ᐅ Heating System Combination OK?

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

I would also include a uranium combustion chamber and a hamster farm for a Ferris wheel...
So economically, that’s definitely not viable, but it’s fine if it’s done out of conviction. Always remember to properly install controlled residential ventilation for the stove.

What do you think is more economical then?

My personal opinion:

Good insulation, mechanical ventilation with heat recovery.
A properly sized (definitely not oversized) ground-source heat pump and photovoltaic panels on the roof (if you really want them, and possibly already plan space for an energy storage system).
A cozy fireplace for the next (short) ice age or simply because it’s nice to have one.
No unnecessary technology and no combining different heat generators. No buffer tanks, etc.
That only makes it more expensive, inefficient, and prone to errors.

However, you should find a good builder and/or energy consultant who can provide independent advice, carry out an energy performance certificate (EPC) assessment, and make sure to inform yourself further.

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

With a ground-source heat pump, your heating costs are 40 € per month. The solar thermal system and tank probably cost around 5,000 € (about 5,500 USD).... that already equals the total heating costs for 10 years.
Think about it.
