Hello: I’d be thinking about where the pipe goes. What path does it take to get from the heater to the shower? Is it short, well insulated and inside of conditioned space (best case)? Or, is it long, poorly insulated and running in a vented attic or crawlspace … or worse, running in the ground? You’re likely somewhere between these two extremes, but you can see that the more the pipe is exposed to cold conditions, the more heat loss must happen between heater and shower.
The best system is made of pipe that will just handle the required flow and no more. This reduces the volume of water in the lines. It will be run in the conditioned space, to reduce heat loss. And, it will be better insulated then most people feel it needs to be 😎 Energy prices do keep going up… When is the next time the insulation will be upgraded?
So, it’s not a naive question at all. Plumbing systems are given too little thought. We can make them perform DRAMATICALLY better with good design and installation.
