hartford loop

Paul Diduk

Went to look at a 4 year old peerless steam boiler this weekend.... On call... And noticed that the Hartford loop was about two to three inches above the water line. I know what the peerless manual says 2 inches below water line... told employer about it they said no big deal its been ok for years... want to know for my own knowledge what can happen to this persons boiler...really cant find a good answer in any of the books I have

Thanks Paul

It's the return piping

Paul,the loop was designed so that in the event of a return line leak the boiler water couldn't drain completely out and the next thing would be a glowing boiler, this was in the days of boilers blowing up often due run away heat and lack of lwco's that worked. Some old boilers even had a plug over the fire box so if this runaway fire got to hot the plug would melt causing the boiler water to drain out and put the fire out. Today with proper low water cut offs steam boilers are fairly safe. While the piping you saw isn't perfect I don't think it's a pressing concern.John P.S. I'm sure others will disagree about pressing but, like your boss said been like that for years, try to get someone to pay to repipe it now lol

It is still protected from low water even if it is above the water line. They may have water hammer when the condensate hits the steam in the equalizer.
