Sorry, LH - wrong on the FP question - Sandi had the right answer.

Secondly, I mentioned before I have a gas fireplace that I don't use. Can I just rip out the gas logs that are there and use regular wood logs?? NO. Gas and Wood use entirely different chimneys. Wood burns a LOT hotter, with sparks going up and creosote forming inside the chimney. Does the chimney need to be inspected? Gas inspectors need to inspect the gas connection. Wood chimneys should be checked - summer is a good time, as cleaners are not busy! :-)

If you really want a wood burner, you will need an insert and the insulated chimney installed.If so, any clue what that costs?? Do they still have those skinny guys in tops and tails who clean them??? Those sweeps guys??? (I know I'm thinking Mary Poppins... forgive me)

Your gas FP might be better than a woodburner....there should be a 'grate' under the main glass that lifts up from the bottom. Inside will be a metal tag (possibly under a LOT of dust ). Find the make and model number there. If the model # ends in N or B, it's a natural vent, and draws air FROM the room to the outside for combustion.

If it is a direct vent, then adding a fan would give you more and cleaner heat than the wood would LOL.

If you want to post or PM the make and model I'll do a search for you.

(I worked at a fireplace and HVAC store for several years, which is why I am such a pain.... )
