Not really sure what is going on, but my pdvc is eating pellets like crazy, no matter the setting. I have a tstat on it, I usually set the stove at 9//9. I set my tstat to 75, which is only about 5 ft away from the stove. I usually fill the stove up at around 10 pm, I get up around 5 am and the hopper is over 3/4 empty. Last night I fired up my other stove ( ef2) and ran both over night. So I know the temp did not drop below 75, so the tstat is not calling for heat. but yet once again the pdvc hopper is 3/4 gone. The stove was extensively cleaned over the summer. I have only been using barefoots and dry creek premiums. Also the window gets very dirty quickly. With my EF2, I can go almost a full day on a bag of pellets. IDK what is going on, but I don't likey.
