What is the major difference between the flow thru and the drum type?
Typically, flow-through whole-house humidifiers are around 30% to 40% efficient. For example, for every gallon of water delivered into the air, 2 gallons of water flow through. On the other hand, drum whole-house humidifiers are 100% efficient. All water supplied to the humidifier is transformed into humidity.
What is a drum humidifier?
Drum Humidifiers A drum humidifier consists of a rotating drum equipped with an absorbent pad. The drum moves through a pan of standing water, which the pad soaks up. As air flows through the bypass tube, water evaporates out of the pad and into the air.
What is the difference between flow through and bypass humidifier?
When comparing the power humidifier to the bypass humidifier, the major differences are that it has its own blower motor and does not rely on the furnace blower motor. The fan delivers moisture to the supply, which sits above the heat source.
Do flow through humidifiers work?
A steam humidifier heats water to create steam that is injected into the furnace airflow. Of the three, flow-through humidifiers are often preferred because they are more reliable and usually more hygienic than reservoir types, and they are less expensive and use less electricity than steam units.
What is the difference between flow-through and bypass humidifier?
How much water does a flow through humidifier use?
Depending on the model you choose and the size of your home, a humidifier uses from 1.5 to 12 gallons per day when the furnace is operating. This minimal amount of water is enough to raise the humidity to your desired level, but not enough for you to notice a difference on your water bill.
What is a bypass damper on humidifier?
A bypass humidifier requires bypass ducts, taking up extra space in your home. It also uses a bypass damper that must open to operate, shutting off off in the summer when you don’t use it.
