Purchase of an existing single-family house prefabricated house year built 2000

Again regarding the heating, since we still have a building savings contract that will be ready for allocation in 2 years with a savings amount of €25,000, the heating system would already be largely covered by it! Since the house is already a low-energy house, initial research suggests it should be sufficient to replace the radiators with low-temperature radiators, which would also make a heat pump possible. It is not due yet and I still have plenty of time to think about it, who knows what our Green government will pull out of the hat! I always wonder where all the electricity is supposed to come from, but let's leave it at that, otherwise it would get too political!

As someone who just moved out of a new building with a heat pump, temporarily into a poorly insulated old building with an oil heating system: I wouldn't put off renewing the heating system for too long. We were lucky that there was still some left in the tank (and it was family-owned). We then reordered the rest in the summer to get to about 3000L for one heating period, if we were lucky. If the tank had been empty and we had to buy 3000L, it would have cost us 4650€. That's almost 400€ per month for heating oil, and that might not even be enough for a year.

The purchase price must be with the seller 14 days after sending a written notification from the notary... if the following conditions are met:
- Priority notice of conveyance...
- Pre-emption rights...

I have seen the bills, a maximum of 1500 liters was needed in the year with 4 people, and without additional heating with the wood stove! Since we will be heating a lot with the wood stove, we will probably even need less! According to the energy certificate, the consumption was even only 900 liters, but that was issued by the previous owner! As far as I have currently estimated, a heat pump would not be financially worthwhile at the moment! Especially not with electricity prices at 60ct/kWh!

Why do you assume that you will heat more with the fireplace than the previous owners? Or what was the reason they didn't use it?

Well, with 1500L it's not so dramatic anymore. The house is certainly better insulated than ours. But it's still 200€/month for oil.
