Hi, I am new to gas stoves although I do have a small wood stove for occasional use. I have a credit at a store where the only thing I'm interested in purchasing is a gas stove. The only model they carry that I would consider is the Serefina. Could somebody answer these questions? Is the casting of good quality? Does the flame give a realistic presentation? Would the enamel painted models look ok in a formal setting? Would 30,000btu over heat a 500sqf room? (lots of openings to other rooms) Whats the general quality of the lennox hearth products? Is the Lennox Hearth sale going to have an impact on parts, warranty, etc? Would I need a white stove pipe to match a white finish or is matte black ok? I know some answers to these questions will be opinion based. That's ok. Thanks in advance!
