Hello,
I am planning to install a ground source heat pump with horizontal collectors in the garden (property size approximately 900 m² (9700 sq ft)), vacuum tube collectors on the south side, and photovoltaic panels on the east side (including a battery storage system that could potentially power the ground source heat pump).
In the living room, I would also like to install a stove connected to the water heating system to contribute to the heating.
What do you think about this combination?
The panels are planned to be distributed as follows:
Vacuum collectors on the garage roof and photovoltaic panels on the house side.
The picture is just an example because of the design.
A spacious double garage is planned, so there should be enough space.
It might also be possible to install some photovoltaic panels on the garage roof and reduce the vacuum collector area slightly.
The garage faces south, and the house side is practically the east side.
How large should both areas be approximately? Are there any subsidies or incentive programs available for both? If so, which ones?
Thank you.
Regards, Michael

My personal opinion:
and no combining of different heat generators. No buffer tanks, etc.
That only makes it more expensive, inefficient, and prone to errors.
What makes you so sure to present this statement as universally valid?
Olli
You even quoted the sentence that actually does not make the statement generally valid.
But for most single-family homes, the following applies:
Expensive: Combining different heat generators when only one is sufficient.
Inefficient: complete oversizing of the living unit by combining all generators, which rarely or never operate simultaneously.
Prone to errors: three different heat generators that all need to be combined instead of one heat generator perfectly matched to the heating system. Hmm, that’s true. That rather supports the combination.
The forum as well as the internet are full of further reasons.

What do you think is more cost-effective then? It always depends, of course. In your case, the initial investment is so high that it will probably never be economically viable. Ideally, you should invest significantly less, meaning just one heat generator (in my opinion, a gas condensing boiler would be best, but that alone is not legally allowed; with solar thermal, it might again become less attractive compared to an air-to-water heat pump. Perhaps a gas condensing boiler combined with controlled residential ventilation could work — an expert needs to calculate that).
A trench collector with a brine-water heat pump is already a good start. You can get an additional 4500 € subsidy. Operating costs are practically unbeatable.
If you want to invest a bit more, consider photovoltaic panels – the screed acts as a buffer storage for the photovoltaic electricity.

Yes – screed has a high thermal capacity and can store a lot of energy (much more than 1000 liters (264 gallons) of water can – simply because there is a much larger amount). Then you raise the heating slightly around midday and lower it again afterwards. Without this kind of approach, even photovoltaic systems are no longer cost-effective at 12.5 cents/kWh.
