Answer: 
Haha Brian, no you cant reuse that tiny amount of water. There's no separate pump included to do that, nor would you want to keep circulating that water which would only cause mold & mineral build up/scaling. The very first humidifiers just filled up a pan of water without draining the water. Needless to say they were a horrible failure from the poor air quality and maintenance required of them.

Answer: 
Without significant modifications, I don't think so. You'd have to potentially add a separate water pump and there's a good chance there'd be dirt in the water after flowing over the screen. I throttled the waterflow down with the saddle valve so there was less waste.

Answer: 
The solenoid valve for the Honeywell HE240 was tested to have a maximum capacity of 6.8 gph (gallons per hour) at a water pressure of 120psi. Most homes have a water pressure that is closer to 60psi, so the maximum flow in your application would be less than the maximum capacity of the valve itself.

Hi StansDIY, unfortunately when I contacted Honeywell, they could not tell me how much water this unit would use at the maximum setting.
They looked for more than 40 minutes for this information.

Answer: 
Hi Hello, Honeywell stated that this unit comes with a paper template for the cut out for the duct work.
Honeywell had the dimensions on hand for their larger unit, the HE280A. Unfortunately Honeywell did not have the dimensions readily available for this model HE240A.
The model HE280A cut out dimension is approximately 9.88 by 12.75 inches. Hope that gives you some idea.

I bought a humidifier HE 280 and had to install it on the return duct

This question is from Flow-Through Bypass Humidifier

January 13, 2014
The installation video shows the rubber grommet with pressure tap elbow fitted right next to the humidistat which I see as being mounted on the return duct (at least 8" from the humidifier).
I am confused with the instruction booklet explanation.
If the humidifier is attached to the return duct, does the rubber grommet with the pressure tap elbow with tube going to the pressure switch have to be fitted onto the supply duct (right above the furnace) or on the return duct to which I had to fit the humidifier?

Thanks for your help.

Answer: 
When installing the Honeywell HE280 on the return duct, which is the same as the example in the install video, you would put the grommet & elbow in the supply duct. You would then run the tubing from the elbow to the black port on the airflow switch. The tubing that comes from the humidifier would need to be put on the grey port of the airflow switch.

Flow-Through Bypass Humidifier is rated 2.8 out of 5 by 19.
Rated 1 out of 5 by from Honeywell needs to work out problems Water valve would not open. 3/4 of the products online have this problem
Date published: 2016-12-13
Rated 1 out of 5 by from Can't handle the heat On February 17th 2016 this unit was installed on the supply side of my furnace as the instructions stated. Even though the product states it is for older furnaces, it melted parts of the unit and it failed within a couple months use. Unfortunately It was not noticed as we were no longer running the heat until this fall. Now that more than 3 months has past, Home Depot will not warranty it and after contacting Honeywell, tbey have told me they will do absolutely nothing for me. I only gave it a 1 star because it doesn't offer a lower option.

Rated 5 out of 5 by from Great humidifier, good value - preparation & patience are key So far I'm really pleased with the very noticeable over-night increase in humidity ~20% --> ~40%+. I decided to go with this model based on size,price, & features. Install overall took me about 6 hours. Most of that time was watching videos, reviewing instructions & planning! Remember (Measure x 3) = (Cut 1). Get familiar with tin snips! Wiring was easier since I could tap 24V side of furnace control board (R + C) - didn't need to run another 120V line nor use the included trans. Adjust water valve down to minimize excess. I added a 5-year ice-maker type filter on to mitigate sediment build-up. Seal her up good & get ready to breathe easy!!

