Honeywell Bypass Flow-Through Humidifier
Mount unit on cold air return
I installed this unit 3 years ago and have been very happy with this unit. I followed the instructions on the DVD. Took me about 4 hours to install at a casual pace. I installed the unit on the cold return and siliconed around the unit to eliminate whistling. Ran the drain hose to my sump. It maybe drains 2 gallons a day at worst. Not as bad as some reviewers report maybe because of mounting it on the cold return. The replacement pad is only $10 which I replace every winter. 3 years later still working perfectly.

easy install, large water waste
After going thru my fourth drum type humidifier in 10 years I decided to try something different.
The water in my area is now extremely hard.. My last two drum type humidifiers were completely incrusted within 6 months.. cleaning them is problematic to say the least..
So.. I tried a flowthru this time..
The Pros: Easy install!, uses the same 24 volts as most existing humidifiers, so if you connect it to the transformer that is connected to the Fan wires, you dont need the flowmeter thingy nor the humidistat (again, this only wotks if your replacing an existing system, that was wired with the tranformer only turning on with the fan)
Uses the same water connection too.. so again.. super easy to install this thing..
The Cons: its way overpriced.. if you never had a humidifier before, then you would need all the stuff that comes with it.. otherwise your wasting $75 on useless stuff you dont need..
ITS WORST PROBLEM IS HOW MUCH WATER IT USES!!
10 gallons a day!
HINT: I ended up added a small tap inline with the water feed.. turning the water flow down to the barest minimum.. This trick still keeps the house humidified, but your not wasting as much water.. (i got it down to maybe just a gallon a day)

Flow thru humidifiers
Flow thru humidifiers are an environmental atrocity. Mine wastes between one and four litres of HOT water per hour. Only if it had a recirculating pump would I consider getting one. So I calculate that since the beginning of the heating season my humidifier has sent at the very least 2000 litres of hot water (and perhaps much more) down my drain. So much for the energy saving of my new high efficiency furnace.
And furthermore, this humidifier does a truly lousy job of humidifying my house, whose humidity level is now at 20%, and it is not even that cold outside, causing us to feel dry, wasting further energy in heating costs, and damaging my valuable musical instruments. With my previous drum humidifier I was able to keep the house at or close to 50%.

Honeywell Bypass Flow-Through Humidifier
I've had this exact unit now for 10 years, worked well. (I think). I just had my furnace replaced, and wanted to use the same unit. The installer told me that the solenoid valve (what controls the water flow) was shot, and that I was constantly running water thru the system instead of just running when the furnace was on. He suggested just replacing the solenoid valve.
Imagine my shock, to replace the valve, $110 plus tax! Be warned with Honeywell.

Try mounting it on the cold air return duct
I actually installed the unit the way the instructions mention, on the hot air duct. However it became very obvious that the cover of the unit was not designed for the pressure of the blower unit and an annoying whistling occurred. After a couple of days of whistling, I decided to reverse the unit and mount it on the return duct instead. I figured if the air blew out on the Hot air side, it would draw the cover tighter on the return duct. That was the case. I would also recommend that the Solenoid jumper be moved from ânoneâ (meaning it will pulse regardless if the furnace is running or not) to âWarmâ or âHotâ (meaning it will only run when the furnace is operating). Unit is working fine and now is quite

Flow through not the way to go
I purchased a flow through humidifier a couple of years ago and had no trouble installing it. I noticed that it had a hard time increasing the humidity in my home even though I followed the ideal install conditions...hot water supply, mounted on the hot air duct. Despite this, it still didn't cut it. In addition, mold growth was pretty quick on the evaporator pad. I installed a new pad at the beginning of the season and by February or March, the pad was consumed by mold and was already deteriorating.
I would not recommend this style of humidifier to anyone. Drum humidifiers are still the way to go. They may use a little more water and have a motor to maintain but at least they work.

A GOOD CHOICE
I purchased this product the past winter. It had no problem bringing up the humidity to 35%. It made a huge difference. I installed the humidifier directly to the 24V output on the furnace. A big plus with this model is that it utilizes patented water saving technology. This basically cycles the water on and off, instead of being on as along as the furnace is running. A couple of small issues though. The drain hose was too short. Also, some parts were missing from the box. Check before you buy! On the whole it was a worthwhile investment. The company is also Canadian based, so that was a plus.

Not bad will know for sure in 3 - 4 days
(2000Sq ft) OK, box diag contradicts the actual instructions
Con - Wiring, vinyl vent hose and water supply hose to short, bought longer sets.
- Seal where unit comes together (cover and back) doesn't seal well.
-24hs, fan on cylinoid = none, humidity up by 12%
Note: after much research did use the saddle valve on my Plastic water line with no issue whatsoever, instructions say not to.
