More on the whole-house humidifier

Checked out the whole-house humidifier system at home. We have a Frigidaire Power Humidifier. It's a nice system in that it basically regulates itself based on temperature and relative humidity. It only runs when it needs to and you really don't have to screw with the system. You set the humidistat in the percentage range you want and then the system figures out when it needs to run based on the air temperature and humidity in the ductwork to keep the relative humidity where it needs to be. The Power Humidifier is better at dispersing the humidity into the system, and because it regulates itself, it's not throwing gross amounts of moisture into the ductwork all the time. And you really don't have to babysit it.

Also the house is single floor sitting on a full basement so a single return which is central in location does make good sense and the house has excellent airflow. ...
... I asked around with several people in the industry and they told me if its set up correctly and everything figured properly this is a very efficient set up depending on house design.

Sounds great until you want to have heat in a room with a closed door. Once you close a door you will be getting a greatly reduced flow of heated air to that room. It's as if you restricted the vent to the size of the crack around the door frame.

A simple solution is to leave the doors open when you are in a room (even an inch is suffcient), install louvers or a small through vent that would allow airflow to the central return.

Efficient can mean different things. Uses less metal duct and associated man hours - Yes. Gets the heat to each room evenly - Not so much.
