Heating combination okay?

Hello,

I plan to install a brine heat pump with ground collectors in the garden (I have a plot size of ~900 sqm), vacuum tube collectors on the south side, and photovoltaic cells on the east side (with a storage battery that could possibly supply the brine heat pump).

In the living room, I want to install a stove with a water connection, basically for heating.

What do you think of this combination?

The cells are to be distributed as follows:

Vacuum tubes on the garage and photovoltaic on the house side.

The picture is just an example image because of the type of construction.

A spacious double garage is planned, so there should be enough space.

Possibly some photovoltaic panels can already be installed on the garage as well, and the vacuum tube area reduced somewhat.

The garage is on the south side and the house side is basically the east side.

How large should both areas be roughly? Are there subsidies for both programs, and if so, which ones?

Thanks

Regards, Michael

I would also provide a uranium combustion chamber and a hamster farm for a Ferris wheel.... so economically it is certainly not viable, but well if it is out of conviction. Always remember to properly consider the [Kontrollierte-Wohnraumlüftung] when it comes to the stove.

What do you think is more economical?

My personal opinion:

Good insulation, controlled residential ventilation with heat recovery.
(properly sized (under NO circumstances oversized)) brine heat pump and photovoltaic on the roof (if you really want to and then possibly already provide space for an energy storage).
A cozy fireplace for the next (short) ice age or simply because it is nice to have one.
No unnecessary technology and no combining of different heat generators. No buffer tanks, etc.
That only makes it expensive, inefficient and prone to errors.

However, you should find a good craftsman and/or energy consultant who advises you independently, have an energy performance certificate done and inform yourself further.

I find a buffer tank particularly advantageous for domestic hot water, and vacuum collectors are especially suitable for this.

With a brine-water heat pump, you have 40 € heating costs per month. ST and tank certainly cost 5T €.... that's already the entire heating costs for 10 years. Think about it.
