We heat primarily with a wood stove at the base of our stairway in an open-floorplan house, and the heat distributes quite well without fans. However, at night we like to keep the kids bedroom doors closed, and I'd like to install fans through their walls to circulate heat better at night.
I've found a purpose-made through-wall fan unit, but it's got white plastic grates, and it looks a little institutional. We'd prefer to put some nice wood grates over the fans, so I'm looking at coming up with my own solution.
I'm planning to use an in-line duct booster fan, and I'm wondering if anyone can recommend the quietest model. Also, I'd like to wire it to a controller or dimmer so I can control the fan speed. Is that possible with these fans?
I'll just fit these through the stud wall, and cover each side with a nice-looking grate.
You may not need heat if you run them on a dimmer to slow for long they will cause a nice fire on their own. You really need to get a fan made to be multi speed for this type of install. I'm sure if you google wood heating sites you will find a fan made for what you have in mind.
