I can run cables from the sub-panel in the garage if necessary.
It was a 3kW unit I was looking at. My major unknown is whether the unit will supply the water I need for the durations involved in the washing steps...tempered water for long(ish) durations, i.e. low flow situations.
I have exactly zero experience with such units.
