$500 dollar 3 Day FirePlace Make-Over:
Day 1 - Friday - Planning
Enjoy red wine and cheese while you check Craigslist for a Chimea and for a used 26 to 36" or LCD TV. The red wine is necessary to help you make good impulse purchasing decisions.
Day 2 - Saturday - The Work Day
Early on Saturday morning get a small strong coffee (see attached) from StarBucks and go buy the Chimea and the used LCD TV before anyone else gets them.
On Saturday afternoon close your flue. Add a plywood insert with a gasket to improve sealing the chimney.
Hang a little sign from the plywood that say 'Remove This Before Burning Anything Here'
Then set up LCD TV inside in the fireplace with a hidden DVD player. Get a DVD with a variety of fireplace videos.
While you watch the videos go online on your phone and find a better electricity provider with a lower rate.
Use the savings each month to buy some caulk and re caulk your windows.
Before you start caulking stack the wood outside next to the Chimea.
Day 3 -Sunday - Relax and Reflect
Burn the wood in your new Chimea while you enjoy more red wine and cheese and check Craigslist for more impulse purchases.

It's regular masonry but with a gas line going into it. It's standard size and shape, but there's an overhang at the top which keeps heat from escaping from the fireplace. We've used wood a couple times and you can sit right in front of it and barely feel anything. Also, a friend volunteered to cover the fireplace with some spare marble tiles he had, so it looks great but I think if we do anything with the fireplace we're going to end up cutting into the marble.
I did find out that there are certain fireplace inserts which qualify for the 30% energy efficiency tax credit, but what I've seen so far is $1500 minimum cost just for a unit (not sure if it's even tax credit qualified), and around $2500 seems pretty common. A kit would be great! I need to keep looking.
Your question about water near the fireplace - a "heat sink" - is a good one. I was planning to ask questions on the issue someday. I think black stone is supposed to be a good heat sink. Also, the electric "radiator" space heaters use some kind of oil. I suppose water loses heat pretty fast.
Any input from the experts on heat sinks would be great! I'd like to know how to take advantage of our south-facing picture window in the winter. A list of useable materials would be great.

Is it a regular masonry FP or one of those gas log things? When I lived in Portland OR. they used fireplace inserts, kind of like a pot-bellied stove but built into a FP opening. Alot of people then used a cooling thermostat and an inline exhaust fan to suck out some of the hot (and I mean hot) air and pump it to the bedroom areas or wherever was needed via an AC duct in the ceiling. Another device was the same cooling therm and fan in a room with windows that faced south and dark tile floor/wall. The passive heat build up on sunnier days could be moved around the house as well. Take some pics so we can see the situation, there's always a way to pester something.

On a side note, the oak from Ike that I stacked last year came in pretty handy this winter. Got a little needed exersize as well splitting it. Burns hot and relatively clean as fire wood goes. I wonder if large tanks of water near a hot FP could hold the heat for awhile??? Hmmm. Anybody?
