You don't think this degree of insanity is a passing phase?
I've been doing it for years...

Legionella are bacteria that are common in natural (rivers and lakes etc) and artificial water systems, eg hot and cold water systems (storage tanks, pipework, taps and showers).

Legionella can survive in low temperatures, but thrive at temperatures between 20oC and 45oC. High temperatures of 60oC and over will kill them.

Legionella bacteria can multiply in hot or cold water systems and storage tanks and then be spread, eg in spray from showers and taps. Although the generally high throughput and relatively low volume of water held in smaller water systems reduces the likelihood of the bacteria reaching dangerous concentrations.

A slight digression... Wouldn't the chlorine in mains water in a home setting negate the need for higher temps to kill them?  We have our thermostat on the hot water tank set to 55C.  Hasn't killed us yet.  But it's a small tank and probably the whole capacity (if not more) is cycled daily.  Our shower is a cold fed electric one so the hot tank has nowt to do with it.

Crib what we used as a "demo" at festivals - solar panel, insulated tank, gravity fed with cold water from a small storage tank with ballcock - TMV on the hot tap to save scalding - no electrics, no pumps - job done! (just use a simple "scaffold" to hold the tanks.......) - the order (from the top) is cold storage tank, insulated storage tank, solar panel (s) - taps below the level of the bottom of the storage tank - THAT simple!

Not sure if my PM went through, so asking here as well...how much does a system like this cost?  TIA

we used one of these (insulated tank and tubes combined) - around £400 - http://www.navitron.org.uk/product_detail.php?proID=115&catID=116 - added to that a small storage tank, some piping, taps, tmv and insulation - even if you bought the whole lot new including some simple scaffolding, well under £1,000 all-in (we did it for under £600)

To make it really easy, we mounted a board on the reverse of the unit with a simple bowl with taps over it, and the TMV attached  - then a simple scaffold with the "feeder" cold water tank........
