Hi all....We are buying a new insert to heat 1500 sqf of main floor bungalow and all my research has lead me to the Osburn 2200 insert. Big bay window, mid size fire box good burn time excellent btu...Canadian made with a great price point ,,,2300 dollars cheaper than a quoted Merrimack. But i still have some conflicting information on the unit from a dealer that wants to sell me a hearthstone Clydesdale...Baffle non replaceable? wears out and unit no good after 4 to five years .... any input good or bad will be much appreciated thank you
