Leigonella breeds like a mofo at lukewarm temps, and is fed by iron oxide (rust) which most radiators experience at some point in time.

great idea, but just be careful, it should be safe for hand washing, but i'd advise against showering as there is a high likelyhood this would create aerosols, which you would then breathe in and put you in real danger of contracting leigonaires disease.

if you have a decent supply of water purification tablets, or bleach, you could chlorinate the water with that and almost eliminate the risk completely

Good catch Binnie,

Appreeciate the advice. I hadn't thought of that.

Soo... it looks like I'll be better off with greater collecting capacity and a smaller reservoir to bring fresh water up to heat quickly on sunny days for immediate use. This is still viable.

I will research the legionella fed by iron oxide issue you highlighted.
All house plumbing now replaced with PP-R piping so no contamination from the pipework itself, but we have high iron content in our non-chlorinated mains water supply. Our strategy for using stored water may need adjusting.

Thanks for the feedback
