Hello, I am currently planning our house. A brief introduction: we are building in Lower Bavaria.
We do not want a basement, and the house should have about 220 sqm (2,368 sq ft) of living space in total.
I work part-time as a farmer. We have a 29 kW photovoltaic system on our barn, which is connected to my parents’ house.
In the living area, we want either a tile stove or a wood-burning stove since we have our own wood supply. A wood chip heating system is not an option for us.
What would you recommend installing currently? I saw a stove from SHT that can burn both pellets and logs. The advantage would be that we could avoid having both a tile stove and a wood stove.
I’m not quite sure at the moment... I would really appreciate your advice. Best regards

Those would be good conditions for a ground source heat pump with a horizontal/loop collector. Especially if you can do some of the work yourself, you can come out ahead thanks to the subsidy (BAFA 4000€). But a heat pump doesn’t really go well with a fireplace that supports the heating system (in my opinion, the latter only benefits the seller’s wallet and the user’s sentimental attachment)I’m not so sure about that because my garden layout depends on not having larger trees, shrubs, maybe a pool, and so on—all of which have to be considered..... Best regards
Yes, that is not quite correct. My acquaintance installed the collector in a trench just one meter (3.3 feet) from the property boundary. It is also deep enough so that you can safely plant above it. However, the pool cannot be placed over it.
That said, you could heat the pool using the heat pump and power it with photovoltaic panels in the summer at no extra cost.
Please don’t dismiss everything right away without gathering information first.

toxicmolotof3 Jan 2018 02:52Cost-neutral does not hold true in summer either. The system has to be paid for, the consumed electricity is not reimbursed by the grid operator, and the value-added tax as well as the complimentary supply to the heat pump must also be taxed.
Overall, photovoltaic electricity costs about the same as electricity from the grid (plus or minus a few cents).

The trench collector is still relatively unknown in Germany. There is a home builder here that practically uses it as a standard (whatever the details behind it may be). In my opinion, it is especially worthwhile if you do the trench work yourself.

readytorumble3 Jan 2018 11:16We also installed a ground collector ourselves.
We needed about 350m² (3750 sq ft) of area and laid 650m (2130 ft) of piping.
The work took around 8 hours with 4 people (an excavator operator, my fiancée, her brother, and me) spread over 2 days.
I estimate the cost at a maximum of 1000 euros!
The shaft where the brine pipes converge and where the manifold is located was somewhat more complex. For that, we poured a small concrete base slab (2m x 1.4m) (6.5 ft x 4.6 ft), set concrete blocks, and filled it with concrete, then poured a cast-in-place concrete ceiling on top. This took about 30 hours, and I estimate the materials cost around 600 euros.
It can be done simpler or smaller, but since we built the entire heating system ourselves (a family member is a professional), we wanted the shaft to allow for comfortable working conditions. The brine pipes are extremely rigid, and connecting them to the manifold in a tight space is even less enjoyable.
Among acquaintances, there are other ground collectors with gardens or trees planted on top. You just have to make sure not to build anything over them.
