I'm bidding a new house piping job and they want to install a Rinnai propane tankless water heater. How are you guys piping them as to NOT reduce the warranty from 12 to 3 yrs? I see installing a small tank heater as defeating the whole purpose of installing the tankless in the first place. Should I install a 6 gallon storage tank in a loop and an on demand system? i.e. the bathroom light switches activate it? The lines are all going to be installed lower then the water heater so a non-pump system will not work.
No announcement yet.
New house recirc system?
