In this thread it is explained several times that hybrid or multiple solutions usually do not really make sense (also economically), otherwise they would probably have long been established on the market as a jack of all trades. Here, too, it is complex and from my point of view I would first of all advise you to reduce the insulation quality below Kfw40. I had a house with 36er Poroton and now one below Kfw40. I could not have imagined it that way, but in fact the rooms cool down significantly less, which means you have to supply less heat. Regardless of the heating system, that would be my first step. From that and the fact that we absolutely wanted a fireplace and use it often, the decision was made for a supporting infrared heating system, although this is still designed as the main heating system but is used rather less frequently. Then we have a Daikin multi-split in 3 areas and for us the system only fits in this combination and to our lifestyle. I read occasionally that people constantly need 23-24 degrees, among other things, which is different for us. Often I also read that air-to-air heat pumps or air conditioners feel like a hairdryer, which is of course meant disparagingly. Ultimately, you really have to look at it closely yourself, preferably live-test it, also because everyone is naturally convinced of their own system and often no other opinions come into play. Everything is possible and there are advantages and disadvantages for everything. The heat input through windows also plays a role; for example, from the end of February to November we often need no additional heating at all. My opinion is therefore the high insulation standard and definitely a standalone controlled ventilation system AND an air conditioner. Whether you then still need an expensive air-to-water heat pump with/without underfloor heating depends entirely on you; for us that was answered by the fireplace and we are very satisfied with our energy consumption. I would also always install a controlled ventilation system again, because the air quality is really noticeable to me and also gives me the good feeling of sitting on the sofa virtually outdoors. That’s how it is for me! Our air conditioner cost 10k but is equipped with generous units, costs virtually no electricity due to photovoltaics, and in winter we use it occasionally for supplementary heating, e.g. in the morning when the sun does not yet bring enough warmth into the room or briefly in the evening. I do not find that unpleasant and even if a warm breeze were noticeable I would find that pleasant. You can also look at where to place the units, plus there is a swivel mode etc. Electricity consumption is low, also because it only runs in power mode for a while and then continues at a low level. These are my experiences and the opinion that actual cooling is only achievable with an air conditioner. By the way, our hot water comes from an AroStor heat pump.
