The first being that tankless heaters cost money ,what I did cost me nothing, I already had everything that I had salvaged from jobs. Even if I had purchased everything it would have been under $20 and possibly under $10.

Second, my electric supply wouldn't handle the amp draw from a tankless heater, you have to have enough power available to instantaneously heat your water flow..

For instance, a Rheem RTE 13, about the minimum size to supply a single shower, draws 13kW at 240V, I only have 120V and about 3kW available..
