Great Bernd!

You have no idea about a matter and you ask a question here. But you consider yourself competent enough to know that answering follow-up questions is not helpful...
Do you also treat the heating engineer like that? ==> give me an answer to my problem but just satisfy me with no follow-up questions!

I heat my hot water without a heat pump using a simple electric 80-liter water heater. If I leave it on continuously, it also has these load spikes like yours. At night just like during the day. So the heating element doesn’t heat constantly for an hour, but only briefly at a time. Normal, because the water in the tank naturally cools down. However, I have controlled my boiler with a timer switch so that it only heats from 10 a.m. to 3 p.m. That is the time with the highest photovoltaic power. That works great and from March to the end of October I have no electricity costs for hot water production. Now in winter, yes, but I can live with that. Now it also depends on how big your hot water storage is. It makes a big difference whether I have 80 or 300 liters of hot water available. But we don’t shower or bathe every day, rather only 2 to 3 times a week.

That doesn’t help the OP, since he has a heat pump. So it doesn’t matter what your electric boiler does. Besides, a heat pump—and not the heating element—should produce the hot water. Then the heat pump goes up to maybe 1.5-1.8 kW. A typical heating element in the heat pump is only 3 or 3.5 kW anyway—so it doesn’t fit the peak either. Unless Bernd would answer some questions...

You are clearly speculating too much.

In a domestic hot water heat pump, the heating element contributes to heating the hot water just like in a conventional hot water boiler.
And since you do not know the power at which the heating element in the domestic hot water heat pump operates, any statement about it on your part is pure speculation.

Thank you for all the expert opinions! Many of them are simply wrong, but discussing that does not answer my question. Since I obviously will not receive an answer, I will leave the dispute to the "experts". Thanks again for the attempt to help me! Best regards Bernd

Dear Bernd, thank you very much for your contribution, unsurpassed in ignorance and arrogance. Marienschatten is now on my "ignore" list.
