I added about 2 litres of boiling water from the caravans kettle, and it was warm enough to use.
It worked a lot better than I expected, strong enough flow to get the sand off and I used less than half the water in it doing so
Main problems I had - no trees nearby to hang it from, no where on the caravan to hang it from, getting it onto the caravan roof wasn't easy
