Proper Boiler Feed Water Temperature Management | Powerhouse

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.

Steam Heating System Operating Temperature

Relationship of Boiler Pressure to Water Temperature in Steam Boilers. The temperature of heated water can exceed 212 °F when water is heated under pressure - producing superheated water than can flash to steam. See BLEVE EXPLOSIONS for details. 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.

What Pressure Should My Boiler Be? | Vaillant

As the boiler heats the water within the central heating system the increased temperature causes the hot water to expand this results in a pressure rise. The rise in pressure can be identified from either a digital or mechanical pressure gauge on or in the appliance.

Steam boiler pressure and brew temperature for HX espresso ...

Apr 14 2015 · When the boiler pressure was set to 1.0 bar I could do really short flush like 2-3 ounces and brew right away. With the boiler pressure set higher (1.4-1.5 bar) the water is flash boiling when I flush. So as soon as the dragon stops do you think the brew temperature is ok or it might still be too hot ?
