Hello - looks like there is a ton of great info from some very helpful people on this site.... I am planning on installing a pellet stove (Regency Greenfire GF55) in the finished basement of my split entry (2000 SF) to try to offset my heating oil costs. Hoping for a 50% reduction in heating oil costs by using the pellet stove. A friend of mine has been able to heat his entire house (similar size) in a similar manner with the pellet stove in the basement and having the heat rise up the stairs and through a small (4" x 10") vent in the ceiling directly above the stove. Both the salesman in the store and my friend both are convinced that the stove will reduce my oil costs by at least half and maybe by 75%. I guess I am a little skeptical and hesitant to spend over $2,000 unless I get a 3rd, 4th, 5th opinion. Would appreciate any input some of you experts might have in a similar installation. Thanks!!
