Hello everyone,
We are about to start the electrical installation work and are wondering what size distribution board we should have.
Our house is 180 sqm (1,937 sq ft), with 2 full floors, an air-to-water heat pump, underfloor heating, and a photovoltaic system with battery storage. Because of this, we probably don’t need a separate meter for the heat pump electricity.
Our electrician initially recommended a four-module distribution board, for the main house and a separate apartment (which we don’t have), the photovoltaic system, and the heat pump electricity (cost: €1,100).
Our solar installer said we only need two modules, for the house and the photovoltaic system (cost: €520). However, I’ve recently read that it’s better to plan for a larger distribution board.
I will definitely consult our electrician again but wanted to hear your thoughts on this.
Thank you very much!

not just the usual 2 electrical circuits per roomNowadays, it’s quite common to have one electrical circuit shared between two rooms. No separate lighting circuit.
However, I think the best approach is: if there is enough space, go for a larger setup. If you have network cabling, it’s a good idea to install a cabinet where you can also mount a patch panel, router, etc. ("full cabinet with multimedia panel")
One size up. Either a 4-slot panel or, as already mentioned, a 3-slot panel with a smart meter (check with your utility provider!). For a heat pump, a ripple control receiver may be required, and it also needs space somewhere. In the example, I don’t see any additional distribution box (APZ)!
My typical example: The electrician planned a 3-slot panel (2 for smart meters, 1 APZ), ripple control receiver (RSE) mounted on a DIN rail, and got approval from the utility provider.
When the utility provider tried to commission it: smart meter … Whaaat?
Later, the utility provider: What, a heat pump? RSE missing!!!!1!elf. Where is the 3-point connection from the last century?
End of the story: APZ removed, 1 slot replaced with a 3-point connection, and not enough space left for circuit breakers in the 3rd slot.
Therefore: If possible, go for a 4-slot panel 🙂