Rated 1 out of 5 by from Do not buy this humidifier. In fact, I wouldn't even buy any Honeywell products. Their customer... Do not buy this humidifier. In fact, I wouldn't even buy any Honeywell products. Their customer service is atrocious. I purchased one, discovered parts were missing, returned it to the store to find all the others were missing parts but took one home anyway. I then ran around town buying replacement parts. Only when I set to work did I find that the missing parts were hidden within the humidifier itself; wish they would have mentioned that. So I cut a slew of holes in my ductwork, install this second one only to have the solenoid not function after four hours of work. I had to remove the entire thing and exchange it for another one at the store. After installing the third one, the solenoid did work but it would not stay open to let the water through. Honeywell agreed to pay for an HVAC contractor to come take a look. When the contractor arrived he first told me it should not be attached to the supply duct, which is where the directions tell you to install it. He then said the pressure switch (which is supposed to detect moving air then activate the solenoid allowing water to move through) would never work in any scenario. He said the bypass system is poorly designed and in fact, the whole system is poorly designed. Great. He ended up having to rewire the pressure switch to bypass it and wire the humidifier to the furnace. The more I studied the humidifier while the guy was there, the more I realized how poorly designed it is, how it would never work properly and do the job it's intended to do. But does it work? Does it provide humidity? Nope, not really. In fact, it has made no difference at all. Not satisfied, I contacted Honeywell again who gave me the run around for two more weeks before I finally spoke to someone who essentially blamed me for being smart enough to install one but too dumb to find all the information I needed. He said this humidifier is only expected to create 20-28% humidity at best. Why bother? That's what my house is at anyway. I asked him where that information was as I would have liked to have known that beforehand; he stated we don't like to flood customers with too much information or they won't buy the product and take the risk. He blamed me, blamed the store employees, the weather, my furnace might not be the right type, every other variable in the book except his own product. Easy excuse for them -- it's everything else but our product. In the end, the only way to resolve this is either keep the thing, let it drain out and waste a ton of water and do nothing or return it and turn my ductwork into the Bride of Frankenstein by patching a million holes with bits of sheet metal. Did he offer anything? Nope, just a lame apology.

Rated 1 out of 5 by from Don't Do It!!! I recently hired a Contractor to install a humidifier on my furnace. Given the configuration of my furnace, the humidifier had to go on the cold inlet side of the furnace. My Contractor suggested I have him install this model after doing some research and reading that this product can be installed in this configuration. I told him to proceed and he procured the unit from our local Home Depot store and installed the unit relatively easily, but he could not get water to flow to the filter media. After checking and rechecking every fitting, wire connection, and running through all of your trouble shooting tips, he was left without a cause as to why it would not operate. By all appearances the solenoid valve was not working. He called and consulted with one of Honeywell's service representatives on the phone and after a lengthy phone call, and again walking through all the trouble shooting steps, the service rep concluded that the solenoid valve must be faulty. The rep directed him to remove the unit, return it, and reinstall a different one as the remedy. My Contractor did this, and the new unit is suffering from the same malfunction. Again my Contractor spent several hours trying to trouble shoot the problem, verified that all connections have been property made. My Contractor again consulted a Honeywell rep who again concluded that a faulty solenoid must be the cause for the problem. I have now spent $400 in service fees to have the unit installed, uninstalled, and reinstalled, along with several hours of trouble shooting, and it is still inoperable. I did a bit of research on the internet and have come to learn that I am not the only one to experience a faulty solenoid. I filed a request for assistance with Honeywell explaining that I can not continue to fund returning and re-returning this product to the store in hopes that I get one that actually works. 11 days later, I received this utterly worthless response: "Please be advised that the limited retail product warranty that accompanies your HE240 Retail Humidifier is limited to receiving a warranty exchange or refund on a defective unit directly through the retailer where the product was purchased upon return of the unit in question together with proof of purchase. However, the decision to enlist the services of a professional contractor for assistance before, during, or after the install of the retail product shall be done at the sole discretion of the retail consumer irrespective of any potential product defect situation. Paul Arntzen Honeywell Customer Care Lead" Honeywell clearly has no confidence in their product and offers their customers no remedy for having purchased one (in my case, two) of their defective products. I strongly urge any potential buyers to pursue another, more reliable brand.

Rated 4 out of 5 by from Honeywell Humidifier I bought this humidifier at the recommendation of my HVAC servicer (who installed it on my furnace). Prior in house humidity ranged 15 - 22%. After installation it has ranged 24 - 32%; even at the highest setting. I had hoped to get it into the 40 - 45% range because of a dry eye condition my wife has. So far it hasn't made it after 30 days.
