We live in a single story home with no natural gas service. We need to move a 50-gallon electric water heater to make room for a bathtub. Our options are to move it to the attic, to the crawlspace, or to a bedroom closet- all with inherent drawbacks. We could also replace it with a tankless heater, but I've heard disappointing reviews and they are expensive. We could lose the heater and use only the second water heater located 50' away in the garage (services the kitchen, laundry and guest bath). I am concerned about heat loss and lag time for hot water to travel to the bathrooms. Saving energy and money is important to us. Any suggestions?
