I am remodeling my master bath, and we will have a spa shower and a whirlpool tub. I am disabled, so my showers tend to be fairly long ones. I was told by moen that my shower valve will flow 5gpm @60psi. My showers tend to take near 20 minutes, so I think I would need either a tankless or multiple tank type water heaters.
I have spotted the bosch 250sx at home depot, and am considering that. We live in central NY, so the winters get fairly cold...so I know I would need the 250sx over the smaller model since I imagine the actual temp of our cold water is pretty cold in the winter.
