the 12v went fine Norm. Not a great amount of pressure, but enough. I had a 55 l tin rubbish bin (new) filled with water warmed up on the stove - went through the 3/4 full bin in 5-6 minutes.
Good enough shower
Not sure what kills the hot water systems - its never the tank that goes but the electrics, but will sure ask the installer tomorrow.
Was tempted to just go to bunnings and get a new system and put it in myself, but insurance problems and all that
Had a look at the v40 i picked yesterday fixed rusted starter pawls, adjusted valves, sprayed up the main jet (carby full of red water), went first pull and ran perfect, so i didn't have the heart to kill it off because of rust - so i cleaned it a bit, looks ok
