I understand my post was not confusing. I was questioning why you need to pay twice for a service…

That the delivery was scheduled at that time is a whole other level. Crazy stuff!

Maybe give me the benefit of doubt and don’t interpret things? I meant that the service was already paid for by the sender and now somebody has to pay again? Seems strange to me at least…

I mean the sender already did, right?

Yeah in what world do you need to pay to get your parcel delivered ???

It happens so faaaast

Our family home in Germany is completely covered in it…

Love it, thanks!

Great work! Do you have some more pics or maybe even a video?

Sure it can. Battery state, temperature and all is controlled by software…

If you are comparing gas to heat pump efficiency, it is more like 85-90% vs 350-500% efficiency.

Because in the gas furnace efficiency they only calculate the efficiency of burning gas but miss to include the auxiliary electricity that is needed to run the system.

In a heat pump system everything (running fans etc.) is included in the efficiency calculation. The efficiency itself is depending on the source of the heat pump. In a really harsh climate a ground / geo thermal source might make sense. But usually the average temperature is higher than you might think.

And for the environmental effect: modern gas power plants run at 50-60% efficiency so with a heat pump you are always burning less gas even if the gas plant is less efficient then the gas furnace.

It would be interesting to know what extreme cold means.
