As we mentioned in our article about natural gas pressure for restaurant equipment, WC derives from the pressure required to move one inch of water up a U-tube. yoctopascal We use a manometer or a Magnehelic and measure the negative air pressure in the system return side before the blower (and after the filter whenever possible) and the positive pressure supply air side directly after the blower. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1F. You can put the information in writing and make clients sign the paperwork to ensure that they understand the expectations youve set. (8.33 pounds X 60 minutes = 500) The second piece of the formula and sometimes the hardest to identify is the flow rate in GPM, or the system gallons per minute. Tankless water heaters can be a great solution to provide hot water; however, most tankless water heaters have a BTU capacity ranging from 140,000 to 200,000 or more, which makes a tankless water heater one of the largest single appliances on a typical gas system.
