I presently have a woodburning fireplace. We can't get gas but I do have propane and would like to convert our fireplace to this fuel. I don't use the fireplace for heat but would like to have an efficiant system in place. Any suggestions in regard to gas(propane) logs or inserts? I know inserts are more efficient, but is it worth the difference in price? I'm nervouse about ventless fireplaces even if it super efficient.
Thanks for your help, John

I think you should be concerned more about how to vent it, then the price. Do some research. I believe the rule for a ventless appliance is less the 40,000 btu's. Anything over that amount requires venting. You will need a conversion kit to go from natural to propane. It's relatively a simple matter of changing the orifice in the gas valve and adjusting the pressure regulator. Included with the installation is a damper lock to lock "closed" the flue. I'm sure some heat will go up the chimney in any case. Here's a link that you can read about vent-free appliances.

Had a situation similar to yours. We bought an 1100 square foot, 40 year old ranch home with a fireplace in the living room. In the interest of avoiding the hassle of a woodpile, we decided to install an LP 'ventless' insert in the fireplace for added heat, ambiance and a lower cost. While the living room is always toasty warm, this sucker throws off A LOT of moisture. The house has the original wood doors on it (probably highly inefficient in terms of insulating properties). The 9-lite back door (which is the only on we use) constantly collects condensation which runs to the wooden threshold and eventually caused the rails and stile to swell making it impossible to close the door properly. In addition, the system is not completely ventless, but vents directly into the room. While we have had to problems with a propane odor, I can't help but wonder how much exhaust actually enters the room. If I had to do it all over again, I'd install a unit that vented up the chimney since it's already in place. Best of luck.

The condensation problem can be taken care of by using a dehumidifier.

Convert the fireplace to a whole house heater with a corn stove fireplace insert. Whole kernel shelled corn is safe, clean, healthy, environmentally friendly, zero smoke, improves the atmosphere.
