>about 70 degrees and used for both floor heating and hot water
Underfloor heating? Is that not too hot to walk on???
Or is some kind of in-house heat exchanger used?

We have that at home, this is great. No noise, no maintenance, no emissions. The only downside is that you are "locked in" with a single heat provider.
I suppose new installation don't have the issue, but for stuff I'll use for a long time (basically house, computer and car), if I don't know how to repare it, I prefer old tech.
> About 9 % of the total heat demand in Germany is covered by heat grids today and 14 % of the demand for residential buildings.
What i dont understand is how it is efficient to deliver a constant 70 degrees heating pipe. There has to be some kind of boiler/trigger right?
The pipes are well insulated and apparently the energy loss quite manageable.
Depending on the specifics, that's often about 5x more efficient.
Counterintuitively - the "heat" source doesn't have to actually be hot. In theory as long as it's above absolute zero it can be used as a heat source to heat up the inside of your home. It's the same for cooling - even if it's hot indoors and really hot outdoors, you can still use a heat pump to make it even colder inside the hosue.
