ᐅ Oil heating system approximately 25 years old, storage tank defective

Hello.
We have purchased an old house and have now found that the storage tank is defective. It is a zinc tank with an internal hot water storage.
Since we plan to demolish the house in about 5 years, I only want to invest as little as necessary. Still, heating with electricity is not an option for us. We need about 200 liters (53 gallons) of water per day.
Replacing the tank is also not easy, as it was apparently installed in the attic before the roof was covered, and the roof hatch is only about 45 cm (18 inches) wide. I have tried to draw the current condition in the attachment.
If I understand correctly, the hot water is connected like a radiator. There are no switching valves or similar devices.
Question 1: Is that possible?
Now I would like to install a new tank next to the heating system downstairs. I plan to weld a 3/4 inch connection onto the supply and return pipes and connect the new tank that way. The new tank would have a heating coil. I have one lying around — 300 liters (79 gallons) with a heating coil, a bit large but should work.
Then I would connect the central heating supply and the hot water supply in the attic and separate them again in the heating room downstairs to connect to the storage tank.
Question 2: If I do that, would the domestic hot water be warm enough?
Question 3: Since the tank is no longer positioned at the highest point, or was it placed there at that time because the heating was gravity-based?
PS: Is it still possible to buy a storage tank like the one currently installed?
Thanks for your help, I hope this information is sufficient.

then watch out that the chimney sweep does not shut down the system during the exhaust measurementThe world is ending next week. That would be an equivalent statement.
Sorry, but what am I supposed to make of that statement now?
If you say something, please include a reason.
Thank you.
The chimney sweep mode is not a standard operating program and does not include overheating protection for the heating system; it is intended solely for exhaust gas measurement. The heating system runs at full capacity, and your semi-automatic control is supposed to regulate it each time. I hope you know what you are doing.

I tested this, and it’s also stated in the heating system’s manual.
This heating system has never had any kind of control. It doesn’t even have an outdoor sensor.

Just as an update.
The chimney sweep was here last week and approved the heating system without any issues.
I showed him the remark from this forum, and he just smiled.
With modern systems, it would be different and wouldn’t work that way.
The control system might be interesting, but it has nothing to do with the heating system itself.
What matters is that the heating switches off at the temperature set on the burner, which it does.
The control system operates without any problems.
But thanks for the help.
