Question about Honeywell HE220A1019 Whole House Humidifier Humidifier

1 Answer

Install HE220 HoneyWell , humidity not increasing in the house.

I installed my unit on the air input side, so it's located before the heppa filter on the cold air return side of the furnace. I let this puppy run all night, by keeping the fan engaged all evening. My humidistat was installed in the cold air return in about the same location as the humidifier/furnace. I noted the humidity switch engaged at about 28% upon installation and after running for about 5 hours was creeping towards cut off at about 38%.

However an electronic humidity measuring device on the machine never registered about 26% even though the unit ran all night. I need to get my humidity up to about 40% in the winter -- so if I ran this thing all night and never got more than 26% -- can someone tell me what is going on here?

Water is running through the unit, to the humidifier, through the heppa filter into the furnace before ejecting into the hot air vents. Is my furnace drying the air as quickly as it's pulled into the furnace? Honey well directions said it could be installed on the hot or cold air side. I chose the cold air side due to ease of location to install. Was that a mistake? Any other ideas?

    I have a similar problem. Same installation; I moved the humidistat up 6 in above duct work and humidifier. I feel the humid air when I open the humidifier but its still dry in the house. Even with the humidistat turned up to 60%. I too have the water line installed on the cold water side. Does that really make the difference?

You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.

Too much water running through to humidifier


With the Honeywell he220, you will use alot of water, trying to turn down the water will only reduce your amount of humidity in the home, you may be able to adjust it a little but you need to take the cover off and reduce the water flow a little at a time watching the water as it flows across the pad, you just have to make sure the humidifier pad is getting plenty of water across it, to little and you lose your humidification, hope that was helpful to ya, thanks for your question,

No increase in humidity after installing whole house humidifier


have you checked the damper ? is the motor running the right direction ? have you increased the water supply to it ? you need to be sure that it is coming on only when you have a call for heat, normally your humidistat should be installed near the return, or on the return duct, for proper sensing, you could try holding a pan of steaming water, placing the stat above it, not to close, to see if the stat shuts off the hum, a little trick, that way you will know if the stat works ok, hope these helped, thanks for the question, mr.grzz

Honeywell he220a install


thanks for your question,
you have to install the bypass humidifier on the supply side of your heating system, (hot side) and run a bypass pipe from the return side, (cold side), it does matter which side it goes on, you do not want water vapor going directly into your furnace, as this can damage it and shorten the life of it, your humidistat is installed on the return side of your duct work, this will allow proper operation of the unit as the humidistat senses the moisture in the air and brings on and shuts down the humidifier as needed. hope that helped to answer your question, please let us know what you think, again thanks, mr.grzz

Depends on how this humidifier operates. Most now using water in from a valve let the excess water on through the pad and down the drain and have no sump or pump because of bacteria build up (Legion Aries Disease).

Also as outdoor temp drops you need and air is only able to "soak up" just so much humidity. The air will hold more moisture at 45'f than at 25'F. And you need less humidity at these levels do do some of the same job like static electricity, and keeping wood from drying out...

If this helps you please rate me as high as you can and thank you for using fixya..

Lack of humidity


Try the following test, ( I will resume this is a flow through humidifier)

Spray water directly oin the filter make sure it is saturated. Some water should leak from the bottom. After 10 min measure the Humidity to see if this helped. If there is a higher level of humidity the pbm is that not enough water is saturating the filter. Check the level of the filter & water feed nozzle.

Option 2 is to connect the water feed tube to a Hot water source.

Hope this helps.
