Query: Aquastar 125B

I don't like the fact that it sporadically stops heating partway into my shower. My gas line was increased (and from a high pressure supply, regulated down)- it did not help. The water pressure is 45 psi. I cleaned the inlet screen - it was essentially clean anyway. We don't run anything else when showering.Other than taking up less space in the furnace closet, this thing has no advantages for me.
