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?

Looks like this: https://en.m.wikipedia.org/wiki/Parthenocissus_tricuspidata

Our family home in Germany is completely covered in it…

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

[–] [email protected] 9 points 2 years ago

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.
