We are in a half double, 1400 sq. ft, but it is laid out unlike a traditional half-double (very open, overall). Basement stays fairly warm as is w/ running the dehumidifier. Pellet stove (Harman P38) in family room downstairs. We run a ceiling fan to circulate it through the downstairs. Has worked well so far (outside temps lowest so far in the 30's this fall). We are in Southeast PA. Plan to circulate it upstairs w/ our forced air "circulate" setting. Hoping to not have to turn the oil furnace on at all. Do you think this is doable in your experience??? We have 1/4 tank of oil, and we are debating whether to buy oil or how much we would need if we have to supplement at all. We have an 18 month old who is home during the day, so we keep the house warmer (75-78 degrees ideally).
