Heating concept for discussion: gas, solar, and wood

Good morning

Why the gas boiler?
With the [them. Solaranlage] and buffer storage, the water-bearing pellet stove is sufficient.

You can then save the costs for the gas boiler, gas connection, and the base fee for the meter.

The ST only supplies hot water roughly between May and September.

That's something at least. Covered for 5/12 of the year.

The water pocket is absolute nonsense at 55... for it to even be of any use, the stove has to deliver a lot of heat. But that contradicts the rest of the house concept.

I don't quite understand that. Since I want to have a wood stove anyway – more for design and comfort reasons – the step to a water pocket is only a small one. Because with a house like that, I don't need a stove to heat the room, unless I want to cook at low temperature or open all the windows to heat the terrace.

The gas boiler is my main heating system. The stove – I currently prefer a stove for logs – is only supposed to be operated twice a week in winter. And that rather for aesthetic and comfort reasons while sitting on the couch in the living room in the evening. And there I would like to make sensible use of the energy of the fire.

I’m getting a gas connection anyway because of the kitchen.

Strike the last sentence and it makes sense [emoji6] Seriously, how much “savings” do you expect with this usage pattern? A few cents a year? The water jackets and the buffer tank also cost money... but mainly, in my opinion, what MyCraft already said counts: it somehow doesn’t fit together - conceptually.

The total costs for your maximum version are already enormous. You have to integrate three different energy sources with their respective temperature levels and need a really large storage tank, probably with several heat exchangers and a pump for each energy source, as well as a backup pump for the stove. Even designing and controlling the system is unlikely to succeed for every heating engineer. A wood stove is probably not going to pay off, whether with or without a water jacket.

Delete the last sentence and it makes sense [emoji6] Seriously, how much "savings" do you expect with the usage behavior? A few cents a year? The water pockets and the buffer tank also cost money... mainly, in my opinion, what MyCraft already wrote counts: somehow it doesn't fit together - conceptually.

I slept on it and the thing about "deleting the last sentence" was a knockout argument for my concept. With my usage behavior of the stove, I will not have any significant gain for hot water production/heating.

I will rather go towards gas condensing boiler plus solar thermal with a reasonable storage.
Wood stove for the look and the feeling of well-being then possibly later.
