Not quite sure what your problem is. You either need mains electric or gas to heat the water - it doesn't work off 12V.

Still doesn't quite make sense.

I assume:-
The 12V pump was working and fed cold water through the taps.
You used 12V pump to fill water heater (which it should have done automatically)
You heated the water using 230V electricity
When the water was hot you turn on a tap and something tripped - was that 230V or 12V?

This sounds like the 12V power supply has failed (or its fuse has) and you don't have a battery fitted. Is that correct?

What make and model of van do you have? What year? Which water system do you have?
