After some recent work, I have a question.
I replaced all my copper with CPVC (100PSI @ 180F). Except at the boiler.
I went from CPVC to copper then went to the thermal trap, DHW coil and the cold side of the tempering valve, then another thermal trap. Only then did I go back to CPVC.
My question is... Why bother? Couldn't I have just used CPVC for the whole thing? My boiler runs at 180F and water pressure in my house is about 50 PSI. As it is now the CPVC pipe will never see temps above the tempering valve setting.
Any thoughts?
