Is it feasible to connect two hot water heaters to one fixture?
I've torn everything out of my second bath and when
I connect up the new tub, I'll be using hot water from a different
water heater so that this bath doesn't share the same hw heater
as the master bath.
I wondered though if it is possible to connect both the original
hot water line and the new one into a T, then into the tub hot water
line? The idea of course being that there'd be almost twice the
available hot water. Seems logical, but I guess I'm expecting a pro
to tell me about some backpressure issues. What say ye?
