Skull thumpin' the Designers
I'm involved in an upgrade project that is a conversion from a steam system to a hot water system. I made a request of the design team to install the boiler circulator on the discharge side of the boiler, "pumping away". Their response was,"normally the pump is installed on the inlet side of the boiler in order to pressurize it to reduce air sepration." Am I mistaken or isn't that one of the reasons for "pumping away?"
