Well I could'nt resist. Since the circulator in the basement seems to have a problem I stole the can from that. It worked great. Baby-sat all night(slept on the couch) Got pretty good heat 7 degrees F outside inside 62. normally furnace is set at 58 at night, comes on 3 or 4 times with that ouside temp. Didn't come on once.
As posted by others in the past tread, be careful, mine seems to work great.
