Normally we have 20f at night or colder. But last couple weeks it's been 28-32f. So I just save a little wear and tear and keep the fire going by switching to Manual vs Auto. Last couple days ran it in AUTO. Yesterday burned 20% of a bag of pellets keeping house 74f (Hallway). Today looks the same or less (It's 32f and 2" of new Wet Snow). In the day when it warms up to 36f I switch it off. Strange winter so far. Last year we burned 3 tons. Looks like at most 2 tons this year with 35 bags on porch still. In March will switch to Furnace if the temps hold above 30f and no snow. On Manual we were burning 1/2-3/4 bag. Quite a savings. Still need to get spare part on hand for when it fails in 10 years I hope.
