How to supply a gas fireplace with gas?

Yes, I can follow the argumentation as well. But in my opinion, the "rustic romance" of gas is being neglected and burning wood is portrayed more negatively than it actually is. I'll put it this way: the argumentation resembles a promotional brochure. Having a gas line installed just because of a fireplace seems exaggerated to me; the main reason clearly leans towards a wood-burning fireplace.

Thanks for the invoice. I was a bit off then.
But I think it doesn’t make it any better if the fireplace is on for 5-6 hours straight. Although I can't yet estimate how often and how long it will really be on. But thinking about my wife... it will be on a lot.
According to the fireplace builder, the costs for wood and gas fireplaces are almost identical and therefore not a criterion for the choice. Regarding heating, the expert says that gas is cheaper than the wood option if you also have the wood delivered. Also, I have two left hands and would probably chop off my leg trying to split wood.


He spoke very much in favor of the gas fireplace. But he also repeatedly emphasized that he actually comes from wood stove construction and absolutely sells both. If we want, of course, we can also get a wood fireplace. But for our house with our "requirements" and conditions, he says he would definitely choose gas. We hadn’t considered that, now it’s really rattling around in our heads.

I also made an appointment with another stove builder. Curious to see what he says.
The one with gas was the second we visited. The first completely advised us against a fireplace with three-sided glass because it would get too warm and the three-sided ones get dirty incredibly fast. But that fireplace builder is out. We found him too unsympathetic.
Curious to see what the next one says. Although I have no idea if he even offers gas fireplaces.

One more remark: Having the gas line installed by the supplier also means a gas meter that must be visible - i.e. if the gas connection enters the house in the utility room, the line inside the house must already be under the screed/in the wall to the stove or you have a gas meter in the living room

You are right there. The connection would then lead from the street to the basement. I would need a gas meter there and would have to lay the pipe across the house to the other side to connect the chimney there. As I said, I don't like the effort involved. I have to see what we end up doing.

Therefore, it definitely burns for a few hours more often in winter. Let's say 6 hours a day.

So, at the moment we don't even have a house close to Kfw55 standard, and a closed wood stove from Contura. If I were to run it for 6 hours (that is, start it with kindling wood and 2 logs, and then add wood about 2 more times), I could switch to sauna mode in the house.

It has around 3-7kW according to the manufacturer. According to the instructions, I could load it with 3 logs when adding wood; but then I would have to open several windows...

Alright, the 6 hours were probably a bit too much after all. But that’s exactly the point. Sure, with gas it’s also real fire that produces heat. But you can turn it down and when you turn it off, it doesn’t keep glowing and radiating warmth for half the night.
