Furnace Humidifiers?

9 posts in this topic

With the upcoming winter season approaching, I have been thinking about installing a humidifier attached to the furnace. I know last year we had a couple table top units that were not able to keep up. The house was still dry.

I'm wondering if this is a good idea or should I purchase a larger stand-alone humidifier? My biggest concern is mold. I have always been told that you want a cool mist in the winter and with installing one attached to the furnace would this now be a warm mist?

Thanks for the replies in advance!

Get a furnace mount. They all work pretty well. Get one that YOU can get the

panels. That way you don't have to keep going back to a service teck to get them.

Change the panel once a year, in the fall. VERY IMPORTANT

DO NOT buy a Humidifier that has a wheel in it. (JUNK)

Warm air will absorb lots of humidity. Cold air will not.

Who ever told about a cool mist vs. warm mist doesn't know what they are talking

about. You want to evaporate the moisture in to the air. Not squirt water/mist in

the air-stream (very bad)

Last. If your furnace only runs a couple of times an hour (tight house) in the winter,

You may wont to keep your stand alone units as well.

A furnace Hun. only works when the furnace is running.

A whole house humidifier is a good thing but they also will plug up alot and can be somewhat of a hassle especially if you have hard water. Also it is a GOOD idea to tap into the hot water. IMO a great unit is a Aprilaire you can find them on hsolist. Better tthan that would be a residental steam humid. about three time the price but the maintenece is none and they dont leak plus it is a much cleaner install.

I don't see the advantage of tapping into the hot water line. The flow rate used is so small that the water won't be hot by the time it gets to the furnace anyway. Also, using the hot water line encourages bacterial growth in the humidifier that you may not want.

Mine works great. It has filter cartridges that can be replaced once a year and includes a humidstat to regulate the humidity in the house, which is very important.

One advantage to using a humidifies is that it can save you a lot on your heating bill. You'll find the house will be more comfortable at lower temperatures.

My Aprilaire was tapped into the hot water line when I bought my house. I've never had any issues as long as I put in a new cartridge every fall.

I just had a quote done and they want $750.00 installed for a unit with it's own blower. They said I would need a blower for the size of the house.

Any comments on the price? Good/Bad?

I'm willing to learn/install things myself, but with plumbing I'm not comfortable.

Thanks for the info~

If you have a forced air furnace I don't see why you'd have to have a separate blower. I would think you could find one that could be installed on your existing ductwork. I installed my own on my cold air return plenum in my basement. Only tools required was a tin shears and drill to punch a hole. The plumbing was a 1/4" plastic tube with a copper piercing adaptor that clamped onto my water line and punched its own hole. The electrical was just to hook up 120v to the unit to power a solenoid valve controlled by the humidstat. Mine is a Skuttle flow-through model 2001 if you're interested in seeing what I'm talking about.

I would not use one of the vampire clips (piercing saddle) a mess waiting to happen and not legal. I am sure alot of people have had no problems with the ones they use but i have seen plenty that have caused problems. Instead cut in a tee and use an angle stop (just like you have under your lav) then any time you need to shut the water off its no problem and it will meet code.

Not legal? I'm not aware of this.

    • License what technology, this kind?        https://www.google.com/amp/www.cnbc.com/amp/2017/04/27/after-vws-record-fine-mercedes-benz-parent-daimler-could-be-next.html     "In light of the ongoing governmental information requests, inquiries and investigations, and our own internal investigation, it cannot be ruled out that the authorities might reach the conclusion that Mercedes-Benz diesel vehicles have similar functionalities," Daimler said in its newly released quarterly report. The maker first acknowledged in January that authorities had begun probing its handling of diesel emissions. That was the same month that VW agreed to settle a criminal probe by the U.S. Justice Department, a federal judge this past week approving the payment of a $2.8 billion fine. Almost 40 times the legal limit In the VW case, the mainstream German automaker rigged the software controlling two diesel engines to recognize when a vehicle was undergoing emissions tests and then adjust pollution levels. In real-world situations, the U.S. Environmental Protection Agency asserted, those powerplants would produce up to 40 times the legal limit for pollutants like smog-causing oxides of nitrogen. Since the scandal broke in September 2015, regulators in the U.S. and the European Union have begun rechecking the emissions claims made by other manufacturers, including Daimler, General Motors, Fiat Chrysler Automobiles and others. In January of this year, the EPA took aim at FCA, alleging that it may have used its own, rigged software on products like the Ram 1500 EcoDiesel which "appeared to cause the vehicles to perform differently when being tested" than when in use in real-world conditions. That same month, Daimler said that what the EPA was concerned about "apparently includ(ed) functionalities that are common in diesel vehicles, as undisclosed Auxiliary Emission Control Devices (AECD)." While the German parent of both the Mercedes-Benz and Smart brands did not confirm it had broken the law, it laid open the possibility that its own diesel emissions strategy could be in trouble. "If these or other inquiries, investigations, legal actions and/or proceedings result in unfavorable findings, an unfavorable outcome or otherwise develop unfavorably, Daimler could be subject to significant monetary penalties, remediation requirements, vehicle recalls, process improvements and mitigation measures," Daimler stated.
    •   Wow, Del I forgot all about that little discussion you started two years ago.  All the fun folks were in on it, even the LIMITOUT. That's what happens when you have short term memory loss and and pictures bring on new thoughts and emotions.  Let's just call this threat the "What a dang waste and shame!" More of an aftermath threat?  K
    • When we had are seasonal campsite I had lots of squirrels. I used all metal feeders. Come Sept them squirrels went in the freezer and cooked up for the wild game feed!
    • If you have been following the story, the reason VW got in this mess is they didn't want to license technology from BMW (or maybe Mercedes) and chose to develop their own.   When it couldn't be made to work properly, they chose to cheat rather than bite the bullet.    Long discussions of what happened as the story broke    
    • I had one of those.  Mine never quite ran right, although I lived with the quirks for years.  I have a pdf of service manual if you want it.   Mine ran rough intermittently at certain rpm.
    • If they make it better because of stupid government mandates it wouldn't bother me at all.   In fact, the Dodge ram diesel that I used to have had something from Daimler Benz that allowed it to meet the standards without DEF. I would not be surprised if they did something similar with those diesels and if they did I applaud them. The best thing anyone can do with the diesel trucks is delete the emissions and unlock the power and economy that are robbed from them.   
    • pellet gun does the job here  
    • I have to many squirrels, need the feeders with the metal holes.
    • build it and they will come.
