The instructions actually say to have a professional install the humidifier, but I watched a lot of You Tube instructional videos and since I have a moderate ability with things like this, I did it myself. (If you can put on a slip on SharkBite connector, you can do this). One thing I cannot praise enough is SharkBite connectors, which I used for a secure tap into my cold water line. Their slip on (no solder) copper pipe connectors are amazing.
Also, I'd really consider the NEST as your controller. The Aprilaire 700 (Automatic) came with a fancy controller that has a wired outdoor thermometer that reports outdoor temp to the controller so it can intelligently drop humidity setting when it gets colder to below the condensation level (for your windows). That sounds great and I thought I'd miss not having that feature but unless you live in a region with crazy temp swings (In Virginia, we do not) then you don't need it. The NEST, though it knows the temp outside for your area), does not yet factor that into any intelligent humidity adjustment (though it easily could later if they wanted to push an update). For now the NEST humidity setting is "set it and forget it". If you plan to use the NEST thermostat as your controller, buy the Aprilaire 700m as the “m” (manual) version is about fifty dollars less because it doesn’t include the Aprilaire controller (which would not be used if you were to use the NEST in its place).
The wiring can be tricky and they try hard to prevent homeowners from installing it themselves. I had to dig around online to find documentation from NEST on how to integrate the Aprilaire 700 with their thermostat. I found a NEST Contractor manual online and that showed me the way. It all came together when I realized my Aprilaire 700 needs 24 VAC on its two brown wires (and not a separate relay like I had originally thought). As a reality check, I spent several days reading forums, printing out directions, and running back and forth to Home Depot (including one run to get Aviator Snips to make the hole for the humidifier in the HVAC Supply duct), before doing the install.
If your tap water isn’t too hard or if you don't mind adding a water filter in-line, you may want to consider a steam humidifier. Here are the economics: Flow Through type humidifiers like the Aprilaire 700 (when on) pass 1 gallon every ten minutes (I’ve read that and measured it myself), or 6 gal per hour. If (this is upper bound max) it ran 24/7 for a month, the Aprilaire 700 could use 4,300 gallons in a month. For every 1,000 gallon it costs me approximately $6, so figure the MAX cost at ~$25/month x 4 months =$100 for water. Flow through filters take no maintenance other than annual replacement, so figure that in too. All in all, I expect my costs will be less than Max (as the humidifier does occasionally shut off with humidity set at 40%), and I'm ok with the price point to avoid crazy dry skin. Steam is supposed to be a faster delivery mechanism (and even more efficient), but water line filter costs would likely exceed water cost of the flow through (if you needed to install filtration upstream of the humidifier). Since my water isn’t very mineralized, if I had it to do over again I would try a steam humidifier, but the Aprilaire 700 does the job fine.
Today, I got the place up to 50 percent relative humidity today while we were out and my fiancé could smell a faint odor of chlorine upon our return (In Fairfax, Virginia they heavily shocks the water with chlorine). Dialing back the humidity a little seemed to clear that up. If any chlorine odor returns, my next step may have to be either a humidifier line water filter, or perhaps a whole home water filter. But that has nothing to do with the humidifier and I only mention it for completeness. To close: The Aprilaire 700 (manual version preferred) connected to the NEST thermostat delivers long sought after humidity levels in my home and I only wish I had installed it years ago. Cheers and good luck to you! – Terry H (Fairfax, Va)
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
It'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.
