Incredible addition to our home!I just installed this beast in the 83 year old home we bought and it has been incredibly beneficial...and we just installed it 24 hours ago! Our home is not tight at all (a project for another time) and my wife and two year old twins were hurting a little from the Wisconsin winter.I had some help from a buddy to install as I'm challenged when it comes to this type of thing and it took about 4 hours total which included a 40 minutes round trip to Home Depot for the parts. I know a lot of people use metal sheet clippers to cut the hole and that might have been easier. We used a Sawzall for most and a Dremel to get the cuts started. The online videos and tutorials were great and made it easy.We have the drain tube running into a ClearVue [...] which was clogged so we had a little overflow initially but once we discovered the clog and got it going, it is working perfectly. I'm not sure if it is designed to run so often but it really works well and I would like to keep this process in place rather than running a new drain line along the wall.Another feature I like about the Aprilaire 700 is that it pumps humidity through the house without the furnace running. While there is a "Blower Activation" option which activates the HVAC fan for maximum humidification, it's not required. It states it in the manual, but the first 24-48 hours seems to be about finding the happy medium and adjustments. We woke up this morning with a small amount of condensation on a few windows and adjusted accordingly.This is my first house and it's my first whole-house humidifier...it's a noticeable difference from your breathing to your skin. 5Exactly what the house needed with a new baby on the way!Spent many hours researching how to install a whole house humidifier and this one was recommended many times. When our furnace got serviced this fall the technician also recommended we get a humidifier and when I asked him which model this is the one he recommended. It's really hard to find anyone selling this unit because the manufacturer doesn't want just anyone to install it, they recommend a technician so I was pretty happy when I found it here on Amazon.After doing some research and a couple times watching this video on youtube([...]) I decided to take the project on myself. It actually was a lot easier than I had expected. Aprilaire's instructions were pretty easy to follow and the automatic digital control gives you a great display in case an error code comes up.If you are good at following instructions, and have some confidence you can save yourself around $300-$500 on the installation cost I was quoted from 4 different HVAC companies. I was able to complete the project in 3 hours. Another friend of mine installed the same unit in his house and he took just about the same amount of time, he might have been closer to 4 hours. So in 3-4 hours you will be sitting back enjoying the new humidifier.Things You Will Need To Install Yourself:* 3/4" PVC pipe (optional, i used it to run the 1/2" tubing into to continue to the drain instead of running the tubing all the way, I split into the same 3/4" coming out of the furnace)* 1/4" copper tubing to run the hot water into the humidifier* 1/2" plastic tubing to drain the water* Sawzall or equivalent tool to cut sheet metal* Low-Voltage wiring to wire the thermostat and thermometer (i bought 2 of these Coleman Cable 09631 CL2 Bulk Thermostat Cable, 18-Gauge 2-Conductor 50-Feet)* 2 Electrical - Terminals for the wiring* Some wiring caps (medium size)* Foil Tape (I bought 3M 3311-50 Scotch Foil Tape, 2-Inch-by-50-Yard)* Pipe Cutter (I bought Ridgid 40617 1/4-Inch to 1-1/8-Inch Close Quarters Tubing Cutter)* Permanent marker* LevelIt's been running for over a month now and I was able to notice a difference immediately. I even have a gauge on the second floor that measures humidity and it's constantly has the correct amount of humidity in the house. I'm very happy with this purchase and highly recommend it to anyone in the market. 5Installed with no difficulty; many configuration options make this fairly flexible, but requires careful analysis before buyingThanks to the many excellent reviews by other Amazon buyers of this unit, I was alerted to the various potential difficulties, and was able to plan and execute a successful installation with no unexpected problems. I must highly recommend that anyone considering this product carefully read the most helpful reviews, including several of the critical ones, in order to be informed enough to make a good decision on both buying and installing this product, because it's fairly sophisticated in its capabilities and can be complicated to plan the installation.It's been in operation for about a week, and it appears to work as hoped. My one small complaint at the moment is that its highest setting is 45% RH - it can't be set to deliver more humidity than that. In my installation, I would like to have 50% RH. This could be accomplished by using an independent humidistat, such as those in some of the smart thermostats like Ecobee3, Nest, and others, to control the humidifier instead of the Aprilaire digital controller. In that case, you would lose the Aprilaire's ability to automatically adjust the setting depending on outside temperature. This is not a big concern for me, so I'll probably end up rewiring my system to use my Ecobee3, which would give the added convenience of being able to control humidity from my phone or anywhere on the Internet.If I encounter any of the problems that some folks have reported, such as inability to deliver the selected humidity, or anything else, I'll come back and update this review.