For a standard single-family house with an air-source heat pump, how many slots for meters does the main electrical meter or its enclosure typically have? Our electricity provider requires a bidirectional meter for the heat pump and a disconnection device to be able to isolate the heat pump from the power supply.
Or, to put it differently, in which standard sizes are meter enclosures available—1, 2, 3, or 4 slots—or are they only offered in increments like 2, 4, 6, and so on?

I’m pretty sure you don’t need a fourth meter slot for the ripple control receiver. In the past, these were mounted directly on the meter, so even then, no additional space was required. Technically, it wouldn’t make sense. Today’s smart meters won’t make it more complicated.
You will have one with two meter slots (house + heat pump) plus one compartment for the wiring.
If you want to install a photovoltaic system on the roof later, there are so-called bidirectional meters available. However, they also have some drawbacks. It would be better to spend around 100€ more to get a larger meter cabinet and leave one slot free. But that’s up to you. I would recommend discussing this again with your electrician.
You can also add a smaller cabinet somewhere later specifically for the photovoltaic system, but that would be the least ideal solution.
To answer your last question briefly: Yes, it works.
