Here's the power draw for a heat pump water heater. It pulls about 400-500w most of the time. However if the tank gets really cold it'll use the heat pump AND electric heating elements. In this case, I swapped the 4500w elements for 1500w elements so when they are on they don't pull too hard on my inverters. It ran the electric heat for about 10 minutes this morning and went right back to heat pumping.