------------------------Update dec 15, 2016:A month after we had it installed, the RH in the house finally dropped low enough for the humidifier to turn on - it came on at 42% and shut off when it had raised the RH to 45%. This is acceptable, although, as previously mentioned, I would've liked to set 50%, and would like it to come on at closer to the set point (e.g., 43% if set for 45%). But it does work well, and raised the RH of a somewhat porous 2000 sq ft house in under 10 minutes.Here's what I don't like:* As others have said, it wastes quite a bit of water (not a problem for us, but not very efficient if you live in a drought area).* Doesn't go over 45% (already mentioned).* Requires a nearby drain or a sump pump to get rid of the waste water.Fortunately for me, none of these were critical problems, and it does a very good job. I luckily haven't had any of the problems that others have reported, but I'm very grateful that so many reviews provided important installation tips (e.g., tape around the opening to prevent air leak and noise, etc.). 5System works good, but has flaws.This unit was easy to put in and the directions where simple enough to understand and follow. Make sure of what type of install you will make because not everything comes with the product. I had to make several trips to the store. As for how the unit works, I think its fine. I have a large 3800 sq ft house and it keeps the house at about 45% when the outside temp is between 10-40 degrees F. When it gets colder, between minus 30-10 the unit struggles to keep up and the house is around 30% humidity. So the issues I have are not major, but for the cost of the unit they need to be addressed. If the unit is on and running, the water is running, constantly. There is an overflow that needs to be plumbed into a drain, and the water is not regulated. It just flows through the unit and out down the drain. The other problem I had was after installing the unit drew so much air through it, that it whistled. Annoyingly loud all the time! I contacted the company and they where aware of the issue, but were no help is resolving the problem. To fix it, I had to tape all the seams where the air was leaking both inside and out of the unit. It was a little frustrating to resolve and even more so to know that the company knows about this issue and was no help. 2DisappointedHas been running constantly for a week with and without the furnace with very little increase in humidity. My hygrometer typically reads ~20% without humidifier and stays there when only running humidifier with furnace. If I let it run without furnace as well, it ll get up to ~30%. This is in a 2,300 sqft home, nowhere near the 4,000 it claims to be rated for. I do find the units humidity reading is typically 10% higher than actual room humidity, so maybe it s kicking it off with a false high reading even at the highest setting. Professional installation on return air with hot water. 1Very effective. Easy install.What a difference! This thing should come standard on a furnace install. The install was extremely easy. If you have a basic understanding of electrical system schematics, the install will be very basic. Make sure you get a roll of 18/5 wire long enough to run your wires from the main unit to the control panel and the furnace connection. You will need enough to run another line from the control panel to the furnace connection. When mounting the control panel, keep in mind the temperature sensor only has a 3' cable to attach it to the control panel. The 1/2" clear tubing is another thing you will need. Make sure you have somewhere for the water to go. The water does not just drip out, it is a fair little stream that runs constantly while the unit is in operation. I suggest watching several videos available on line.As far as effectiveness, it took about a day and a half to notice the difference. BUT WHAT A DIFFERENCE!! I can't believe I waited all these years to buy a humidifier unit. 5Easy to install but humidity increase marginalEverything arrived intact and relatively fast - easy to install. I live in Colorado and this unit boosted my indoor humidity (3800 sq. ft. house, cold water tap, only when furnace was ON) from the high teens to approx. 