Heating Update,
As a refresh I recently built a 16 foot yurt in Reno NV, and now we are in the 20's at night. As it is a backyard yurt I opted for a 120v Inverter, and selected this:

It has been flawless, and was easy to install and set up. It is extremely quiet, and occasionally I can hear the fan very faintly outside of the yurt but the inside unit is silent even when fully on. I imagine you could soundproof the unit to some degree, but it is not really noticeable.
As for heat: It heats the space uniformly and will easily hold any temp I set. I currently have it set at 77 degree's and it maintains a heat at floor level of about 73 degrees. I believe the energy usage to be minimal as it is such a hyper efficient unit, my guess would be $50-75 a month based on live meter usage but I will know more in a few weeks and will post costs.
I leave it on 24x7 and it usually kicks on and off less throughout the day as the sun heats up the Yurt. All in all, I am thrilled. It's not cheap, but honestly I can't really deal with the heating with wood concept, and need my Yurt warm and ready at all times for work or guests.
Our first guests have raved about it. I thought the price was right, and is plenty warm for any climate, and has the benefit of cooling as well. You will need a 100$ vacuum pump to install the unit, but was easy to do, with many youtube videos to support the process.
Cheers, Happy to answer any and all questions.
