Hi, I've just finished my Thermo Valve project.
 
The objective was to convert a Bosch washing machine & Dishwasher to a solar hot water feed to save my batteries & PV load.
 
The YouTube link below has all the details, but in essence. If you want to reduce electrical load form heating water, and you have excess solar hot water, this makes a MASSIVE difference to reducing electrical consumption.
 
FYI, it's not possible to select a totally cold wash on most modern washing machines.  If you disconnect the element on these appliances you tend to fool the microcontroller (waits to get up to temperature forever) it took 6 hours to complete a 15min wash. Dishwasher need around a min of 45Deg to wash & dry plates. 
 
Hope you find this Video informative 
 
Total outlay was about R650 for the TP Valve,
R 250 copper fittings. 
Lots of time in the attic, chooses a cold day, or a good way to loose a Kg.

Hi Everyone
One thing to be aware of is, any uninsulated battery terminals, especially when they are close together, become instant welding machines if you happen to 'drop a spanner in the works'!
A bit of shrink sleeving over those Bus Bars could save you some heartache and avoid a fireworks display.  Don't be fooled by low voltage there is still massive current.
