Thanks Mac. I appreciate your input.
To be honest, my knowledge of pellet stoves on January 1st was right up there with my knowledge on astrophysics.

I assumed that a unit that was "rated" for 1500 sq/ft would heat up my addition (VERY well insulated by NCI here in OH) and have a lot left to flow elsewhere. I found this forum about 10 days too late. I think that as I have more time to tinker with my PDVC I will be very happy with what I can obtain. I'm not afraid to burn 2 bags a day when I get them for the right price. Having a late start this season has left me in experimentation mode. I'm familiar with switching the PDVC to mode "C" for additional heat output, that seems to have cured issues for a lot of owners. For me, I'm not ready sacrifice the extra pellet burn just yet, I've only been burning for a week and I've not yet run the stove higher than 6-7.
Tonight is one of the coldest nights so far this year here in Ohio. Wind chill right around 0*F. My wife started the stove at 8PM when she got home and ran it on 3-3 til 10:30PM. She went to bed an set it on 1-1 and closed the addition doors. I just got home and the temp out there is 73*F and very comfortable. The stove has no prob heating the room adequately. What happens when I open up the addition and attempt to heat a portion of my house is still being tested, but I see your point about a bigger unit. There are a lot of owners who use these as a sole source of heat in 1000+ sq/ft dwelling from what I've read. I plan to use my in tandem with my furnace set to a reduced temp on most months and see what I get. I'm excited to keep experimenting.
I can't believe how much I enjoy the look and feel of the stove. I would have invested a long time ago had I known how much we would enjoy it. I plan on owning these unit(s) for a long time as I continue to educate myself. A bigger stove is prob not too far in my future. My existing PDVC would look great in the detached garage!
