You must be aware of humidifiers if you live in a dry or cold area. But do you know “what is a bypass humidifier?” If the answer is “No, ” you are at the right place.
A bypass humidifier is a type of whole house humidifier. It distributes humidity to the entire home at a time. To know everything about the bypass humidifier, read the article till the end.
What Is A Bypass Humidifier? A Detailed Guide
A bypass humidifier is a humidifier that allows control over the humidity levels of a house.
If you are new to the topic of bypass humidifiers, the following information will clear your mind.
1. What Is A Humidifier?
Before going deeper into the bypass humidifiers, first, you need information about humidifiers.
A humidifier is a device that adds water mist to the dry air to make it more moist and efficient. In dry regions, a humidifier is one of the necessities of life.
2. What Is A Bypass Humidifier?
It is crucial to maintain a healthy humidity level. A humidifier is useful when the humidity level is lower than 30%. Thus, it balances the air by adding moisture to it.
There are basic two categories of humidifiers in terms of their capacities. One is a portable humidifier, while the other is a whole house humidifier.
A portable humidifier is beneficial for a single room or limited space. In contrast, a whole house humidifier helps to improve the humidity level of your entire home.
A bypass humidifier is a whole house humidifier that generates humidity. A furnace and water panel spreads moist air to the house through ductwork.
This type of humidifier makes moisture at larger levels to balance the dry air of the whole house at the same time.
You don’t need to refill the water tank or switch the unit every time before using it. Once you have installed it , it will work on its own.
A bypass humidifier works on the principles of Central Heating and Cooling Systems.
For instance, you have seen a building where AC cooling is not limited to a single room. It is everywhere in the building. The same happens with heating systems in winter.
So, a bypass humidifier works in a similar way. It doesn’t provide humidity only to a room or a single dorm but manages the whole house.
3. Why Do We Call It Bypass Humidifier?
A bypass humidifier works through air passageways. First, air passes from the furnace through a built-in fan. Later, moist air passes through air streams to spread out.
The bypass unit is set to the HVAC system, which works through ductwork.
Ductwork is a ventilation pathway. So, the humidifier creates humidity and distributes it by air passages. That’s why the product names a bypass humidifier.
Is A Bypass Humidifier Worth It?
Have you ever noticed why your skin becomes dry or your nose starts running in winter? Or your throat suffers and your lips bleed. This happens because of dry air.
In such situations, a humidifier keeps the air balanced and protects you from attacks of dry air.
A bypass humidifier is worth installing in cold and dry weather. It protects your home from a dry and rough atmosphere.
Otherwise, dry air is unhealthy and harmful as it causes several complications like,
– Viruses and cold.
– Dry and itchy skin
– Various eyes, nose and throat infections
– Many respiratory issues like cough and asthma.
– Congestion in the nose and chest
– Static electricity
– Splits in furniture and floors
– Cracks in walls and their paints, etc.
To avoid such issues, a bypass humidifier keeps your home’s air safe and healthy.
According to the Environmental Protection Agency, 30% to 50% humidity is healthy. More or less than the suggested range causes problems.
It is very important to install a bypass humidifier. Because it controls the humidity level of the whole house equally at the same time.
Moreover, it’s a good option among other types . It is easy to install, demands less maintenance, is noiseless and so on.
So if you plan to install a bypass humidifier, go ahead. It will be very helpful to your household.
Hot Or Cold Water For Bypass Humidifier
Choosing the right type of water matters a lot in the case of bypass humidifiers. Of course, soft water is best in the bypass humidifier, but what should be the temperature?
Would hot water be a good choice, or will cold water work in an effective way?
The simple answer to this question is “hot water.” You should connect a bypass humidifier to the hot water supply line for the best results.
1. Why Hot Water?
Hot water has many benefits for humidification purposes. Especially when a unit creates mist through a furnace.
The following reasons clear why hot water is preferable in the bypass humidifier.
1.1. Evaporation Rate:
According to science, temperature raises the rate of evaporation. Because high temperature gives energy to the molecules, they escape from the surface.
A humidifier produces humidity through water vapors. If water is already hot, it will speed up the process of creating water vapors.
So, using hot water is helpful for a bypass humidifier as it enhances the process.
1.2. Power Consumption:
In a bypass humidifier system, a furnace produces warm air to mix with water. Later, the warm air stimulates the water for evaporation.
First, a furnace requires energy to warm the water and evaporate it. But, if the water is already hot, the furnace will consume less power to heat the air to higher levels.
In this way, hot water consumes less energy from the furnace. So, it works better compared to the cold water.
1.3. Germs-Free Water:
We all know hot water is free from germs. That’s why doctors suggest boiling the water before drinking. A high temperature kills harmful bacteria and germs.
The same principle applies to the bypass humidifier. If you use hot water, there will be no bacteria or allergens that cause problems.
The clean water creates a healthy mist, so your house’s internal atmosphere will be pure and clean.
