Warm water on tap post soft

you've got to be seriously careful with lukewarm water that isn't chlorinated. especially if you leave the radiator full of water.

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
