i know i have been on here before asking few questions here and there. don has told me that on the hudson river kinderhook i can up the btus with the stock board(maybe) or buy another. has any one else done this? not that i don't trust him. i am mainly looking for something with a big hopper so i can put it in my basement. but the enviro maxx, vistaflame vf170 and the kinderhook all have a 130lb hopper and from what i understand they all come from the same place. sherwood industries? the kniderhook is far less then the other two. i am from the portland area in maine so any dealers that would like to chime in also and give me advice and or prices you could pm me. i am ready to buy just havn't found the right stove to get. my house all together basement and first floor is about 2300 sq feet. it is a ranch. the basement is going to be insulated before winter.
