Help with hydronic heat

[Jerry Ning]

Hey all, I have trouble finding hydronic baseboard heat expansion carriers that fit my slant fins. I've attached a picture of the old ones and the expansion cradles I bought online. Can anyone recommend where or what to do about expansion noise?



Thanks
Jerry

Running the hydronic system with nearly continuous flow at low temp using an outdoor reset mixer can reduce or eliminate expansion noise and increase comfort & efficiency to boot. With that type of control setup there are never rapid changes in water temperature or room temperture.
