Okay, six+ amps.  Ignoring losses, it will take about 18 hours to heat 13
gals of water 40 degrees F. (i.e. 50 litres by 22 degrees C).  In the same
time you could heat a 600 lb block of concrete the same amount, or melt 30
lb of ice, or evaporate about 2 litres of water.  It will take about 150 ml
of gasoline, or 2/10 pound of natural gas, or the energy in a roughly 75
pound deep-cycle battery (not realistic, it would take about 110 amp-hours
which I think would require a bigger battery in practice).
