Boiler Water Loops | HVAC Hydronic Piping Systems

As far as I know water is it for boilers whether it is hot water or steam. And I dont think the issue is corrosion much as it is a mineral problem. With steam boilers it is super important to flush it or blow it down weekly and with hot water boilers it is important to flush the system from time to time.

Domestic Hot Water Re-circulation Systems - Ron George

If the system has 140 degree water in the water heater then the sizing method maintains 130 degree hot water at the end of the system and then back at the cold water inlet to the water heater the temperature would be approximately 120 degrees. The calculation is based on heat loss in the hot water piping circuit.
