Why don’t you like recirculating systems? We just bought a house that has one (my first experience with them) and it is very slick having instant hot water. I wonder how much I’m paying per year for that little convenience.
one, i’ve been told if you have any solder joints it’s not good for them
two, you have to constantly heat that water let alone a costlier system to get it to work and most places electric isn’t cheap, the tankless cut my elecbill by around well over half
three, i can wait for five or ten seconds for the cold water in the line to be replaced by hot water in the kitchen
four, the heater is two feet from my shower head so there in NO lagtime there, ten-fifteen feet from the sink and washer so no real lagtime there
if you have tankless, do you have a holding tank for the circulation?
