How you doing?
Drylok sounds amazing. Although we dont have it here in Cyprus. Also would you be concerned about pollution using a product like Drylok?

IF - I were to go with a design with a coil... How does this sound? What if I built the system above and plumbed the sinks and washer to it - but included a coil inside the batch tank that just fed the shower....? AND - what if the water from the coil then flowed into a seperate "closed" (?) tank so as to have more volume available for shower...?
--- Thoughts on tank sizes in any of these scenarios?

I get that the hot stuff will be on the "top" - but, as a non-pressurized set-up, I will have to pick a point on the side of the tank - right? -- So, essentially, if I used a 20 gal drum and put the outlet a third of the way down the side, I might have 6 or 7 gallons of "really hot" water before the temp starts decreasing much - right?
And it just seems like if "stuff" grows below 150 degrees, I shouldn't be using it if the temp in the tank goes below that - ? At what point in the tank would you measure the temp of the water?
Thanks! - You guys are GOOD!

Okay - Holidays are over...
I'm leaning toward something like this: http://www.builditsolar.com/Projects/WaterHeating/CostaRicaThermosyphon/CostaRicaThermosyphon.pdf
- unpressurized - float valve - plastic tank of some sort - PEX pipe.... There is no normal hot water heater in the house. What I build will only supply a shower and a sink.
I'm not to worried about water that's "too hot" - only used by adults and there will be mixing valves at each spigot.
USVI is pretty much 70-90 degrees year-round. From what I read I should have no problem keeping it above 150 degrees, but bacteria makes me paranoid...
So.... the storage tank will have a "temp gradient" - right? What do you expect that range would be from bottom to top?... What is the location of the hot water outlet pipe? - top 3rd of tank - maybe?
Should I install a temperature sensor and gauge somewhere?
