How to Take Care of Your Radiators - Old House Journal

If you have steam heat, each of your radiators will have either one or two pipes. All steam radiators take advantage of gravity to get the condensed steam (called "condensate") back to the boiler. The key to making it all work is to keep the system pressure low. If you can't heat your old house with 2-psi pressure or less (that's the pressure

Hartford Loop - MassEngineers.com

A Hartford Loop is an arrangement of piping between a steam boiler's header and its gravity-return piping. The end of the header drops vertically below the boiler's waterline and connects into the bottom of the boiler. We call this pipe the "equalizer" because it balances the pressure between the boiler's steam outlet and condensate-return inlet.
