By adding hot water storage, the system designer can achieve an energy efficient
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.
For combined heating hot water and domestic hot water systems, when the heating hot water system exceeds 140°F the IPC code requires a temperature actuated mixing valve conforming to ASSE 1017 to limit the domestic hot water temperature to a maximum of 140°F.
Ideal water temperature for baseboard heat. If you're running 140F water out with a 25F delta-T, the return water is ~115F and you're into the mid-90s for raw combustion efficiency, roughly 8-10% better than you're getting with 130F return water with only a 15F drop in temp. Below ~120F the output curve of fin tube is non-linear
