Hello I just purchased a breckwell big e second hand. I had the stove installed with a stright out the wall exhaust and a cap. My house is 900Sq feet downstairs and 400SQ feet upstairs. The stove is in the famly room. I have no halls and my stairs are center in the house its very open. In the room the stove is in on setting 4 its 73 and the next room over is 71 and the kitchen is 64. I purchased this in a hurry as our oil tank got a leak and needed to be replaced. It was cleaned good before the install behind the plates and everything. The previous owner only used 1 ton before replaceing it with a smaller one they said this was way to big. I have messed with the damper to no end. Am I missing something? This was suposed to heat our whole house and it barley heats 2 rooms on 4 to 70. Its 35 outside as I post this. My house in insulated good. Any help would be great. (I searched previos posts and I do not have baffle plates)
