Replacing a standard tank heater with an electric tankless oneis easy - you need to pick up the phone and call both a licensed electrician andplumber.
- The plumber will be needed to not only properly size it based onthe temperature rise and flow needed, but to also redo the lines as required.
- The electrician will be needed as the current wiring running to yourexisting one is not even close to adequate. Not only will they need toupdate the wiring but make sure that your existing service can handle theload. (Many require 60 to 100 amps, which many houses can't handle)
With only a few rare exceptions, after crunching the numbersmost peopledecide to go with either a
- gas tankless version,
- a hybrid, or an
- electricMarathon Water Heater which is super-insulated.
