I have a 20 yr. old Rheem low boy 40 gallon gas hot water heater (about 36 inches high)
In my crawl space. I've found out they don't make that size anymore in 40 gallon size-only comes in 30 gallon size now. I don't know whether I should get a 30 gallon gas one or go to 40 gallon electric hot water heater. Am not handy and wondering what would be best option in regards to price, energy efficiency and being able to provide hot water for a home with 1 and 1/2 baths - only one shower/tub. The hot water heater still works but afraid it will go out one of these days. Also, not sure if I have enough electricity to support an electric one.
