    It’s more efficient because there is no heat loss thst a tank suffers from even if it’s insulated. It takes the same amount of energy to heat up water b N degrees. Doesn’t matter how fast you do it. The real drawback is that it requires a much larger breaker and will likely need to run new wires. It may be an issue with your electrical if your panel doesn’t have enough leeway.

      That makes sense. As for the breaker if you’re using gas it actually runs on a standard 15-amp circuit (I have one), but it does require a potentially larger gas inlet which can be costly too, and you need a 4” exhaust which may require some retrofitting too.
