We install close to 1000 of the 12 and 17 gallon models every year.  I can count on one hand the amount of times I've had to fix one over the last five years.

They come with an upgraded plastic water line approved for both hot and cold water so you don't have to waste money on copper if you use hot water.  The installation manual also says the humidistat only needs to be 6 inches above the humidifier which is a lot less than other brands and makes tight installs easier.

Hot will evaporate faster.  It won't work on hot if there is a tankless water heater and I don't like storage type tanks due to the possibility of bacteria.  That's why it's best to just install the right size humidifier and use cold water.  It should only activate with heating and the hot air will evaporate the cold water.

I tee into existing drain lines all the time.

The saddle valve that comes with the humidifier is approved to be installed on PEX, it's just illegal according to the Ontario Building Code.  I would crimp in a tee and use a 1/4" shut off valve, or use a Sharkbite fitting.

The HCWB3-12K part #Y3681 is more than large enough.

You should have no problems if you go with the larger model.  The water bill may be a little higher though.

Thats the return line from the air handler is it ok to add the valve there and or will it affect the system?

Where I wanna mount it is 12 " wide.  Manual days its 12 7/8 wide, but is that just the exterior cover any idea how wide the mounting plate is ?
