The loss will be fairly negligible compared to the cost of preventing it as plastic pipes don't conduct heat well and neither does still air; but if you want to invest in removing even that tiny little bit you could box in the pipes on the outside with insulated ducting. The expense probably wouldn't be worth it though.

Aren't waste pipes mostly empty apart from the water in the S bend? There'll be no direct air movement from outside to in because of the S bend, and the water movement will always be in the one direction (taking warm out, but not bringing cold in), so it doesn't seem to me like there's an issue here.

Given that you seem to be not using it that much, you'd be better served not using it at all. Ventless fireplaces are extraordinarily dangerous and banned (for good reason) all over the world.

Within an hour of turning on a ventless fireplace, whole-home levels of toxic and dangerous combustion products exceed WHO safety levels. They literally fill your home with poison.

Oh sorry, you're right - it is very expensive. I made an assumption based on some of the background in your photos that you could. The Kreg looks like a good in-between. I know whenever I tried to use the circular saw and just a straight edge my cut would always wander. The Kreg looks like it will at least keep the saw close to the track.

It looks like the valve will fit, but good thoughts. Yeah, we only turned it on once last year on low for a few hours. The only time I'd really NEED it for heat is if the power goes out in the winter. We're in SE North Carolina so that isn't likely. If it did, I usually have a back up tank or two filled anyway for the grill or another fire table that's on the back deck.

Ah, good thoughts! I'm in Coastal North Carolina. Rarely gets below freezing, but we've had a lot of nights in the 30s this winter. It's on the north side and will be regularly shaded.

The tank is just outside the fireplace. Maybe 4 feet of thin metal piping for it. Would insulating the pipe be worth it?

The answer is maybe. Depending on how cold it gets where you are and how long of a run it is to the heater the small tank may not provide enough pressure. A 40lb tank might be a good compromise, still a larger size but small enough to be moderately easy to transport for filling.

Yeah should work fine, I do it now and have been for a while. Not sure what valve they have on the big guy so might need an adaptor. Also you probably used a bit more than 2gal., If they filled it in a warm day the gas expands a lot. You can only get a good read on propane by weight so don't be surprised if you go through a few tanks, still less than 80 bucks. Also to get a tank. a lot of uhuals just leave the bad tanks out that people pay them to take. Ask for or take one and exchange it at HD or Lowes, save 40-60 bucks
