This microplastic story comes from a study from 2021 (?), which was conveniently interpreted by corona deniers. Just as a side note – yes, microplastic was found in the lungs. Even dozens of variants. With a sample size of exactly 13 people... By the way, I don’t care at all, because what I inhale without a mask or, for example, on a crowded train before corona is definitely not any better ;)

I just checked. My heat pump consumed 852 kWh for heating last year, producing 6636 kWh.
House KfW40+ with about 250m2 living area.
Now, as an engineer, I’m also an optimization nerd and have dimensioned my heating, insulation, masonry, etc. myself and additionally have a wood stove that was used fairly often.

It fits in new buildings, but hardly at all in old buildings.
As always

Intense! But it would be fair to say that it’s not an air-water heat pump. It must be geothermal, right? In new buildings of this size, most need between 2500 and 5000 kWh depending on the system and optimization!

Why do you all actually pay so little for electricity??? Even before my new contract in March with 0.45 cents, I was still paying 35 cents, which is significantly more than what you pay. Why is that? And if the cap is introduced, I will probably still pay 45 cents because of the contract term.

The thing with the demonstrations and the reporting is a known phenomenon. There have already been reports about it in public, but you usually have to investigate a bit.

Sorry, yes, it is a brine-water heat pump. LWT 28° etc...
And the truth is also that such expensive system technology would never be economically viable under normal circumstances.
So energy costs vs. acquisition costs.
It all originated back then from this insane KfW subsidy.

That is simply completely different regionally and not comparable. I think is with the same provider as me, hence the cheap price. Our provider produces a lot of electricity themselves and therefore hardly has to buy anything expensive.
