Effects of the war on construction costs and interest rates?

I have to make a decision in the next few weeks about which heating system to install in my purchased existing property. Until now, I was leaning towards a gas condensing boiler, although I first have to have a line laid from the street to the house for €5000. Looking at the development, I'm currently wondering whether a [Luft-Wasser-Wärmepumpe] with [Photovoltaik] support and a nice fireplace in the large kitchen-living room wouldn't be better.

Regarding construction costs, that also includes heating.
I would install neither a heat pump nor a gas boiler in a new build.

Wood gasifier with large buffer and solar thermal, and that's that.
Of course, you have to be into that.
Personally, I would want to become as independent as possible for the next few years.
And for a new build, that's enough if the wood gasifier runs twice a week in winter.
You do need a bit of space, of course.

Air-water heat pump + photovoltaic is definitely a good solution.

There doesn't seem to be a royal road, unless you set up multiple solutions in parallel - just in case.

Photovoltaics would have to be very large to run the heat pump in winter. Apart from that, the photovoltaic system or the inverter shuts off anyway when the power grid is down. Unless you have an inverter with island mode, which usually cannot supply the whole house but, for example, only provides a Schuko socket (which doesn't really help the heat pump either).

Wood gasifier... yeah, you have to want that. Here in the new development area, there's a multi-family house with pellet heating; that thing is constantly broken, it stinks, and every four weeks the truck comes to "refuel" and wakes everyone up. Surely mistakes were made there that can't be attributed solely to the technology itself, but still... in my opinion, outdated.

Would it really have been so hard to give Russia a contract that Ukraine will not be admitted to NATO for the next 80 (?) years

Russia has absolutely no say in Ukraine, let alone any right to dictate what they have to do. The Russians have always expelled peoples and settled their own population there to maintain their sovereignty. Putin could have done whatever he wanted at the border, but should never have set foot across it. He already applied this tactic once on the Crimea and supported the separatists. Of course, there is also the other side with the USA, and they have enough dirt on their hands, but I am glad that at least someone can stand up to this dictator.

People, seriously now. Last warning.

The pellet heating system in the kindergarten and the parish hall is running. The truck does not come every 4 weeks and there is no smell.
Something is probably not optimally installed in our multi-family house.

I think there is currently no perfect heating system. Energy supply is not smooth, no matter which one. I could also imagine that there will be shortages in the coming years regardless of the war.
However, wood also becomes expensive and requires storage space.

In an old building, I would always treat myself to a wood stove. The warmth is completely different.

Is there a wood gasifier for private use that can really burn everything (with calorific value) and is also allowed? Do you maybe just need certain filters for that or is it always about the combustion temperature? Then with enough space you could go on collection tours. There are really many garden sheds etc. on classifieds to pick up for self-disassembly.
