There will be a switch for the water heater to use electric or propane, if you are on shore power use electric. I only turn my hot water on shortly before I'm going to use it....I see no point of heating water all the time if I only need in for dishes or a shower.
Agree with above except the teflon tape addition. You need to confirm what brand you have first. If it's a plastic plug (Attwood) then yes you can add teflon, if it is a Suburban brand with the anode rod then by no means do you add teflon as the metals need to make contact to eliminate the electrolosis that takes place. The plugs have pipe threads so the harder you turn the tighter it gets.
Best to also pop the blowoff valve to confirm you are full. 20 seconds on electric with no water will fry the elements. Just because there is water coming from the hot side of the tap does not mean that there is hot water going through the heater.