30%. I only gave it 4 stars for two reasons, 1) it was difficult to get a solid attachment to the sheet metal ductwork for all mounting holes for the unit (hole cutout perimeter for unit is too close to mounting hole locations) and 2) I also was expecting a wall plug 24 VAC transformer instead of the hard-wired metal-box type of mounting one I received. Had to spend an additional $15 on a 24 VAC wall plug unit for sprinkler system from LOWES vs. having to add a metal outlet box and the associated wiring. I plan to try hot water supply by adding a shark bite Tee/w 1/4" shutoff valve to my hot water line to see how much increased humidity I can obtain by using hot water vs cold. 4Very Efficient & Well Made Unit & Integrates Seamlessly with NESTFirst off, I would like to thank all the reviewers on Amazon that took the time to write a review on this unit. It's folks like you that put other folks that are interested in a product at ease by well written, detailed reviews; so I am going to return the favor for other potential buyers of this unit.I have a vacation home in rural Northwest Montana where the winters are cold and the heat needs to run in order to keep the house maintained. But, running the heat all winter lowered the humidity in my home to the mid teens and it was starting to have an effect on the house itself with cracked logs, squeaky floors, dry skin, sore throat... I started my research on Amazon for a whole home humidifier and kept getting drawn back to the Aprilaire 700. It had a TON of positive reviews and tons of information about installing it with a NEST as the controller, which was what I was trying to do myself.I finally convinced myself that this was the unit for me and ordered one, along with everything that I would need for the installation - SharkBite fittings, copper tubing, PEX and although not mandatory, a hot water filter system to remove sediment from my well water before it got to the humidifier.I am a contractor by trade so installation came easy for me. I simply used the template that came with the unit to outline the hole I needed to cut, leveled it off and then cut it out. I opted to install the humidifier in the supply duct using hot water as I read that this was the best way to increase humidity levels when the unit was operating. The unit fit right into the cutout and secured with 2 rotating locks that hold it against the inside of the duct work. I had a standard outlet right next to my HVAC unit, to all I had to do was plug it in. I did use HVAC tape to seal all the edges around the outside of the humidifier unit as a precaution against escaping warm air but if you make the hole the correct size, you shouldn't have any gap at all.My plan all along was to use my Gen3 NEST to act as the humidistat and again, thanks to all the reviews, it was a very easy affair to make the connections from the humidifier to the NEST. My HVAC system consists of a heat pump heating system with emergency heat and heat pump cooling as well. I had 8 wires running from the thermostat down to the HVAC unit and I was only using 6 of them, so I had 2 spares. The humidifier only needed one wire from the NEST in order to make it work.You will see a bunch of reviews that state the need for a transformer and relays... None of that is required. You simply need one wire from your NEST * terminal down to one wire on the humidifier solenoid and the other wire from the solenoid connected to the C terminal on your HVAC low voltage control board. That's it. If your HVAC control board is not clearly labeled, you can test it with a voltmeter to be sure. You are looking for the terminal that supplies +24V when the heat/fan come on.After making all the electrical connections, I turned to the plumbing. Because I am on a well system, I decided to install a hot water filter between the hot water main leaving the hot water heater and the humidifier. I ordered a KleenWater hot water sediment filter system which worked excellent. I installed a standard shut off valve ahead of the filter and then reduced the filter down to 1/4" copper tubing which then routes over to the humidifier.The way I have my NEST programmed is to run the humidifier when the heat turns on (more on this later). When the temperature in the house drops, the heat kicks on and the humidifier turns on at the same time. The humidifier works by drawing water into a filter pad which a fan blows on and forces the moist air into the warm supply air of the furnace and then into your home. When the fan/heat turn on, a signal is sent to the humidifier solenoid that opens it up and allows water to flow across the filter pad. Excess water pools into a small catch drain at the bottom of the unit and then runs out the drain tube into a suitable drain or condensate drain.My first concern with operating the unit was the steady trickle of water flowing out of the drain. For fun, I inserted a needle valve prior to the unit in an attempt to better regulate water flow coming into the unit and thereby reducing the overall waste water flow. What I realized afterwards is that the solenoid has a reducing fitting inside it that regulates the incoming water flow so I am not entirely convinced that the needle valve is needed. In fact, if I pinched down too much on the flow, it wasn't enough pressure to get the water flowing again when the unit started up. By playing with the valve and observing, I was able to achieve a nice balanced situation with incoming water and waste water. (I am on a well