Getting the Most Out of Your Commercial Condensing Boiler

Aug 13, 2015 · Most boilers are designed for a 20-25 degree temperature rise. If the system return water temperature is 150 degrees F, the supply water temperature to the system from the boiler should be 20-25 degrees F higher. A temperature span greater than the boiler design temperature rise could cause Thermal Shock inside the boiler.

Pressure/Temperature Relationship (Columns 1, 2 and 3). For every pressure of pure steam there is a corresponding temperature. Example: The temperature of 250 psig pure steam is always 406°F. Heat of Saturated Liquid (Column 4). This is the amount of heat required to raise the temperature of a pound of water from 32°F to the boiling point at

ANSI Standard Z21.13 tests and rates condensing boiler performance with an 80˚F (27˚C) boiler entering water temperature (EWT) and a 100˚F (55˚C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT) of 180˚F (82˚C). Condensing boiler performance is dominated by the boiler EWT. Figure 1 below shows a typical
