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
Asked by

Read all my Q&A
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.

George

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.

Rated 3.0 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by 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!! December 4, 2012
Rated 4.0 out of 5.0 by 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. March 29, 2016
Rated 1.0 out of 5.0 by Useless I have a new , energy efficient 2000 sq ft house and I set the humidifier to 40% , but if is unable to keep up, especially when it is cold outside . It is waiting water , looks like 2 buckets of water a day are going to the drain. Will definitely return February 23, 2016
Rated 2.0 out of 5.0 by Obsolete I was amazed that the solenoid froze after 3 years and to my surprise this unit is obsolete. I have searched online for a replacement solenoid (DC24 volt) for the HE 240 to no avail. I can't figure out how they are still selling the humidifier. January 18, 2016
Rated 1.0 out of 5.0 by Not Happy After one winter the valve does not work any more. Not going to replace it due to the fear of having to replace it again next winter. Going with a different model. December 23, 2015
Rated 1.0 out of 5.0 by Installation is a hassle, output is poor. Pain to install. Supplied hardware doesn't grip the sheet metal very well. It is level and sealed to the supply duct but output disappointing. 2600 sq ft, 10 year old home and still need to use portable units to get humidity above 30%. Definitely not worth the cost, especially if you need to install power nearby and buy sheet metal tools to install it. December 31, 2014
Rated 5.0 out of 5.0 by Good product, easy install During the winter months my house has had very low humidity that drops as low as 22%. Humidity this low causes uncomfortably dry skin and static electricity (I was getting shocked every time I touched a light switch). I did some research and found this to be the best value solution. The humidifier comes with everything you need for the install (minus the tools) and even foil tape was included. There's a handy YouTube video by Honeywell that helps with the installation, although it took me 4 hours instead of the 1 hour they claim in the video and I consider myself handy. I have two furnaces (one in the attic and one in the basement) for my house which is approximately 3000 sq ft. I installed the humidifier above the A/C chiller box on the supply side on the basement unit because the attic has no easily accessible water supply. I have the humidistat set on 40%, but the humidity in the house doesn't seem to go above 35-38%. This is probably because the furnace is sized for half house so the air flow isn't sufficient to draw enough moisture into the air to get the humidity up for the whole house. Overall, I'm happy with the purchase and getting the humidity 10-15% higher in the house has made it much more comfortable. February 3, 2015
Rated 1.0 out of 5.0 by Honeywell HE 280 humidifier I purchased the Honeywell H 280 humidifier and after 2 seasons the solenoid broke and I have to pay about half of the original price for a new solenoid. November 17, 2014
