Okay, first I'll say I am aware of the shortcomings of Tankless units. But I have lived with one for 7 years and not had a problem with it at all.
I love the stupid thing!
BUT! I have been using it in a cabin/makeshift setting where I simply had Cold water pumping into it and out to a shower head. (no valve and no cold to mix into it)
Well I am about to do the plumbing to the bathroom in my new house and it's going to be a right proper shower with hot AND cold runnin' water!
My concern is what effect a pressure regulating or thermostatic valve will have on the Tankless.
(my preference would be to have old school manual valves hot and cold and the two simply meet and mix but these are no longer allowed by code....the tankless already serves as the scald protector as it is set to a specific temp and never fluctuates)
Anybody have some advice?
Thanks a bunch.
