Submeter for heating electricity?

Hello,

we have finished building (near Velten in Brandenburg), now the construction power finally needs to be removed. My electrician called me and asked whether we want one or two meters, and if we want an extra meter for heating. He himself advises me to have one electricity meter and run both house and heating electricity through it, because the savings on heating electricity costs are not that high and there is also the issue of "peak time / off-peak time," meaning that sometimes we simply cannot heat or have hot water.
I still wanted to do some research first, but mostly only found threads from 2012, so pretty old. We have a 6 kWh heat pump. Of course, I cannot yet estimate the annual consumption since we just moved in. I roughly calculate about 3000 kWh.

Here are some questions for which I have not found any answers:
1. The posts in the threads said that heating electricity is no longer that cheap and many therefore run everything through the house electricity. I briefly checked on Verivox: heating electricity costs around 19 cents, house electricity around 29 cents. So a 10 cent difference and possibly savings because of that. Did I misunderstand something or has the price difference for heating electricity improved again?

2. If peak time and off-peak time cost the same in consumption price, does that mean that there is no longer peak and off-peak time? We actually don’t want to give up the luxury of being able to heat / shower with hot water at any time... Or does this time division no longer exist? Or what should I pay attention to so that I don’t have it?

3. Is one still tied to the regional provider or can I change the heating electricity supplier at any time (of course in accordance with the contractual termination rights) (I know that works for house electricity)? In other words, could I even “save” twice with instant bonuses, etc.?

4. You can have two different electricity suppliers, one each for house electricity and heating electricity, right? So you don’t have to get both from one supplier if you switch?

5. This is of course a general question and probably no blanket answer: Does a second meter for heating electricity “make sense again” now?

Thanks in advance for all helpful answers.

I faced similar questions. I then decided on 2 meters so that I can easily read the consumption of the geothermal heat pump. If everything runs through one meter, that is not so easily possible. That was important to me because in the first years I want to find the perfect setting for the heat pump (flow temperature, heating curve, etc.). What really turns out to be cheaper cannot be said yet since you don't know how much the heating consumes (vicious circle). Regarding 3. You can switch again and again and collect a bonus for both household electricity and heat pump electricity. Regarding 4. Yes, you can have 2 different providers. Peak and off-peak times apparently no longer exist. At least not with the providers I have looked at. Likewise, there are no longer any blackout times. That means you can heat at any time. If at all, only 1-2 hours per day were blocked anyway. You wouldn't have noticed that anyway because your water and underfloor heating have certain water buffers that do not cool down in such a short time.

So we also took 2 meters, solely to keep track. Apart from that, we consume about 4000 kWh and save approximately 8 cents per kWh, which amounts to 320.-€. The meter costs €9.80 per month, so it's already worth it.

So you can also have an intermediate meter installed if you only want to read separately, which is cheaper in the long run than paying fees for a second meter (if that is the only reason). Otherwise, it varies a lot regionally; if there are tariffs where heating electricity is much cheaper, you should definitely get two meters. I got two, but currently only save maybe 50-100 euros a year, so it can possibly become unprofitable. Usually, with an air-to-water heat pump, you will need around 3000 kWh.

Quickly found one from last year that I could remember:
But there are several threads about this.
For us, two meters would never have paid off. I had a sub-meter installed afterwards for that.

With us, the second meter (which we actually had) was no longer worth it already in the first year. We need about 2,000kWh heating electricity plus 1,000kWh hot water. At 4ct savings, this amounted to 90 euros per year. But the additional meter also had to be paid for. So in the end, no difference anymore.

Since we installed a photovoltaic system, the second meter was even less worthwhile. So it was taken out.

The only question you should ask yourself is therefore: Is the price saving > than the additional meter fee.

WARNING: There are household electricity providers who exclude the operation of heat pumps in their terms and conditions.
