Want to upgrade 100amp circuit breaker panel to 200amp circuit breaker panel need an approximate cost

$1400-$4000

This question is exactly like saying "I want to buy a house. How much will it be?"

Giving us a few details, especially like where you live, would help just a bit in narrowing it down some.

Thank you stanfortyman I live in East Hartford, CT I got one other quote at about $2000 I did want to replace a water heater to a takless system project seems to be more cost related than anticipated.

I did want to replace a water heater to a takless system project seems to be more cost related than anticipated. Typical. Folks play up those electric tankless units like they are the best thing since sliced bread.
They neglect however to say that a 200A service is MANDATORY, and sometimes not even enough.
I have wired units that require THREE 40A 240v circuits! That's a lot-o-amps!
