Indirect with steam

You need a flow check on both the supply and return lines, isolation valves, unions, drains, a bronze circulator and a relay to operated the circ, and a MANUAL air vent on the tank. Most boiler manufacturers provide the piping diagram to do this. If you don't have it, see Weil-McLains site and go to piping diagrams. We do this a lot and it works very well, and makes a ton of hot water.

    Indirect with steam

    I want to put an indirect on an existing steam boiler and would like to know what controls I would need to make it work properly. I believe I just need to make sure the aquastat is below the water level with a high limit set at 180 degrees but what else do I need to do for this? Thanks for your help in advance.