Further, hard water becomes soft on heating, so if the water is hard, it will not damage the system. In all ways, hot water is healthy for the bypass humidifiers.
How Does A Bypass Humidifier Work?
A bypass humidifier works when it connects to the system. The system includes a humidistat, furnace, ductwork, drainage, wires and pipes.
A furnace connects with the bypass humidifier to produce warm air. This warm air helps water in evaporation. Later, the evaporated water moisturizes the dry air to balance humidity.
Also, a humidistat is a key component of this system as it measures and regulates the humidity level in the air.
A bypass humidifier requires a professional installation to connect every component.
Once you connect it with your home’s water supply and HVAC system, i.e., with ducks and furnaces, it starts working.
1. Working Mechanism:
First, a humidistat detects a lower humidity level in the air (as per your selected settings). Then, it sends signals to the system to start the humidification process.
There is a water panel or evaporator pad inside the humidifier. When the unit needs water, the water supply system trickles down the water to the humidifier.
On the other side, the furnace produces warm air. Then the furnace’s motor pushes the warm air to the water panel.
Warm air and water mixes through an evaporator pad. The hot air forms water vapors that flow into the air streams after passing through the furnace.
In the end, the vapors/moist air spread throughout the house from the ductwork.
This is how the whole process takes place to balance the humidity level in the entire house.
2. How Do I Know If My Bypass Humidifier Is Working?
A bypass humidifier is more complex than a portable device.
You can easily catch if your portable unit is having an issue or not working as it should.
In contrary, it’s hard to know whether your humidifier is working or not. Well, it is hard but not impossible, so no worries. Here are some tips to check if there is any problem.
Before doing anything, you should check the humidistat . Know what it says about the working mechanism.
Check out the humidistat’s meter. If the humidity has been attained, your humidifier will not work more to produce moisture. If this is the case, you don’t need to worry.
2.2. Water Supply:
If you doubt that your humidifier is not working, check the water supply. When water enters the humidifier in a normal way, it is a sign that it works
But, if water consumption is unusual, i.e., the panel is not getting water or the tank is full (not using water). Then it’s a cause of concern.
2.3. Drainage System:
A bypass humidifier also has a drainage system. A drain hose is there to remove excess water through a pipe leading to the floor drain.
In stable conditions, the hose drains excess water (or condensed vapors). So, it continuously passes water through it.
Check if water is dropping off the hose or not. If there is no water in the drain hose, take it as a warning.
2.4. Evaporator Pad:
An evaporator pad holds the water to mix it with the warm air to create water vapors. Later, it distributes the moisture to air circulating in your house.
It is one of the most important components of a bypass humidifier. Also, it is known as a filter, humidifier pad or water panel. Check out the pad to know if your humidifier is working properly.
It holds water, so minerals build up, rusting, etc., is common because of water’s quality. Change it on an annual basis; otherwise, it will affect the efficiency of the unit.
If you notice any dirt on the filter or pad, change it immediately. In other ways, a contaminated filter hinders the normal functioning of bypass humidifiers.
2.5. Common Symptoms Of Dry Air:
In the end, if you don’t notice any of the above signs, symptoms of dry air are still enough to take notice.
In dry air, you will experience some health problems. For example, breathing issues, red and itchy eyes, dry skin, cough, sinus pain, block nose or throat, etc. If you note any symptoms, check how the humidifier works.
If you don’t find anything in the system or any dry air symptoms, consult professionals. They have a better experience, so it’s better to ask them.
Where Do You Put A Bypass Humidifier?
The placement of any humidifier plays a crucial role when dealing with dry air. Even a portable humidifier demands special attention to select a position.
So, a bypass humidifier requires extra effort and attention to adjust. A bypass unit is set up in the house’s Central Heating and Cooling System.
A recommended position for a bypass humidifier is the return duct. But, according to the product, you can place the humidifier on the supply duct.
There is no need to mix between return duct or the supply duct. Both are pathways for airflow in Central Heating and Cooling Systems.
A supply duct is a vent installed on the walls or ceiling. It supplies heated or cool air according to the requirements.
On the other side, a return duct first sucks the internal air of the room. Then throws it outside of the room for ventilation purposes.
1. How To Install A Bypass Humidifier?
People find it impossible to install a bypass humidifier without any professional experience.
Yes, it requires knowledge of HVAC systems to install a bypass humidifier. But, even with the know how of central ventilation systems, you can do it yourself.
Here is a guide to installing a bypass humidifier that will help you to install it in your home. Yet you may need some practice or professional supervision for safety purposes.
1.1. Humidifier Placement:
Some humidifiers are designed to place on the supply duct, while others are on the return duct. Many latest bypass humidifiers are installable on both sides.
Most people prefer a return duct because it throws air out and furnaces use that air to heat up for evaporation.
However, if the unit can adjust on either side, make sure which is better. A side nearest to the water supply line and power supply is good.
