Sizing boiler feed units vs. condensate return units

Mar 28, 2016 · Boiler feed units are generally sized for 5 minutes of net storage. You can feed your boiler for 5 to 10 minutes, depending on the load, to keep it steaming while waiting for condensate to come back. In smaller systems, up to 150,000 sq ft EDR, 5-minute pumping capacity is a good rule of thumb. For systems larger than 150,000 sq ft EDR, 10
