I have a New England Summer's Heat 3000 add on woodstove, after the start up, then the intial burn, when i get to the secondary burn the temparture in the flue drop's between 300 degree's & 250 degree's. It only goes back up to 500 degree's if you restock. So after the intial burn i only get about an 1hr 1/2 in the good burn zone then right into the creosote zone .It usually hang's right around 300 degree's, I'm thinking it's because the blower never shuts off, and pull's the heat out of the flue. The blower motor kick's on at 125 degree's, and off at 95 degree's, so pretty much after it i start it kick's on. Anybody with any experience with these that knows how to keep the heat in the flue would be greatly appreciated.. Started using this stove in begining of january, already have to sweep the chimmney out.
