Well, a question of space: if you have a large utility room, then Monoblock. If you have space outside and no neighbors to bother, then Split.

I thought it was exactly the other way around? Monoblock = everything outside, with Split you still need an indoor unit.Well, it's a question of space: if you have a large utility room, then Monoblock. If you have outside space and no neighbors to bother, then Split.

Yes, that is also the case.
Monoblock = everything outside -> water pipe through the wall.
Split unit = half inside/half outside -> refrigerant line through the wall

At least 2 water circuits are connected to a mixing buffer. One circuit is the heating circuit of the heat pump, the second circuit is the underfloor heating. The mixing buffer is charged by the heat pump. The underfloor heating circuit draws heat from the mixing buffer. In order for the heat from the heat pump not to dissipate in the mixing buffer, the buffer must be discharged to the same extent as it is charged. The two water circuits must therefore be optimally coordinated in terms of flow. Actually no problem. However, as a rule, the heating circuit pump of a modulating heat pump is power-controlled, while the circulation pump of the underfloor heating is not. This renders the concept of the modulating heat pump absurd.

The mixing buffer is charged by the heat pump. The underfloor heating circuit extracts the heat from the mixing buffer. In order to prevent the heat from the heat pump in the mixing buffer from dissipating, the buffer must be discharged to the same extent as it is charged. The two water circuits must therefore be optimally matched in terms of flow. Actually no problem. However, as a rule, the heating circuit pump of a modulating heat pump is power-controlled, whereas the circulating pump of the underfloor heating is not. This leads the concept of the modulating heat pump ad absurdum.
And what does that mean? Mixing buffer is useless?

Brings only problems, at best it just significantly reduces efficiency. With modulating heat pumps, a mixing buffer is a no-go.
