ᐅ Which type of heating system is best when replacing a unit after 36 years?

Hello, our newly purchased house currently has an oil heating system installed, which needs to be replaced before we move in.
It is a bungalow with 112 sq m (1206 sq ft). The boiler room is located in the basement. Next to it, there is a welded 4000-liter (1057-gallon) oil tank. Inside the house, there is a two-flue chimney. The previous owners also used a pellet stove in the living room as an additional heat source.
Now I am considering which type of heating system to choose. A gas connection is not possible since there is no gas line available.
My plan was to replace the oil boiler in the basement and additionally install either a water-heated pellet or wood stove in the living room. Possibly solar panels in the next few years as well (although I’m not sure about this yet, as I have often read that the benefits can be limited).
What would you recommend installing? Does it make sense to use a water-heated stove alongside the oil heating system? Or would a simple wood stove for occasional use be better?

Regarding the existing oil tank, it would of course be possible to replace the boiler. However, it might also make sense to consider what will happen with the property in the future. Is the energy certificate based on actual consumption? If so, its reliability for sizing a new system is likely limited.
As Bieber0815 mentioned, it would certainly be advisable to consult an energy advisor who can present you with specific options and plan the system configuration. This is also helpful or even necessary when applying for possible loans and subsidies (KfW and BAFA).

If they are still intact, why? I thought the new radiators are more efficient and energy-saving.

Heaters transfer heat through surface area and temperature difference. If the surface area of the radiator is small, you will need higher water temperatures – that is correct. Unfortunately, I don’t have the efficiency data for oil heating systems based on supply temperatures readily available – you might want to look that up to answer your question. However, I believe it’s not a critical issue.
