Question about Honeywell HE220A1019 Whole House Humidifier Humidifier

1 Answer

Lack of humidity

Hi, I recently installed a Honeywell whole house humidifier. It does everything correctly but does not add enough humidity to the air even with the control turned to max. Water passes through correctly and out of the drain while the furnace is on. I thought that I attached the bypass hot air to close to a direction change in the duct work and did not have enough air flow so I moved it and now if feels like I'm getting good air pressure from the hot side and it draws air into the cold. I checked the humidifier pad and it seems OK. It is easy to see light through it. Let me know if you have any thoughts.
Thanks Gene

    I have the same problem... Water runs through it, and all seems to be working. At the furnace I installed the humidistat in the cold air side just below the humidifier on the furnace. humidity seems to be going up at this point on the cold air side of the furnace. But when I measure the living level humidity I can't get it above 26% after installing this puppy....

    I'm still perplexed??????????????/

    I also have the same problem with the same type of Honeywell humidifier. A friend of mine is in the same boat. I'm not sure what the issue is... It will raise the humidity to about 25%-28% and that's it.

    Ditto, I have the same problem. Everything seems to be working as designed. I even feel the humid air when I open the humidifier unit, but when I go through the house, the air is still dry heat; humidity gauge doesn't go above 22%. Humidifier is installed on the supply (hot air) side and the duct work is connected to the cold air return side. I made sure the humidistat was installed at the required 6-8 inches above the duct work and humidifier. I don't get it, what's wrong????? Can someone help?

    I have the same problem as all above have explained with two furnaces and two humidifiers. Both serviced ares are dry - dry - dry. Professionals that have installed these units are of no help. Are there any solutions?

    My April Air whole house humidifier will not give me humidy above 22%.It was installed professionally less than 1 yr.ago.Water valve is open(left loosey)all lights on unit indicate normal operation.Should I see water in the drain tube from the humidifier?The clear tube is always dry.I was to expect humidity of 40-49%.

    The humidistat should be mounted on the return duct,higher than the humidifier (if mounted on the return), or higher than the by-pass duct. If it mounted lower it will sense the humidity right out of the unit instead of the house which will turn the humistat off due to satisified humidity level. Also The flo thru humidifiers will have water running out the drain tube. These humidifiers can go through 8 and up gallons per day.

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.

Does setting the dial to a higher number mean there will be more humidity in the system or lower humidity?

By setting the humidistat to a higher setting means that there will be more humidity produced by the humidifier. Depending on what the outside temp is that will determine what setting it should be set at.

You can turn the blower on so that the humidifier will run more... there should be a manual on detting on your t-stat that will run the blower constantly. The humdifier should be wired to go on withthe blower.
The other option would be to install a stem humidifier which will produce more humidity faster...

High Calcium in Water

Hi, Hot will make the problem worse. If your calcium is that high you will have scale in your tubs, sinks and toilets. Calcium is a pipe clogger and if you have noticed this type of scaling you may be wise to consider a whole house water filtration system, it will save you lots of problems in the long run. Good Luck!

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 Envirocaire Whole House humidifier not elevating humdity in home. Installed sev. years ago by HVAC contractor. Can't get the humid. above 30% no matter how high I turn it up. It is fed by hot...

This may not be a solution, but a couple things you might want to look at. First, the humidifier may not be big enough for your house - just because a contractor installed it doesn't mean he sized it right. Second, humidity may only be 30% locally by the humidistat, but higher in other parts of the house - it depends where the humidistat is located. Finally, look at your hot water line - I'm surprised he ran it off hot water and not cold - seems like a waste of energy to me, but the feed line may be clogged by sediment from the water heater
