How complicated are heat pumps in practical operation?

eh. For the traffic network, it also makes more sense if everyone drives to work at once and for 3 hours ...

So - this is my last attempt and maybe it helps to stay in your image: If the commute is the same and the same number of workers have to travel the route every hour, it is better if the cars at every entrance ramp enter the highway evenly coming from a roundabout, rather than putting a traffic light at every entrance ramp that briefly releases far too many cars onto a single ramp. This leads to traffic jams and fewer cars arriving on time. Which causes those who are late to accelerate extra hard. Which leads to even more traffic jams = The network is overloaded, energy consumption is higher. Oh, and: No utility company is interested in ERRs for underfloor heating. What you are referring to is the remote shutdown of heat pumps during peak times. No connection.

What a comparison!!! Where and what are the traffic lights supposed to be in the power grid? What about the roundabouts? What do you think is the reason for the ERR regulation? Simply because the BMU once had a great time on a Saturday and wants to fool people? But yes, I know. A deliverer must deliver. Thank you for explaining the world to me and now I know that 5 years of studying were completely for nothing!

It probably didn’t help to stay in the picture... And sorry - I didn’t know that you studied. In that case, you must have noticed that everyone here contradicts you, which will surely lead you to read up a bit more on the topic. And regarding the meaningfulness of the guidelines of the outgoing federal government as well as their attitude towards the economy and science, I hopefully don’t have to say anything further.

I see no contradiction. Always just comparing apples and oranges. But yes, I will read up on it again…

In this case, you must have noticed that everyone here is contradicting you,

To stick with the highway example: This morning on the commute, hundreds of wrong-way drivers came towards me, who even rudely honked at me and performed wild evasive maneuvers. Crazy!

Disclaimer: everything that follows actually has nothing to do with the topic.

This causes the heat pump not to run continuously and to have more frequent standby times.
This, in turn, relieves the power grid.

The latter is incorrect.

Let's do a thought experiment:
We have 10 heat pumps that each deliver 24 kWh of thermal energy to the house per day.

Variant 1: steady 1kW -> maximum "grid load" 10kW
Variant 2: cycling with 1 hour off, 1 hour on with then 2kW -> maximum "grid load" 20kW
Variant 3: cycling with 3 hours off, 1 hour on with 4kW -> maximum "grid load" 40kW

Here we can see that due to cycling or downtime, the peak load increases and thus "the grid" is more heavily burdened than with systems that modulate down and run continuously.
Of course, there are various intermediate variants and also more extreme ones, but none has a lower maximum load than variant 1.
