So, you need to hire an electrician to install a new high amp circuit and to run it to the water heater location. And, sometimes, the electrical panel will not even accommodate the high amp circuit breaker, so you need to upgrade the panel. In most cases, it makes more sense to just replace the existing tank type water heater with another tank type unit.

If I did all that. Would I be saving the planet? I doubt it.
