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.

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.

Rated 4 out of 5 by from A quality product This humidifier works as expected and installed relatively easily with basic HVAC tools and knowledge. I didn't run across the leaking problem that others had mentioned. I did meticulously make sure the unit was installed level. The supplied 6" duct was long enough for my application. I connected the power source to my furnace circuit board rather than an AC outlet. I would have given 5 stars, but product has only been in service two weeks. I can't comment on long term use. I have noticed house feels more comfortable at lower set temps.

Rated 3 out of 5 by from Works Great but the installation may need enhancements This humidifier would be rated 5 stars for an application that requires no adjustments to the supplied installation plans. My basic, forced air furnace is installed so that only one side of each vertical plenum is accessible. It was necessary to install the humidifier on the wide side of the hot air plenum and then use rigid 6” round duct work to feed the unit’s output into the horizontal cold air plenum. This unit is designed to fit the flexible duct that comes with it. The output port of the unit is much smaller than the female side of a 6” round duct so an adapter had to be fabricated. By hammering out the crimps of the male side of a 6” elbow, it then fit nice and snug onto the supplied plastic starter collar. During testing, the pulse module never came on in the normal setting. The “LO” setting worked but would continue to pulse water for 15 minutes after the furnace turned off. An outlet was installed on the side of the furnace for the unit’s AC adapter. This outlet was wired to toggle on and off with the furnace fan. I was then able to leave the pulse module setting on low with the unit automatically shutting down when the furnace fan turned off. The unit works perfectly now, but I feel installation enhancements such as this would be beyond the ability of many home owners. The media pads are not carried at Home Depot and must be ordered on-line. One pad should last an entire heating season. In summary, this type of humidifier, with a flow through water system, is the only kind to use. I’ve had plenty of bad experiences with the rotating drum, water bath, calcium clogged nightmare types to never go back.

Rated 5 out of 5 by from Great Product. I mounted it to the flex duct return. This is a great product. I read the reviews online and discovered the Honeywell model has issues, so I went with Hamilton. Very pleased and zero regrets. I have a 1,600 sq. ft. house and this unit can make the windows drip with condensation (I actually have to turn it down). No moving parts (except the water solenoid), no slimy drum to clean out, and best of all no humidifiers to refill. See the pictures, attached. The directions say it can be mounted to either the return or supply ducts at the furnace. I have a flex duct return, so I wanted the main body of the humidifier mounted to the solid surface of the supply duct. The directions did not describe this scenario, so I improvised. I hope the attached pictures and drawings help someone else in the same boat I was. I did have to install a 110VAC outlet for the power. However, I already had an existing drain (for AC condensation), for the drain tube. The unit works beautifully and no more dry skin. Great job Hamilton!!!

Rated 3 out of 5 by from Finally installed...not easy. I will update the performance I bought this product because it was advertised and the reviews stated the installation was simple. It took me about 4 hours to install it. Admittedly, most of this was due to my lack of knowledge, but a LOT of it was due to the poor installation instructions that came with the product. In particular, there was no information available on how to wire the system. No color coded, or keyed electrical connection. I called the company; closed on Saturday. I scoured the interned....nothing. I decided to just give it my best guess - IT WORKED! I assume the polarity doesn't really matter. There are many other gaps in the instructions that require some patience and careful reading. A few hints: -Buy good tools to cut the duct work. This was the most time consuming and difficult part (except reading the instruction and researching). -You have to take the humidistat apart to determine which connection is "COM" and which is "NO". -MAKE SURE you buy extra 6" flex duct. The amount supplied is not sufficient. -You will need some extra wire for almost any installation. -You will need extra wire nuts (2) -You will need duct tape -You will need a 3/4 wrench and a 5/8 wrench (instructions didn't say what size) -The wires that run between the controller and the valve don't seem to matter which wire goes where - or I just go lucky....not sure. -The hole in the duct work for the humidistat must be completely opened up to fit the mount. Go slow and make sure you understand what you are doing before cutting - the instructions suck. It is a warm and humid day, so I can't say if it works properly. It test mode, it seems to work. I will update the review in the coming months to rate the performance. I am worried the installation may affect the performance. Again, the instructions need to be more complete to help the average home owner.

The directions that came with the unit were older and were missing critical info of the sensor placement. I downloaded the updated directions that solved the problem. Depending on your system it is unlikely to have this work on both the heat cycle and fan only cycle. I called the product help line. The folks there were very knowledgable of their product and how to set it up.

Rated 5 out of 5 by from Hamilton Humidifier Easy to install. Only minimal sheet metal alteration required. Home Depot met all expectations and then some. I felt unit was fairly priced and customer service by Lauren was excellent. I am recommending to others.
