If you run both electric and propane at the same time- once the tank is
hot the electric will still cycle to keep it hot. The propane usually doesn't come
on unless you use a significant amount of hot water.
So yes the hissing will still be there probably!
Plus you'll hear the sound of the burner if it does light.
I'm guessing the water heater was further away from the bedroom
in your previous trailer.
By the way it's perfectly OK to use both modes of heat at the same time.
Folks often do that so they can get the water heated faster.
I'm a tight wad and so I don't use propane for heating water unless
we don't have electric hookups.
