Boilers | Why return condensate to the boiler? The best

If condensate isn't returned to the boiler, the steam system must make up the loss with cold, untreated, raw water that has to be prepared for boiler operation. This preparation has a cost. The make-up water also contains substantially less BTU content that must be raised in the deaerator or atmospheric feed water heater.
