If your tank is set for 130* the water temps you pull into the desuperheater will be about 125*. That includes turning the heat down perhaps even off completely -- when they're not at home. Hence, this results in a loss of efficiency. Desuperheater is used for carrying out the desuperheating process which is to reduce the temperature of the superheat and to bring back the vapor into a saturated state. The hot water spray is maintained at a temperature close to the steam saturation temperature at the exit of the equipment. The steam that is used in this system is either fresh steam or steam that is bled. 5. Desuperheater is used for carrying out the desuperheating process which is to reduce the temperature of the superheat and to bring back the vapor into a saturated state. I had to turn my water heater up to get the same temp that I had during the summer.
