure that the humidifier fits right to the house size yours. Because a bigger humidifier will result in more moisturization resulting in waste of electricity and water supply. On the other hand, the humidifier shouldn’t be so small that it does not cover the space fully, so strike the decision of buying the furnace according to the area of room these machines cover.

3.Set Up And Installation

The installation process for each humidifier depends upon the type you have bought. Because if you select a drum furnace humidifier or flow through the machine, then these are installed to the bypass ducts. In this installation, the air intake would be done through the supply plenum, and from the outer duct, the most will be dispensed. So ultimately, it’s a choice of yours whether you want to install the plenum or air ducts. 

One piece of advice we would like to give is when you’re installing a steam humidifier, then get the help of a professional. Because the installation process of heating would be difficult in these machines and normal people who don’t have experience should avoid it. There might be cases where you will need to have a special powered outlet because most of the high-powered humidifiers operate on 240 volts. 

4.Humidity Output

Even if you like using humidifiers for some reason, you should know that there is a limit to their usage. Depending upon the type of humidifier you’re using, they still can produce 12 gallons or 19 per day, and it shouldn’t be more than that. You should ensure a good amount of water tank available in the humidifier because that would be necessary. 

To check the humidity level, have a closer look at its daily usage and then make a proper benchmark based upon it. Because that would be quite important considering every other factor. 

5.The Weight And Dimensions

A home furnace humidifier needs to be attached to the HVAC system of yours, and that’s what you should know about the dimensions of the humidifier you’re buying. There might be the occasion where you would find your room too small for the humidifier and need to make adjustments based upon it.

So when you’re buying, make sure that the humidifier is not that heavy, and it’s easy to install. If you have a larger house, there shouldn’t be an issue with the dimensions because of so much space. 

 6.Compatibility

One of the key elements of buying a humidifier is that it should be compatible with the HVAC system because otherwise, there won’t be any point in buying it. 

If you have a pre-installed HVAC system with a heat pump and thermostat, then you will have to make sure that the new furnace humidifier you’re buying also fits in. 

7.Cost

One of the most basic yet quite important things about buying a furnace humidifier is the device’s price. Now the cost of a furnace humidifier would differ from the brand you choose to install, and you should also don’t forget to consider the cost of installation. Because many people don’t know how to install humidifiers properly so if you hire professionals for it, consider adding that cost to the budget and make a proper decision based upon it. Still, here is the expected price range of the humidifiers.

  • The flow-through humidifier’s price range is around $200-250.
  • Drum and bypass machines would cost around $150-250.
  • Steam humidifier’s price is around $450-700 or more.

Steam units are usually priced higher, and if you consider the price of installation, it will cross $ 1500 quite easily. Furnace humidifier would be around $500-1000 easily. 

8.Warranty 

Warranty would give you a safeguard against something bad happening to the furnace humidifiers of years in some abnormal situations. It would help if you didn’t forget about the quality and terms and conditions you are buying the machine along with it. Get at least one year of warranty because that would save you from any additional repairing cost for sure. Some of the best humidifiers in the market are giving like 5-10 years of warranties also.

The Installation And Maintenance Guide On Furnace Humidifiers

Many people get confused when it comes to installing the furnace humidifier, so here we tried to explain the process in short and precise ways.

  • First, take these actions on the place where the furnace humidifier will be installed:- Mark the area with the help of a felt tip, then drill holes around that area, use aviation strips to cut the outline. Then position the mounting plate and use sheet metal screws for fastening it perfectly. 
  • Place the humidistat on the top of the furnace humidifier on the plenum:- first of all, Mark the holes again with a felt tip and then drill in them. Attach the humidistat to the mounting plate.
  • You can refer to the manual installation guide to check you have connected the humidistat with the furnace perfectly. See the wires are properly connected and don’t forget to put them on the transformer. 
  • For attaching the humidifier, you can use screws to connect the solenoid valve to the humidistat. While doing that, make sure wires are placed at the correct position and torque till it gets fully fastened. 
  • Now for connecting the waterline. Use the saddle if it’s usable. If not, then you can connect it by using the bypass line. If you are eligible to use the saddle, install it to the waterline and connect it with a furnace humidifier. 
  • The steps mentioned above are written after our personal observation; you are still advised to check from the user manual guide and take the professional’s help if required at any place. Because sometimes the actual condition and experience would be different from what we are celebrating here.
