Replacing the heating elements, in the heater is not complicated but you will need someone who knows what they are doing with the electric heater.

An 80-gallon electric tank is going to take a lot it will take close to 2 hours. You should pick a tank size that’s right, for the amount of hot water your household uses. If you get a tank that’s too small you will run out of hot water very fast. If you get a tank that’s too big like an 80-gallon tank you will be waiting around forever for the water to heat up.
Initial Water Temperature
The colder the incoming water is, the longer it takes to get hot. If the water coming into your house is 50°F or colder the water heater has to work a lot harder to get the water hot. In the summer the water coming in is warmer, like 70°F so the water heater can get the water hot quicker. This makes a difference, in how long you have to wait for the water to get hot and it can add 30 to 90 minutes to your wait time depending on the time of year.
Energy Source and Efficiency
Gas heaters heat faster than electric ones because they put out more BTUs. That means a gas heater might get your water hot in 30 to 40 minutes while an electric one takes way longer. How efficient your heater is also matters. Newer, more efficient models heat water faster and don’t waste as much energy. An old, beat-up heater is going to be slow no matter what fuel it uses.
