ᐅ The heating options – air-to-air heat pump, air-to-water heat pump, or gas?

Hello everyone,
I have long understood that heating is a complex topic. However, the fact that different suppliers give such varied recommendations only adds to our confusion.
We quickly decided on the following heating system – an air-to-water heat pump with controlled ventilation, supported by a photovoltaic system. Our reasons for this choice are:
Strangely, this supplier also offers air-to-water heat pumps.
What do you think about this statement?
Based on my research so far, I understood the situation quite the opposite and have found more negative feedback concerning air-to-air heat pumps.
We were also informed about the “noise” produced by an air-to-water heat pump. We would prefer not to have a split system but a single unit placed in the basement. At the moment, I can’t imagine there would be a noise issue.
Does anyone have experience heating with an air-to-water heat pump?
Additionally, we have the option of a gas condensing boiler (including underfloor heating). Initially, we dismissed this idea, but the lower initial investment costs are making it more appealing now.
Is there anyone who has built with this and can share some insights?
Ultimately, it probably depends on how well the house is insulated, but some kind of heating system has to be installed, and we want to choose the “right” one...
Thank you very much in advance.

We quickly decided on the following heating system – an air-to-water heat pump with controlled ventilation, supported by a photovoltaic system. Our reasons for this choice are:
- No dependence on fossil fuels
- Low running costs due to the photovoltaic system
- Future-proof, since with underfloor heating installed, it would be easier to switch to newer technologies in 25-30 years
- Comfortable living space thanks to even heat distribution through the floor

Yes and no. Here, there is definitely the option to shift investment costs onto operating costs – if I were a builder or contractor, I would be foolish not to do that.
Whether it is $50 or $80 per month may not sound like much at first, but over 20 years (the estimated lifespan of the heating system), that adds up to $8,775 (or $7,200 without 1% annual inflation).
Of course, no one will go bankrupt because of it – that’s clear – but I find it too much to completely ignore.

but for 20 years (that’s how long the calculated heating system lasts) No gas condensing boiler lasts that long; the condensate produced contradicts this lifespan.

. We're talking about 100 or 200 euros per year! That should hardly make a difference to anyone who can afford to buy a house.If everyone thought like that, all the energy-saving measures like AAAAAA++++++++++ appliances and heating curve optimizations would be completely pointless... after all, you only save 5-10 euros per year, right?
But it all adds up in the end...
P.S. Just by removing the actuators on my heating system, I save about 180 kWh of electricity per heating season, which is equivalent to around 50 euros... it doesn't sound like much, but I'd rather spend that money on something for my child than waste it...
So there is definitely potential for savings even in new builds, especially with the heating system...
