Fireplace Damper - Top or Bottom ?
After recently moving into our new house, we find our (wood burning) fireplace chimney has no damper. So we had a few chimney people to give us quotes and there seem to be contradicting views on whether to install the newer type top damper, or the traditional bottom damper.
Here's the benefits that I can make out:
Has a silicon/rubber seal so will be very efficient.
Cheaper, but likely to deteriate quicker.
Quoted $525 including installation
Made from cast iron so won't form a perfect seal.
Will last a lifetime.
Quoted $800 inclduing installation.
We do already have a good quality glass front door which I'm hoping does reduce air escape well.
What would you all suggest, and are these prices reasonable?
