CO2 Carbon Footprint Gas Heating vs. Heat Pump in New Buildings

sry, it’s too aggressive for me, I won’t respond to that anymore; happy to talk again in an appropriate tone.

Otherwise, thanks for the contributions, for me I note ...

* Photovoltaics still need to be considered individually
* possibly tank instead of connection
* It seems surprisingly controversial what gas heating and heat pumps cost to purchase (my sources are from 2024, unfortunately I’m not allowed to post a link). I would be happy if my numbers were wrong though.
* CO2 compensation is compared by some to indulgence trading, then of course the comparison makes no sense; however, I consider that a bold thesis, but luckily I don’t have to defend the concept here

... and I’ll leave it at that and wish Buchsbaum lots of fun with the thread.

It seems surprisingly controversial what gas heating and heat pumps cost to purchase

Well, here an actual, paid invoice from a real installation was posted...

* Photovoltaics would still need to be considered individually

No need. You didn’t include it in your calculation and neither did I. It should be undisputed that it significantly increases the advantage of the air-water heat pump over gas.

* possibly tank instead of connection

Spending an additional €10,000 on a tank can’t be an advantage. That was always a makeshift solution where there were no heat pumps yet for regions without a gas network.

* It seems surprisingly controversial what the purchase costs of gas heating and heat pumps are (my sources are from 2024, unfortunately I am not allowed to post a link). However, I would be happy if my numbers were wrong.

Well, I have made a very concrete calculation. Where do the data in your video differ? You can also give a tip on how to find the video.

And we have already received concrete calculations here as well. So real costs. These were clearly below your numbers.

* CO2 compensation is compared by some to indulgence trade; then the comparison obviously makes no sense; however, I consider that a bold thesis, but luckily I don’t have to defend the concept here

Here too, I specifically named the costs for genuine CO2 removal.

The company you mentioned primarily carries out development projects in poor regions, which may be useful, but whether it really helps the environment, I consider very questionable.

... and let it be

I find it very unfortunate that you no longer respond to my calculations at all. So basically you cling to your old position and break off the conversation.

PS: I don't have a chimney!

That is bad. I have something like that in the kitchen. Never without it again! But if you don't have a flue it gets difficult. Especially at Christmas time, such a kitchen stove is firstly a saving miracle because of the oven and secondly very cozy. But for that, you all have a nice heat air pump.
