Hi - I'm currently working out what I'll need to provide adequate cooling (in a future proofed way). I'm leaning towards storing enough water in order that I don't need to have a radiator / fan combo. I'm thinking about using 2 x 720L water vessels joined together at the bottom with a pipe and taking the feed to my Still from the base of one of these vessels. The return point will be the top of the second vessel - opposite to where I'm drawing water. I think this makes sense, but someone please shoot me down if not!
A friend believes I should additionally have a header tank - may be 50L to 100L with 2 x ball valves such that the lower one (near the bottom of the header tank) is mains water fed and only kicks in if the pump for the 2 x water vessels breaks etc. and the level drops extremely low. In addition to increased safety, he views the benefit as a gravity feed to the Still (so having a predictable flow). I think I should be able to get a pump which switches on and off whenever the upper ball valve in the header tank demands more water - so it means I wouldn't have a 350W pump always trying to pump against a stopped down needle valve on the Still.
Is all this overkill and unnecessary? I'd really appreciate any practical advice please! :-) I could just go with the 2 x storage vessels and the 350W pump, but then that pump will be always be switched on. Is that an issue?

my only tank is a header tank... 1000L square tote.. Here is a video... I now have a 2nd HX to mount above the existing one, and plan to have the RC and PC separated, and hope to go down to a very small (1 liter) reservoir for the RC, it likes warm inlet temps and the 200kbtu HX does a great job of cooling from hot to warm....

@CothermanDistilling - Many thanks. Just one question about the 200kbtu heat exchanger please. It seems there are a lot of different types of HX and I'm struggling to track down the right type. Are you able to give me a pointer as to the type of HX please? e.g. a web link or Brand / model name
I got that one off of eBay, just get the side outlets, the top outlets look to be a pain unless you are pressurized and purged..
