we now have 1 stove in the basement (pellet) wich heats the majority of the home better than I expected.upstairs in the living room I have a old heatilator style firplace original to the home wich was built back in the 40's.I have always used this on the weekends and sometimes during the evenings during the weekday to throw a little warmth into the room.it works fairly well and has come in handy during power outages, but it uses alot of wood compared to a insert or wood stove.I am looking into a insert for it and have a few scenarios. I can do a wood insert but to line the chimney with 6" stainless flue they will have to cut some of the heatilator out with a torch and do some masonry work so the pipe fits.I was also told that a inserts rated heat output is with the blower on, and in a power outage the heat output basicly gets cut in half with no blower. A pellet insert would fit great with no cutting and I could do it myself, and it would be alot cheaper, but im still faced with the no power no heat issue, unless I purchase a small generator.I dont think a pellet stove would draw alot of amps so maybe a smaller inexpensive generator would do the trick. Ive also looked at gas, but was told they basicly work the same as a wood insert and there output with out the blower is cut in half. Im leaning toward the pellet insert but would like some feedback from insert users, do you run a generator etc.
