Hello,
Should a grundfos water circulator for a single zone hot water system be near-silent? Is there any good way to ensure that it is working? My parents taco cirulator (5 zone system) makes a bit of noise so you an at least know its running, granted it is a much larger motor.
Also, does the I, II, III settings get chosen based upon how many stories you have in your home?
I get heat all over. However I doubt that when the house was originally built, there were hot water circulator pumps in the system (just gravity).
Any thoughts???
Thanks,
JMH