Place your bypass humidifier to a suitable duct in your house’s ductwork with the furnace. While cutting the ductwork, ensure you do it properly.
In other ways, leaks may occur due to free spaces or improper ducts.
Your humidifier should fit in the ductwork to access the home’s air supply vents. By doing so, moist air from the humidifier will pass through the air stream to reach everywhere.
1.2. Water Supply Line:
Water is a main ingredient in the humidification process. In the case of a bypass humidifier, you will need a house’s water supply line to provide enough water.
Connect water pipes of the supply line with the humidifier. So, on a call for water, it will transfer water to the water panel or evaporator pad inside the humidifier.
1.3. Set A Humidistat:
You will need to cut ductwork again to fix a humidistat into it. The humidistat detects changes in the humidity level and starts the bypass humidifier.
While installing a bypass unit in your Central Heating and Cooling System, a humidistat is a must. Otherwise, your setup is incomplete.
1.4. Power Supply:
After setting up all the components, wiring the unit is necessary. It will connect the humidistat and water supply controls to the humidifier.
In addition, a bypass humidifier needs a powerhouse to perform the functions.
The power supply provides electricity to the furnace and the humidifier to turn on. In the end, connect all the components through wires and then to the power supply unit.
After doing all the work, check how it’s working. Has everything adjusted as it should be or not? If you find any flaws, consult with the professionals.
How Long Do Bypass Humidifiers Last?
The lifespan of anything depends upon the way you keep it. Remember, things last if you handle them with care. A bypass humidifier follows the exact principle.
Generally, bypass humidifiers last longer than 5-7 years. However, with regular maintenance and care, the duration can extend to 20 years as well. Again, it’s all about how you treat your unit.
You don’t need to refill the tank or operate it every time before use yet, it requires your attention.
After installing it in your HVAC system, you cannot leave a bypass humidifier. In this case, your product will not work in the long run.
Instead, regular maintenance and inspection keep a bypass humidifier updated and efficient. Thus, if you find anything unusual, it is easier to sort out in the initial stages.
1. How To Improve The Lifespan Of The Bypass Humidifier?
The bypass humidifier is long-lasting until it gets a regular check and balance. Although it does not demand high maintenance, attentive inspection is still mandatory.
Following are some tips that can help you increase your bypass humidifier’s lifespan.
– A monthly check-up is important to check if your bypass humidifier is or not.
– Using hard water requires extra energy to handle it. Also, it harms the unit. So, you should use soft water for the bypass humidifier.
– An evaporator pad or water panel is sensitive to the minerals in the water. They damage the filter (minerals pile up on the base) and reduce efficiency. So replace the pad annually.
– Installation of the bypass humidifier is crucial. Any extra space in the ductwork can ruin your system. Pay attention to the details if you find any duct or leakage.
– Ensure deep cleansing of the humidifier and pipelines once a year.
– The bypass unit needs electrical wiring and connection. Make sure everything is in stable condition.
Besides all, keep checking your system’s working capacities on regular ways. The methods have been mentioned earlier in this article help in checking the health of a unit.
Follow them so that you can use your bypass humidifier for more than decades.
How Much Water Does A Bypass Humidifier Use?
In dry weather, humidifiers are lifesavers. You cannot live without a humidifier when natural humidity drops below 30%. A humidifier uses water to moisten the dry air.
In the case of bypass humidifiers, water consumption is a serious concern, along with dry air.
The use of water through a bypass humidifier depends on many factors, such as;
– Model of a bypass humidifier that you are using.
– Size of the house matters a lot.
– Humidistat’s settings are important.
– Air’s natural humidity level decides the water usage of the unit.
– Also, how long a bypass humidifier works to produce moisture has a part in water consumption.
On average, a general bypass humidifier uses 1.5 to 10 gallons of water in a day.
Here the most important thing is that only 10% of total water is required for humidification. While 90% of water wastes during the process.
Besides all, this is the estimated value of water consumption. Here water leaks or poor maintenance is not a point of concern. In such a scenario, numbers will be more alarming.
1. How To Avoid Water Waste?
In cold and dry regions, the water consumption rate is significant. So, the rate of water waste goes up as well.
With many benefits, one of the major drawbacks of a bypass humidifier is water waste. However, you can control it by following these guidelines.
– Many updated bypass humidifiers have built-in water savers. Try to install a unit with water-saving facilities.
– To avoid wasting the water, you can recycle the drain water. Through a drain hose, bypass humidifiers push excess water out. Also, water that doesn’t mix with warm air goes to waste.
(All the water comes outside through a pipe to the floor drain. Thus, you can use a bucket or any technical way to recycle the water.)
– Disinfecting the water pad will reduce water wastage. A huge amount of water waste is due to contaminated water panels.
(Regular cleaning or replacing the pad makes your bypass humidifier more efficient. Further, it will reduce the amount of water on the drain hose.)
