Our Technibel heat pump (about 10 years old) has finally reached the end of its life after roughly 10 years, so we needed to replace it. Technibel apparently no longer sells products in Germany, and initial quotes for a unit from another manufacturer were around EUR 12-15k (including installation, pipe adjustments, etc.).
Our heating technicians advised us to try to find a stock model of our Technibel pump, as the replacement would be much cheaper with fewer modifications required.
I have now actually managed to find a stock unit of our heat pump (with the same technical specifications). However, I did not pay attention to one detail: the pump was apparently intended for the French market and operates on 230V (not 400V like the version for the German market).
Now the electrician is telling me that I need a special approval from the grid operator to connect a 230V heat pump.
Is this correct? Do you have any experience with this?

My heat pump also runs on 230V; I didn’t need any building permit or planning permission for it.
I also don’t see why you would, since any hairdryer uses more electricity than the heat pump.
However, for the flow temperature, you’ll need a pump with a lot of power, because you can’t push unlimited current through a single phase. There are limits to that.

Technical specifications of my replacement 230V pump:
Heating capacity (A7/W35): 11.5 kW
COP (A7/W35): 3.66 (with circulation pump)
Cooling capacity (A35/W7): 8.6 kW
EER (A35/W7): 2.57 (with circulation pump)
Heating connections: 2x DN25 (1" male thread)
Operating voltage: 230/1/50 V/Ph/Hz
Maximum operating current (heating): 21.3 A
This pump was sold as standard in France. Therefore, I assume its performance is within the expected range.

Technically, this shouldn’t be a problem. Our pump is protected by a 30A fuse.
However, I would question whether it makes sense to install a pump that is 10 years old.
What is the cost of the device? There have been significant advancements in pumps over the last 10 years. Reconnecting two DN25 pipes can be done by yourself in about 2 hours.
