After reading a previous post around gas log fireplaces and seeing the responses, I now have a question... We have a gas log fireplace insert in our house, we never use it because it seems to be a waste of gas. It doesn't seem to put off any heat. I've lit it before for 30 minutes or so and been able to place my hand on the surrounding marble tiles and they would simply be room temp or cooler. It appears to me that there is no heat retention and it's all going up and out the vent maybe. I'm no expert by any means on these so I'm wondering if there is a way to make this unit more efficient to use from time to time. We aren't looking to use it on a daily basis, but maybe really cold mornings and it would be nice to have it going on Christmas morning, but to serve a purpose and not just for looks. I've been told by a couple people that I might be able to swap out the logs to a different type, but it was simply a thought. I have no idea what direction to go with this in the event that is what I need to do.... Any help would be greatly appreciated.
