hi can you all help us? for us a wood burning fp insert is a BIG investment so we want to make sure we get the right one. because of dealers in our area we are deciding between the jotul 350 and the hampton 1200, they are about the same price. i keep trying to find out what the cubic footage is of the jotul 350 winterport firebox, but no one seems to know! the hamptons is 1.4 cu ft which seems small? i want to know which one has a bigger firebox, and do you think we should maybe spend more and get a bigger unit like the jotul 450 or the hampton 1300??? we want to heat the main floor only which is 1000sqft. and we live on the west coast so it rarely gets below 0. any comments would be appreciated!