system so I don't pay for water, but it did bug me that hot water was just running down the drain). Do keep in mind that there will be waste water no matter what you do. It's the design of the unit to work this way.With regard to setting up your NEST, you have 2 options. The first is to run the humidifier when the heat kicks on only. This is the most energy efficient setting overall and creates the least amount of water use. The second option is to have your NEST act as the humidistat controller for the unit and set a target humidity level for it to reach. This uses the most amount of water and will humidify your home with or without heat on.I initially thought I would use the unit in the 2nd mode, but quickly realized that it was just going to run and run and run until it reached a pre-set humidity level. In the end, I opted for the 1st mode instead and simply had the unit kick on when the heat does. Coincidentally, this is the most efficient way to increase the humidity levels in your home. The hot water together with the warm air compound the ability for the humidifier to do its job.Navigating the NEST menus is pretty straight-forward. You will need to tell it that you are using a humidifier on the * terminal and then set it to work with heat or as a standalone humidifier. Some of those settings are in the "Pro" menus which NEST makes a big deal about, but just take your time and think about what you are doing before you do it.Overall, I couldn't be happier with the unit. It's quiet and very efficient. On the first night of installation, I had my thermostat set to 68. After the wood burning stove died out, the heat kicked on around 4 AM. Between 4 AM and 6 AM, the relative humidity level in my home went from 20 to a staggering 35 percent prior to the heater reaching 68 degrees and shutting off. In the first week since installation, I have hit 38% humidity levels in my home, but keep in mind that it only humidifies when my heater is running and most of the time I use my wood burning stove to heat the house. If you feel that you need more humidity but no heat, just change the settings in the NEST again and use it like a standard humidistat.A couple of final notes... If you are going to use your NEST to control the unit, and I don't know why you wouldn't, you don't need to order the Aprilaire with a humidistat. That will save you some $$$.I am going to run a test next week and capture the water run off in a 5 gallon bucket and measure it over an hours time to see how much is really draining off the unit. If it's 5 gallons an hour or less, I would be OK with those numbers. More to come on that.Other than that, if you are in the market for a hole home humidifier and are a little bit handy with plumbing and low voltage electrical wiring, installation of this unit is fairly easy and straightforward.Hopefully this review helps and once again, thank you to all the other reviewers of this product. 5Works Great!This works great! Just keep in mind that if it's installed on the cold air return side of your air handler, you must provide HOT to the unit. This means that for those that have a tankless water heater, you'll need to provide another source of hot water as the humidifier won't draw enough water to turn your tankless on. I even tried a mini-tankless described as low flow (0.5 GPM) and that didn't work.A different choice of humidifier is the Aprilaire 800 which is a steam generator. That had too much capacity and uses too much power for me. The 700 is perfect. 5Worth the moneyI wouldn't say that self install is for everyone but if you choose to do so its not terribly difficult. You will need to buy stat line and flexible copper piping. The unit comes with a piercing valve but I would advise against actually using it. Yes this will make the job more difficult but using a traditional ball valve is much more reliable. I would also recommend using the outdoor air sensor. This will cause possible static electricity which is a lot of reason why people are getting this to begin with but this typically only happened when it is extremely cold outside. If you allow it to operate at normal levels when it is extremely cold out you will get condensate on your windows. Now if you wish you can go down and turn it down every time its 20 degrees or less but if you have the sensor installed you wont have to deal with that. I'm on season 2 of using this after installing hardwood floors and have had no issues with the unit. It requires very little maintenance outside of a filter change and once you have determined the proper setting on the humidistat you can pretty much forget it exist. I installed mine in about 90 minutes but in fairness I work HVAC for a living and have all the tools to make this an easy install so I might double that time if your not use to doing these kinds of things but somebody who is relatively mechanically inclined should have no issues installing this if you follow the directions and have some basic tools. The most important thing would be the ability to cut metal as you will need to cut the duct to install this on the supply side above your furnace usually. 5
