Question on efficiencies with a two-tank domestic hot water desuperheater configuration. I've seen a couple piping diagrams with buffer tanks (here and here). I'm curious if a direct-load configuration (discussion here) would benefit a Desuperheater similarly to a standard heating load. Since the DSH runs when the heating load is called, the intermittent cycling should be a factor, right? For ease of discussion, I've attached a few diagrams and given them names. Direct Load - A configuration from the Buffer Bypass thread, John Siegenthaler's article, and other sources. Partial Direct Load - Prioritizes hot water at the top of the tank, the HWH pulls from near it's input Indirect Load - the recommended buffer tank configuration from the two linked sources above. For context, I'm a DIY-er planning my install using hot water heaters as buffer tanks (no dip tubes). This forum has been a huge help. I've really appreciated combing through it to learn for the past few months. Thanks!
