Can anyone recommend a tankless on demand water heater?

I'm currently on 30A and would like to fill a soaking tub with hot water if possible. It would have to be hard-wired into my breaker box. I'm wondering if that's possible with the amps I have to work ...

20 amps x 120 volts = 2400 watts.


Unless you enjoy barely warm water.....a 20 amp heater is not going to do the job. It may be too much to ask of even a 50 amp RV.

The link provided suggests it may work for hand washing applications, and wants 3000 to 3500 watts.
