I don't know. How do I find that out?

Why do you need the heating element if you have a heat pump? The heating element is used in Siberian temperatures or when the actual heat pump has a problem. Otherwise, it can be deactivated.

We only had the heating element installed 3 weeks ago. It uses the excess energy from the photovoltaics to heat water…

Circulation: Does hot water come quickly at the tap/shower or do you have to wait a bit? Otherwise, check the offer or ask the heating technician!
Circulation means that the hot water is continuously pumped in a circle and naturally cools down, so it needs to be reheated accordingly.

Heating element:
Your heat pump has one integrated. So you wouldn’t have had to buy it separately.
And besides, it’s more efficient to generate hot water with the heat pump even in sunshine than with a heating element.
Did the same heating technician who messed up the rest talk you into that?
If you say the heating element is off, do you always mean only the newly installed one?
Urgently check whether it is only activated in the heat pump at severe subzero temperatures!

Hot water comes almost immediately, so yes, we have circulation, which I think is turned off only at night. The integrated heating element was switched off last winter so that it only switches on at severe subzero temperatures. The new heating element was sold to us by the electricians; the built-in one would not have worked together with the photovoltaic system. It only turns on when there is surplus energy that would otherwise be sold. And selling hardly brings anything; buying electricity is more expensive. That’s why this idea. So in summer it heats the water up to 75 degrees and we don’t need any electricity.

Again. Please read my post from page 1 and review the technical data of your buffer tank. That should be self-explanatory.

To be found there. The domestic hot water heating takes place through the [Durchlauferhitzer Prinzip]. You have almost no hot water storage in your buffer tank.

In plain language, this means that neither your heat pump nor your photovoltaic heating rod can significantly heat your hot water.

And water heated only to 40 or 45 degrees should be warned against.
It also makes no sense.
