Storage How do I size hot water storage for my system

[Guastini]

My question is: How do i size for enought hot water storage?
I am about to head into year 2 with my EKO 60. My house is about 3800 sq ft, one level, mostly new so new insulation, new windows, radiant floors. I am interested in saving wood. I Went thru about 8 cord last year Christmas to May 1. I also want to add solar thermal and not spend any more money on oil in the summer. I have just found a 1000 gal former propane tank ( submarine style) for cheep. Is it enough? and if so can anyone point me in the right direction to prep it to use?
thank you !

if the mods will move this post to the boiler room you will have better luck getting an answer, I'll take a stab
1,000 gal should work for ok storage, more is always better, you need to get the tank cleaned out, there have been other posts of how some have gotten the stinky stuff they add to gas out. then you need a stand pipe on one port, a pipe that will go to the bottom of the tank, the other port should feed right up at the top. you will also need an expansion tank if you run this tank pressurized, which is the best way.
