Product review (5 stars): Works as advertised
I was tired of the usual dry air in the house during Winter and the static shocks associated with it. Furthermore, the stand alone humidifier was a pain in the neck to always fill with water and clean and it wasn't up to the task of making the house comfortable anyway! So I looked into the whole house humidifier. I originally purchased a different whole house humidifier but I found out that there just wasn't enough room on the furnace to mount it. I did more research and found the TrueSteam humidifier could be mounted up to 10 feet away from the furnace (20 feet with optional accessory) so I went with the largest unit (the 12 gallon) with the true IAQ control. It included everything needed to set up the humidifier, including a very nice thermostat/humidistat unit. I got the largest unit because I wanted to make sure I had adequate supply of moisture. I have about 2500 square feet of space to humidify and the house is  fairly old.

I'm just a regular do it yourselfer with no training in HVAC systems so I was a little nervous about setting the system up myself. It was not too difficult though. The humidifier itself was fairly easy to set up. As they say, you only have to drill a hole into the supply side of the furnace. Tapping into the water line was easy. Switching out the thermostat was not too bad but it did require running a new set of wires which ended up being the most difficult part of the process. Then it was just a matter of figuring out which wires connect to where. I made sure I understood how my old heat pump thermostat was wired before I started and the wiring ended up being easy to deal with also.

Unfortunately, when I started up the system something was wrong. After a lot of troubleshooting, I figured out the TrueSteam unit did not work! I contacted the company and they sent out a new one right away and paid for return shipping. Then I simply substituted the new one for the old one and it worked great!

I have gone through a whole Winter season now. The new thermostat allows for fine tuning the humidity to your house to prevent condensation on your windows. All that works great. The house was very comfortable the whole Winter. No electric shocks! No more dry sinuses!

A very nice feature of the unit is that it drains water from the tank when it's not being used to help keep the tank clean. I just did my post season tank cleaning and I did find sediments at the bottom of the tank. They were easy to rinse out. Now my unit is ready for next Winter!
