Wild loop boiler plumbing

Hi All,the subject came up in another post here,what is the purpose of a "Wild Loop" or Rat Race, and should a circulator for that loop run continuously?and you are right it is referring to the other post.

I assume this is the reference post. http://www.doityourself.com/forum/boilers-home-heating-steam-hot-water-systems/573602-boiler-circulator-pump-wiring.html

I read the initial post and a couple of the responses before deciding that I would NOT respond as it would lead to another of my long and drawn out essays. I will have to go back and read the entire thread before I make any definite observations but I can tell you at this time that in an older system (1954) there are very few reasons to keep a circulator running 24/7 or even during the entire time a boiler is firing. Now SOME systems of that era DID have continuous circulator operation but it was not common. Today, however, with boilers that have a minimal amount of contained water it IS necessary to have a continuous flow (circulator operation) to keep the boiler from over heating.

I need to go out for several hours but I will review the original thread and try to post a shorter than average (for me) response when I return.

Won't the aquast prevent the newer boilers from overheating?

Thanks Geochurchi / Gurd.

In case you missed a comment that I had made, the Aquastat stopped the boiler from firing at 180F, but the temperature continued to rise to about 220F.
