Tricky question. Water will obviously boil and turn to vapor (steam) at 100 degrees celcius (212 F). But if you heat water to a point below boiling, you can see it giving off steam. The temperature at which that happens is not fixed;it varies with the ambient temperature and humidity.
If system requirements are for hot water of more than 250Â°F, a high-temperature water boiler should be considered. Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications.ost steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.
