This house was built in 1800,we just had the test done where they checked the temp of the house and scanned for the cold spots. Well i have taken some chair rail off and found no insulation in the walls. The house has been vinyl sided and supposedly insulated underneath. Gonna take siding and clapboard off and insulate when we can afford it.The down stairs is all we wanna heat whereas the upstairs draws from the downstairs but we don't wanna sleep in an 80 degree room which is upstairs. It has between 700 and 800 sq ft downstairs and around 400 sq ft upstairs which can be closed off, or partially and small rooms though we know how to move the air.We have a Vigilant wood stove and i'm thinking too big. Not being insulated i realize this is hard to answer but i'm thinking something that heats from 800 to 1400 sq ft. I live in Maine.Any ideas guys? I have looked at everything under the sun and i prefer a cast iron with that Resolute,Leyden,Shelburne look.Also you can decide which on the cat or no cat.Thanks all.
