HT/HP High temperature above 350°F and High Pressure less than 300 PSIG. Closed System One in which the fluid is continuously circulated with no water make-up or lost fluid. Park-er Direct Fired Hot Water Boilers are well suited for this type of system. Open System One in which the fluid is heated and then used, so make-up is required. The Parker Indirect Heater is the unit of choice for this type of sys

Sep 18, 2020 · Efficiency of these condensing boilers is greatly increased by both lowered allowable water temperature, which improves log mean temperature difference of the heat transfer mechanism and by recovering the latent heat of vaporization from the fuels combustion. Efficiency of condensing boilers can be as high as 95% to 98%.
