Milktank at unit EC 20

For years already we have problems with our central heating system.
Now we are planning for a low cost idea: we have a plan to use the old emergency feedwatertank of the (already scrapped) auxiliary boiler of unit EC 20 as a buffer vessel for the heating system at units EC 3-7.
So I had to take some pictures because "one picture says more than 1000 words" as I heard...
We are planning to shift the tank all by ourselves; quite a challenge!
Looking forward to it...

Better in LARGE.....

I was here before.... look!
