My grandmother has offered me her 1994 Regency F3000L for only $200 and it's in great shape. From what I figure it is just like the F3100 Classic that Regency still sells. Its the same size etc. If that's true that means it is a 80,000 btu stove. It also has secondary combustion tubes (must have been state of the art for 1994 right?). That's the good news. The bad news is our home is only 1,250 sq ft. I think that I would be ok loosing some space in my living room to install it as compared to a smaller stove (it's worth it, lots of great memories around this stove as a kid), but wouldn't it heat us right out of our little home?
