TT states the 60 needs at least 3 gpm on full output.
Everything is dialed way down with the outdoor reset and a maximum setting of 120F. I’m saving gas compared to the 1974 National cast iron behemoth I replaced. I thought I would try to cut power bills for pumping as well.
I’m on a fixed income with an occasional stimulus check lol. The Wilo has apparently been discontinued? Any reports on performance as a boiler pump? I’ve doubled down on sediment collection and flushed the old cast with fernox. I taped hard drive magnets to my dirt separator and the hydraulic separator too.
I enjoy looking at all the do it yourself installs and comparing them to what Siggy would have done.
12x pipe size straight pipe upstream from a pump seems to be missing from a lot of these creations.
