Install a new oil heating system now?

I have already thought about that as well. On the other hand, many oil heating systems are still being installed, especially in older buildings, and this will surely continue in the coming years, so that there will still be many customers for them even in 15 years. Conversely, one could say that if demand decreases somewhat, the price might also drop...

On the other hand, one could say that if demand decreases slightly, the price might also fall...

... and if the demand for even more electricity and also pellets rises, prices there could also continue to increase.

All crystal ball gazing

Or the providers withdraw from the market and you are left with only one monopolist with exorbitant delivery costs (and prices).

How is the lifespan of the tank system looking?

And to be able to evaluate alternatives: will further energy measures be implemented?

Everything speaks for oil. Cheap, good, and usable for a long time. I wouldn’t let that brat Greta unsettle me.
