Geothermal energy or gas condensing boiler?

Hi andimann,

"These power plants then mostly run at partial load, where the efficiency is finally dreadful. Ergo, the companies naturally try to operate the cheapest power plants they have. After the now shut down nuclear reactors, these are the lignite power plants."

Do I understand you correctly - you believe that nuclear reactors generated cheap electricity? Maybe this applies to the costs officially paid for them, but the storage will cost money for generations, which never let a single electron flow for it, let alone a kWh of this electricity be used. I don't even want to open the topic of the risks associated with the reactors.

You are certainly right that our electricity dependency has further increased due to heat pumps and that electricity, in particular, has a poor efficiency in the CO2 balance. I fully agree with you on that. When I look at the exhaust issue with cars, another problem becomes apparent; for many people it’s such a complex issue that they have to believe the statements of the manufacturers and inspectors (e.g. TÜV), and if the incentives are not high enough, then cheating happens. Did anyone really believe that an SUV burns less fuel than a Golf?!? Unfortunately, people only commit with all means and a lot of passion when it really comes down to the wire.

For this reason, it certainly makes sense to temporarily rely on gas. However, one should not forget to continue driving research and development in the field of renewable energies with great commitment.

Sorry, I actually didn’t want to respond to this, but I am firmly convinced that sooner or later we will have to manage a transition, and that will only succeed if the population also realizes that this will cause costs.

Best regards,

I unfortunately can't upload an Excel spreadsheet, it only accepts images and PDFs... So now?

Make a PDF out of it or send me a PM, then I'll do it for you. Rhineland greetings from the road Building expert

Hi,

Do I understand you correctly – you think that nuclear reactors produced cheap electricity? Maybe in terms of the costs officially paid for it, but storage will cost money for generations to come, who never let a single electron flow for it, let alone used a kWh of this electricity. I don’t even want to bring up the risk with the reactors as a topic.

No, I never said that nuclear power plants produced cheap electricity. Only for the operators were they super cheap because they were extremely subsidized overall. And the operators haven’t had to seriously worry about the final storage so far, and probably won’t in the future either. That is elegantly passed on to the taxpayer.

Until a few years ago, I would even have said that as an engineer I was convinced that nuclear power can be operated safely if you really want to. Since Fukushima, I unfortunately have to agree that this is not the case, or rather people are just too stupid for it. There will always be some genius who (to improve the balance sheet) cancels some maintenance, doesn’t comply with safety regulations, or as in Fukushima tried to save money already during construction and then didn’t properly protect the emergency power generators. If those things had stood 100 m higher on the hills, nothing bad would have happened in Fukushima at all. But such idiotic decisions will always happen, and for that reason alone the phase-out of nuclear power is the only right way.

Once again, hello,

to return to the question of the TE, here is an example calculation (unfortunately only as a PDF) that compares various heating systems. Depending on the current offers for different heating systems, the result may vary, but I think it is clear that heat pumps still have a very hard time, from a calculative point of view, keeping up with gas boilers.

Best regards,

Andreas

I am missing the connection costs for gas in the values, which range between 1500-2500 euros+, depending on location/provider. Otherwise, 6000€ for gas seems too low to me, after deducting only 4000€ remain, which makes it tight for the gas condensing boiler chimney and acceptance? Otherwise, I believe the maintenance costs for the heat pumps are lower, as there is no chimney sweep or anything... I wouldn't know where those should come from now, or why they are more expensive than the chimney sweep/emission measurements for the gas boiler?

Great work. However, the maintenance costs for the heat pump are too high for me (approx. 50 €). What should also not be forgotten is the innovation grant...
