Not dismantling the oil heating after all?

Do you know what costs you are talking about?

+/- 200€ annually. You can buy a lot of electricity for the heat pump with that. And without the oil heating system, you also have more space in the basement – the tank and heating take up a lot of space. The disposal is also heavily subsidized.
==> so get rid of the old junk

P.S. By the way, to receive the subsidy, you are no longer allowed to use the old oil heating system. It may only remain as decoration at most.

That replacing an oil heating system is advisable goes without saying. But certainly not in the worst chip and material crisis we have experienced so far at absolute fantasy prices from manufacturers and installers...

That it is necessary to replace an oil heating system is beyond question. But certainly not in the worst chip and material crisis we have experienced so far at the absolutely fantasy prices from manufacturers and installers...

However, the question from the OP was not whether he should take action now, but whether he should continue running the oil heater in addition. And I answered this question. And pointed out that he will not receive any funding if he keeps the oil heater running.

Otherwise, I do agree with you, of course, that right now is not the perfect time. Even though prices in construction overall have already come down significantly recently.

There will also be funding next year. Otherwise, no one could afford this whole thing. As I always say, the classic home builder/owner does not have 10,000 EUR net per month, this forum distorts many things because many people here have money. And as already mentioned... anyone who orders today will not get the heating system installed in the next heating season anyway. Impossible, delivery times were already 35-40 weeks at the beginning of the year.
