I've decided to replace a LP Gas Tank water heater with an electric tank water heater. In a 3 bath application where for the most part one bath is full
time and the others only for guest. The baths all withing 10-15 feet of water heater and each other.

I have a couple of options:

1. One Large single electric tank water heater.

2. Use a seperate electric tank water heater for main bathroom and one for the two part time bathrooms, kitchen and laundry.

3. Combine a pre or post heat electric tankless in combination with the tank(s).

Suggestions? Options?
