Great, It looks like I'll add a new 50 gallon heater to the existing and roll the dice with the warranty issue
I really appreciate everyone's feedback!
Solution #1 would be to put in a larger commercial tank such as an A.O.Smith btr197 which is a 100 gall tank with 197,00 btu.
option number 2 would be to use a raypack or camus boiler with bronze headers and a 100 gall storeage tank. option 3 would be at least 2 bosch pro tanklessunits with a 10 gall storeage tank, AND YES I SAID 100 GALL STOREAGE TANK WITH THE TANKLESS, WE DO IT ALL THE TIME AND THE DISTRIBUTORS RECCOMEND IT.
