Thank you for yours as well. It's an interesting discussion. As another commenter pointed out, it all depends on the electricity source regarding the carbon life cycle. I posted another comment with the best detailed analysis for my current environment I could come up with and it's clear to me that the result doesn't warrant a definitive positive outcome for the heat pump. With a low CO2 emission electricity source, I would agree that a heat pump system can make a lot of sense if your goal is to reduce emissions. > I think monetary costs are just taken for granted if you do not see burning fossil fuels as the only solution. That sounds like a rich people's perspective. What if you don't have the money? If it's really about transitioning the heating of all homes away from carbon emitting sources, then this will only work if the solution is cheap, because not everyone is wealthy enough to afford the transition. If you implement policies that force people to upgrade, as was done in Germany, you will only transfer even more wealth from poor people to rich people. And I would argue that this also reduces the overall wealth in the system substantially since energy is an input to any product or service. At some point that leads to serious social and political issues as can be seen in Germany right now. This puts the whole enterprise of transitioning at danger once people demand radical political change.
