Years ago I found that drinking coffee gave me constipation so I switched to cold showers to give me that 'morning wake up'. That has worked ok because my water heater is so far away from the master bathroom that even when I turn the shower valve to HOT I still get cold water. That's fine for my wife as she would then have instant hot water when she got up a little later.
But now I'm sleeping later and my wife now gets up first and wants hot water instantly. So I'm thinking about getting an on-demand water heater installed near the master bathroom . I would have the main water heater set at 130F and the on-demand unit set at say 110F so that when the hot water reached the on-demand unit, the on-demand unit would turn off because the inlet water is already hot enough.
My main water heater is on a 30amp 240v circuit and the on-demand unit requires a 50amp 240v for its max heat (which would never be used at max).
My question is can the two units run off the same circuit if I upgrade the 30amp 240v to a 50amp 240v?
PS I will be buying a used on-demand unit fairly cheap.
