How is this unit any different than the Honeywell flow through/bypass ones? The Honeywell ones are bad and don't work.
Asked by: bexster
To respond to the tech support folks: thanks for taking the time to respond. The Honeywell has major solenoid issues. The air pressure switch to turn the unit on when the furnace comes on does not work. Once you get it operational, if you can, it wastes a tremendous amount of water and is designed to only put out 20-28% humidity, regardless of what setting it's on. As I already have all the holes due to the failed Honeywell experiments, I was wondering if this would perform better.

is drain required for this unit?

is drain required for this unit?
Asked by: Baga
Yes. Water is released in short bursts at the top of the unit and trickles down through the pad. Excess water runs out the bottom through a hose to a floor drain or equivalent.

PEX Water Supply

I only have PEX piping for my water supply in my home as it is new construction and this is all that was used. Am I unable to use the included water valve connection to connect my water supply? is there an alternative method I can use to make this connection?
Asked by: dasmikechen
You would need to use an adapter first before connecting to the water supply.

Mounting on warm air plenum

My furnace has the return air duct below the motor and the warm air plenum above it, so they are separated by a good 3 feet from each other. I think in this case I need to install the humidifier on the warm air side, but will it work as well? What is the compromise if both the bypass and the unit are mounted on the plenum? Since there is no fan, I don't see how the air will go through the unit...
Asked by: Jacs
My installation required mounting the unit on the hot air plenum and feeding the air back to the cold plenum and it worked great. Rigid duct work was used instead of the supplied flexible duct. The air in the hot plenum is being forced and will try to escape through any opening. The cold air plenum is at a lower pressure and will draw the moistened air from the unit.

Installation was reasonable, but I would not recommend it for the inexperienced or unhandy. I have had some problem with the damper not staying in position. It is pretty much all plastic, but seems a reasonable product for the price, assuming that it lasts a few years.

A little slow to raise moisture level in 2000 sq-ft house but eventually gets there. Installation instructions could be clearer.

Rated 5 out of 5 by from Great Humidifier for the Price and Everything Needed for a Typical Installation is Included I have owned a 12HF for several years and have had good luck with my unit and recommended it to a neighbor that had mentioned their house gets dry in the winter. I did my own installation, so I offered to help them once they received their humidifier and a little over 2 hours later they were set. What I like about this unit compared to other brands is that it comes with everything needed for typical applications in one box and it has a plug-in transformer so no hardwiring is involved. Plus, it uses a lot less water than most other brands out there; the water valve on most flow through style units is completely open when there is a call for humidity, but this unit adds water in pulsed intervals. Lastly, maintenance is very low. I just put in a new evaporator pad at the beginning of each season and wipe out the shallow drain pan area to remove any mineral build-up.
