Steam Heating System Operating Temperature

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building

Flue gas temperature or flue gas loss | Bosch steam boiler …

Economiser. The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
