1900 Sq Ft is relative to what part of the country you live in. 1900 SqFt in NYC would run you 7g's+ a month in rent and would be a good size aparment. My brother lived in NYC and was paying $2500+ a month for about 400 SqFt. I have seen walk in closets bigger than his apt was. The average "CapeCod" style house in the New England area is between 900 and 1200 SqFt. Our "Chalet A Frame" comes in at about 950 SqFt and was heated for years with a tiny Morso Squirrel and it kept us nice and warm. (Mid 70's 2 adults and a dog) The house I grew up in the middle part of the country was close to 4000 SqFt and was typical for the area. Average house size varries widely from one part of the country to the next. Heck even from City to City, Town to Town things can change.
My experiance (just me) is Euro stoves pack more bang for the size than American made stoves. They also have better exterior designs as well from my point of view. And I use our little Morso as a prime example. New England can get pretty cold and no matter how cold it was that little stove kept us warm and while our house is less than 30 years old which is new by N.E. standards I would say it has fair to just above average insulation and we are always going in and out with the dog. (Except on Sunday afternoons during football season!)
My point being those small Euro stoves pack a great punch and I wish more of them would be sent this way. One of the problems I see is overcoming the idea that many have is that to heat a large area you must have a big stove and that isn't always the case.
Any.. That is my ramble for the day!
