replace gas with electric water heater
I have a leaking 40 gallon 40000 BTU/hr gas water heater in garage open area, at home for 2 adults in San Jose, CA.
I am looking into to replace with 40 gallon 4500W electric water heater.
So I need to run 220AC extension for around 5 feet, wall socket, and breaker. I also like to add shut off timer so that I only run the heater 12 hours instead of 24 hours every day. So far, I do not find this timer at Home Depot.
What kind of work time and approximate cost for electrician to do this work?
