Anyone come across any good & cheap options for an HLT?
As the subject like states I'm ok with proper plastic options that won't leach anything at 80C degrees. -Insulation is a bonus but obviously not required as it can be easily added later.
I'm looking for a tank that is narrow and tall to reduce the amount of heat loss to the air, to ensure a good convection current while heating, and because I'm going to install a copper coil in the HLT for a HERMs system.
This is the best option I've found so far; if I could find somewhere in Seattle for local pickup, I think I'd definitely go with it: http://www.tank-depot.com/productdetail ... e&optname=
On a related note: Anyone know of a cheap pump that can be safely used with 80C water only? (I don't want to have to buy a $100 chugger pump just to recirc the water in my HLT to aid heat transfer in the HERMS coil.)
-What sort of pump rate is appropriate to recirculate a 20 gallon HLT? (It'll probably only have 10 gallons in it while the HERMS is in operation.)
