20 Most Recent Honeywell HE220A1019 Whole House Humidifier Humidifier Questions & Answers

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,

thanks for you question,
the residue that you are seeing is Calcium, it is a natural mineral that is found in all water, the easiest way to remove the calcium build up from your humidifier screen is to use (CLR) it is a calcium, lime and rust remover, a simple diluted mixture with water, then soak the screen for about half an hour, rinse the screen then reinstall, a soft water system would help with the calcium build up as well, but tend to be alittle on the spendy side, your could try inline mineral filters that need replacing yearly, I really hope that helped ansewr your question, let us know with some feed back, thanks again for your question, mr.grzz

I don't know much about humidifiers other than they are rarely needed and most folk around here would rather there was a lot less humidity., especially considering how easily black mould grows and how injurious to health that can be. Those few people living with an unsuitable heating system in a badly designed house usually find it is adequate to have a water feature in the lounge or to balance a bowl of water on a radiator. Certainly when the windows sweat to such a degree, especially if you have double glazing, the humidity must be well above the comfort range, above 70%, and probably well into the moist range of 80% - 90%. Higher than that and any exertion becomes decidedly unconfortable... I am guessing the humidistat is either faulty or cannot work because the humidity is already too high. I suggest you need to check the humidity in your home with an accurate independent humidity meter before you go further...

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

I would think it would need to switch on & off to control the water flow through for correct humidity..

Make sure the new pad you installed is in the right position. The pad is marked with a black dot about the size of a quarter. This end should be up for proper water flow through the pad.I fwater flow is being restricted at the pad the vibrating nosie that you are hearing is the dry portion of the pad vibrating agaist the platic housing of the humidifier. This noise stops once the pad has absorb enough water in this area of the pad.

i was just reading up on this and comments from others say that there is a solenoid that is stuck open because of mineral (lime or calcium) build-up

Try removing the cover, and manually cycling on the controler switch? Does the solenoid click on, next to the humidifier (the unit with the water line running through it, with wires coming out of it)? If it does click on, is water running down the water pad? It doesn't necessarily drain water when it's working correctly. All of the water SHOULD be getting evaporated into the air return duct.If it's clicking on, but no water is running out, you should check the water supply saddle valve and make sure it wasn't turned off during servicing.If it's not clicking on, you should test that you are getting voltage (12v-18v DC) to the solenoid. If you're not, check all wiring connections and make sure they're tight. If you still don't get power, you have either a problem with your control unit/humidistat, your DC power supply, or the control board on your furnace. You may need to call a HVAC technician at that point, depending on your comfort level/skill level in that regard.When you say the solenoid "stays hot" do you mean it's physically hot to the touch? Hotter than the water lines running into it?If the solenoid is getting hot, it probably has a bad coil, and if you continue to operate it, you will probably burn up your DC power supply.If you're getting voltage, you have water pressure, and the solenoid is still not opening, replace the solenoid.

HI I have similar isssue with HE220 but in my case the water run through all ththe time, even when unplugged from the power outlet.Would that be solenoid issue?the unit run fine for last season so the wiring is fine.Any ideas would be greatly appreciated.
