Hot water circulation pump

Most people probably consider the cold water before the warm water as a waste. However, it is overlooked that avoiding this causes much higher costs than the cold pre-flow ...

Depends on the production - and I consider water to be more precious.

But that is not meant to be the main argument - for me, it’s about the comfort aspect.

The water is not lost after all ...

Are you serious? cool...

I don't know, but have read it often enough now.

Thank you for the forbidden ( ) link - but it is also just one perspective and is based on the basic idea that it cannot help the regions suffering from water shortages.

OK, then we can continue to throw away our food in abundance - it doesn't help the hungry people either, if my quark is half-full and ends up in the trash can.

As I said, the basic idea of saving the most precious resource was rather secondary.
