Different Heating Concepts Compared

To look at it from a different perspective: A water circuit that distributes heat in the house is more flexible. You can connect solar collectors, storage tanks, water-bearing fireplaces, combined heat and power plants, electric heaters, local/district heating, or burners - or the soon-to-come fusion reactors ;-).

Just that alone is the reason for me not to go for an "air heating" system.

So my cousin has an air heating system, and so do two neighbors. They each also have a BWWP additionally; absolutely nothing about that is space-saving. These Proxon monsters probably take up about 2 sqm, and due to the piping going upwards, the space above is also not usable. A more space-saving option here would probably be a combined system controlled residential ventilation + air-water heat pump, like the Tecalor 504. Provided you have no reservations about installing a heating unit for around 40k. And yes, of course, you can mess up a lot in the hydraulics or simply design it as a standard 08/15 for 35-degree flow temperature. But even a botched underfloor heating system will hardly be as inefficient as an air-air heat pump. So, it basically boils down to acquisition costs vs running costs.

you're talking about a completely different system ;-)

He or she is talking about an air-to-air heat pump just like you (in your table). ;-) I had already suggested differentiating further there, but you just dismissed it. So is the distinction actually useful after all?

The thread starter is talking about a multisplit. There was never any mention of such a Proxon air-to-air heat pump!

the thread starter is writing about a multisplit.

this is about a VRF system and not a pure air conditioning split solution

So what now? And the OP also writes about gas + solar thermal for hot water, while you simply switched to (electric?) instantaneous water heaters. So let's summarize: the range of possible heating systems is larger than what the OP presented and also larger than what Alessandra presented as a solution. And especially with general terms like "air-to-air heat pump" you cause a lot of confusion. Which manufacturer installs VRF with cassette units in single-family houses? And what does that cost? And what COP is achieved?

Such trivialities as e.g. reality do not matter when you want to promote your own solution as the best solution in the world.
