Anyone have an opinion on these zone valves?

thx, Pat
 
Hello

In my opinion, zone valves are not as good as using separate circulators, Relays and sweat check valves.

Below is a picture of the Taco 007 circulators, I have been using for over 25 years without ever having a problem!!

So good luck with zone valves!

P.S. The new outdoor reset controller (Tekmar 260) has a DHW priority feature that pops an error if trying to use zone valves because that feature only works with circulators.

Now For a different opinion:
The Honeywell zone valves are fine, some people say they have a high failure rate, but I recently replaced some that were 25 years old, and still working.
energy consuption will be higher running multiple circulators , and you can usually run multiple zones with one circulator for less money initially as well as to operate.
We use Wilo Stratos circulators, Grundfoss Alpha is similar. I have 1 Wilo Startos running 7 zones of radiant in my home ( 7 Honeywell zone valves) priority to the HW, and a seperate circulator for my low temp slab radiant.
They're 2 schools of thought, you need to decide which is for you.

Thats what I'm getting at. I plan on replacing 4 circulators with zone valves, and then using 2 Grundfos pumps, 1 Alpha and 1 variables speed. I plan on running the 2 baseboard zones with the Alpha, and one radiant and my indirect HW on the variable speed pump. The Honeywells are cheaper than the Taco zone valves, I was just wondering if they held up as well.

thx, Pat
 
I have built a dozen plus distribution panels and depending on situation I use zone valves or pumps. Always Honeywell valves because of easy replacement access. Never had any failures. I use taco pumps for same reason with similar results. My thoughts are use zone valves for low GPM flow rates [in-floor type stuff] with a single pump. I will use pumps for larger systems for prim/sec which end up being connected to the terminal equipment. some times it's easier or cheaper to wire up all this stuff with one approach or the other. my personal system has 3 zone valves and about 18 pumps, guess I lean toward pumps.
