Like everything else it depends on your habits. Won't last for two thirty-minute showers back-to-back. Average shower uses about 2 gallons per minute but remember that is a mix of hot and cold water. We get by fine with back-to-back showers using a trick we learned on this forum. We set the water heater to run on both propane and electric at the same time. Think someone on the forum termed it "turbo heating". When we are finished showering, we set it back to just electric. I don't think it will be as big an issue as you think.
